Adipokine/hepatokines profiling of fatty liver in adolescents and young adults: cross-sectional and prospective analyses of the BCAMS study.

The underlying connections between obesity and non-alcoholic fatty liver disease (NAFLD) are not fully understood. One potential link might be the imbalanced adipokines and hepatokines. We aimed to explore the associations between specific adipokines/hepatokines and NAFLD in Chinese youth and to determine how these biomarkers mediate the obesity-NAFLD relationship. We analyzed data from the 10-year follow-up visit of the Beijing Children and Adolescents Metabolic Syndrome (BCAMS) study (n = 509; mean age = 20.2years) for a comprehensive metabolic risk assessment, including liver ultrasound and plasma measurements of adiponectin, leptin, fibroblast growth factor 21 (FGF21), retinol-binding protein 4 (RBP4), and angiopoietin-like protein 8 (ANGPTL8). Longitudinal analysis was performed on a subgroup (n = 307), with complete baseline (mean age = 12.2years) and follow-up data. Mediation models assessed how obesity at baseline and follow-up influence NAFLD through these biomarkers. Participants with NAFLD exhibited a high prevalence of central obesity (90.9%). Both cross-sectional and prospective analyses identified increased RBP4, FGF21, leptin, and decreased adiponectin levels as significant predictors of NAFLD. More adipokine/hepatokine abnormalities were linked to higher NAFLD risk. Furthermore, ratios reflecting adipokine/hepatokine imbalances, including leptin/adiponectin, FGF21/adiponectin, and RBP4/adiponectin, demonstrated stepwise changes correlating with NAFLD severity (all p < 0.05). Mediation analysis indicated that these four adipokines/hepatokines accounted for approximately 72.4% of the central obesity-NAFLD relationship and 80.1% in the subgroup analysis using baseline childhood data. Dysregulated adipokines/hepatokines may explain the onset or progression of obesity-related NAFLD in youths. Higher RBP4, FGF21 and leptin, alongside lower adiponectin, could serve as early biomarkers for NAFLD.

Relationship Between Eating Patterns, Physical Activity, and Obesity Incidence Among Madrasah Tsanawiyah (MTs) Students

Obesity is a chronic disease characterized by excess body fat, increasing the risk of type 2 diabetes, heart disease, bone disorders, reproductive issues, and cancer, while also affecting quality of life, including sleep and mobility. According to WHO, the prevalence of overweight children and adolescents aged 5–19 years increased from 8% in 1990 to 20% in 2022. Recent data from the Ministry of Health in 2023 shows a high prevalence of central obesity among those aged 15–24 years, with 8.3-9.2% in males and 23.4-24.7% in females. This quantitative research employs an observational analytic design with a cross-sectional approach, using SPSS with the Chi-Square test to identify the relationship between dietary patterns and physical activity with the incidence of obesity among MTS students in Gowa Regency. Results indicate no significant relationship between dietary patterns (FFQ and IDDS) and obesity incidence, with p-values of 0.895 and 0.066, respectively. Similarly, physical activity showed no significant relationship with BMI, with a p-value of 0.056. Future studies should consider expanding variables to include factors influencing students' dietary patterns and physical activity, and conduct in-depth analyses using multiple regression.

Investigation of metabolic syndrome among people living with HIV: insight from a comparative study

PurposeThis study aims to investigate the prevalence of metabolic syndrome (MetS) among people living with HIV (PLWHIV) considering a comparative study.Design/methodology/approachA comparative cross-sectional study was carried out with 247 respondents which include 123 HIV patients and 124 people without HIV (PWoH) recruited using a simple random sampling method. Anthropometric measurements were taken using the standard procedures and instruments. Systolic and diastolic blood pressure was measured in all the subjects. The lipid level and blood glucose were obtained using a vacutainer method to collect at least 5 ml of venous blood into a heparin-containing bottle and fluoride bottle, and a chemical pathology analysis was conducted at the pathology laboratory.FindingsUsing the International Diabetes Federation criteria, the overall prevalence of MetS was 21.1%, while 27.6% and 14.5% prevalence were observed among the PLWHIV and PWoH, respectively. In all, 4% of the respondents were underweight, 40.9% had normal body mass index, 29.6 were overweight and 18.6 were obese I. The mean total cholesterol and triglycerides (TG) for PLWHIV and controls were 162.59 ± 37.80, 177.54 ± 34.23, 91.62 ± 51.74 and 69.59 ± 33.87 mg/dl, respectively. There was no significant association between gender and MetS. Of all the determinants of MetS, central obesity has the highest prevalence (71.5%, 65.3%) among the PLWHIV and the controls. Raised TGs were the components of MetS with the least prevalence (9.8% and 4.8%) among PLWHIV and PWoH. There was a significant association between reduced high-density lipoprotein cholesterol (HDL-C) (p = 0.001) and raised blood pressure (p = 0.001) of PLWHIV and PWoH. This study reveals that the burden of MetS among PLWHIV is higher than apparently healthy individuals.Research limitations/implicationsThis study could not measure the association between specific antiretroviral therapy (ART) regimens and MetS because all the PLWHIV in the study are on one regimen Tenofovir disoproxil/lamivudine/dolutegravir. Therefore, longitudinal studies on the extent of ART on MetS should be carried out while using newly diagnosed HIV patients who are not yet on ART as controls.Practical implicationsPrevalence of MetS and its components toward the high range among PLWHIV compared to the PWoH who are apparently healthy individuals was found. Higher prevalence of central obesity and reduced HDL-C among PLWHIV was also found. Overall, MetS is high among PLWHIV, and this might predispose them to adverse metabolic diseases such as cardiovascular diseases, diabetes and kidney diseases among others. Therefore, screening for metabolic risk factors should be adopted as part of routine HIV care.Originality/valueThe findings reveal the magnitude of MetS among PLWHIV compared to the apparently healthy individuals.

Determinants of central obesity in children and adolescents and associated complications in South Africa: a systematic review.

Central obesity in children is a global health concern associated with cardiovascular risk factors. In 2019 the World Obesity Federation predicted that in 2025, 206 million children and adolescents aged 5 to 19 will be obese, and the number is estimated to reach 254 million by 2030. There is limited literature on the factors that are associated with the development of central obesity in children. We report a systematic review, aimed to describe the current literature on determinants of central obesity and its associated health outcomes in children and adolescents in the South African population. We searched for peer-reviewed studies in Google Scholar, PubMed, and Science Direct search engines, and about seven studies were included. This systematic review has been registered with the International Prospective Register of Systematic Reviews (PROSPERO) (Registration number: CRD42023457012). This systematic review was conducted and reported according to an updated version of the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. The quality of the included studies was assessed by following guidelines from the Newcastle-Ottawa Scale (NOS). The method considered three main domains: selection, comparability, and outcome across different study designs. The prevalence of central obesity in children and adolescents by waist-to-height ratio (WHtR) ranged from 2.0 to 41.0%; waist-to-hip [WHR ranged from 10 to 25%; waist circumference (WC) ranged from 9 to 35%]. Central obesity was associated with age, physical inactivity, gender socio, and demographic profiles of the household. Central obesity in children was associated with cardiovascular diseases and mental health issues. Central obesity in children and adolescents was determined by gender, pubertal development, and age of the parents, households with high socioeconomic status, dietary practices, and overweight/obesity. Given the high prevalence of central obesity in children which can ultimately result in cardiometabolic diseases, cardiovascular risk factors, and mental health issues. This highlights the need for systems, jointly initiated by healthcare providers, policymakers, and the general society aimed at reducing the burden of central obesity such as introducing children and adolescents to health-promoting lifestyles.

Trends in prevalence of obesity and its association with hypertension across socioeconomic gradients in rural Yunnan Province, China

BackgroundThis study aimed to uncover the changing prevalence of obesity and its association with hypertension across socioeconomic gradients in rural southwest China.MethodsData were collected from two cross-sectional health interviews and surveys from 2011 to 2021 among individuals aged ≥ 35 years in rural China. Each participant’s height, weight, waist circumference, and blood pressure were measured. The overall prevalence of obesity, central obesity, and hypertension was directly standardized by age based on the total population of the two surveys. Multivariate logistic regression was used to analyze the association between obesity and prevalence of hypertension and an individual socioeconomic position (SEP) index was constructed using principal component analysis.ResultsFrom 2011 to 2021, the prevalence of obesity, central obesity, and hypertension increased substantially, from 5.9%, 50.2%, and 26.1–12.1%, 58.0%, and 40.4% (P < 0.01), respectively. These increasing rates existed in all subcategories, including sex, age, ethnicity, education, annual household income, access to medical services, and SEP (P < 0.05). In both 2011 and 2021, lower education level and poor access to medical services correlated with higher prevalence of central obesity, while higher SEP correlated with higher prevalence of obesity and central obesity (P < 0.01). Prevalence of obesity was higher in the Han ethnicity participants and individuals with poor access to medical services than in their counterparts (P < 0.01). Whereas the prevalence of central obesity was lower in Han participants than in ethnic minority participants in 2011 (P < 0.01), this trend reversed in 2021 (P < 0.01). A positive relationship between annual household income and prevalence of obesity and central obesity was only found in 2021 (P < 0.01). Obese and centrally obese participants were more likely to be hypertensive in both survey years (P < 0.01).ConclusionsFuture interventions to prevent and manage obesity in rural China should give increased attention to high income, less educated, poor access to medical services, and high SEP individuals. The implementation of these obesity interventions would also help reduce the prevalence of hypertension.

Central obesity, obesity, and physical activity among university staffs

Waist circumference (WC) is considered as a superior indicator to predict central obesity and its related comorbidities. Limited studies were conducted to infer central obesity using WC among university staffs. A cross-sectional study through the convenience sampling method was employed using the short form international physical activity questionnaire, anthropometric measurements, and WC measurement to infer a level of physical activity, body mass index (BMI), and central obesity. Seventy staff from three private universities in Malaysia participated in this study. There is a high prevalence (78.6%) of central obesity among the participants irrespective of their age. Majority of the participants fall under the overweight (37.1%) and obese (21.4%) category of BMI 48.6% reported to be involved in low level of physical activity. No difference in prevalence of central obesity based on age, gender, and level of physical activity. There is a moderately strong correlation between BMI and WC. In this study notably a high prevalence of central obesity in participants with underweight and desirable weight category of BMI was reported, which synergizes the concept of including WC measurement in health promotion activities. Appropriate multi- component and multi-level interventions can be considered to this population to prevent/combat obesity.

Chronic spontaneous urticaria and metabolic syndrome: a relationship conundrum.

Chronic spontaneous urticaria (CSU) and metabolic syndrome (MetS) are associated with low-grade inflammation. Despite intensive research and various hypothesis, there is lack of specific pathomechanisms of urticaria. Previous studies have suggested low-grade inflammation in obesity which may be linked to urticaria. However, there is limited literature on association of MetS and CSU. So, this study was conducted to evaluate the association of MetS and its components in patients with CSU. This was a hospital-based and cross-sectional cohort study in which 481 patients of CSU and 240 age- and gender-matched controls were recruited. MetS was defined using the revised National Cholesterol Education Program Adult Treatment Panel III. BMI, waist circumference, blood pressure, fasting blood sugar, plasma insulin, and lipid profile were measured after overnight fasting. Pearson's Chi-squared test was used to calculate significance. Logistic regression analysis was done to assess MetS as a predictor of CSU. All patients were started on antihistamines according to the severity of the disease. CSU patients comprised 220 men (45.7%) and 261 women (54.3%) with 97 patients (20.12%) qualifying criteria for metabolic syndrome compared with 73 (30.42%) controls without any significant difference (p = 0.177). CSU was significantly associated with a higher prevalence of central obesity (p = 0.003) but CSU patients with central obesity did not have a higher urticaria activity score (p = 0.727) or serum IgE levels (p = 0.359). In conclusion, our study found an increased association of central obesity with CSU that was not related to the severity of urticaria. This is of significance as obesity is the most prevalent and first component of MetS to be developed. There was no increase in the overall prevalence of MetS in patients with CSU. The increased association of obesity and urticaria in our study can be partially explained by the role of antihistamines in modulation of metabolic pathway and appetite. Future research into the same can give better insights and thus can aid in better management options in CSU patients.

Psoriasis and Its Association with Metabolic Syndrome: A Case–Control Study at a Tertiary Care Center in a Semi-Urban Region of South India

Background: Metabolic syndrome (MS) has been associated with skin diseases such as psoriasis. They share a common inflammatory pathway and therefore have an impact on each other. Objectives: To estimate the prevalence of MS and its individual components in psoriasis patients to that of the controls and to compare the characteristics in psoriasis patients with and without the MS. Materials and Methods: One hundred patients with a clinical diagnosis of chronic plaque psoriasis were evaluated for the prevalence of MS and compared with the age- and sex-matched controls. Results: The study population belongs to the semi-urban region with a low socioeconomic status. The psoriatic cases showed male preponderance, and the majority of the subjects belonged to 31–40 years of age group. The mean psoriasis area severity index score among cases was 26.19 ± 10.8, and 92% of cases were with severe disease affecting the quality of life. MS was found to be statistically significant in cases. The cases with MS had a higher prevalence of central obesity, hypertriglyceridemia, elevated fasting blood glucose levels, and hypertension. The presence of MS in psoriasis patients was statistically independent of the severity. Conclusions: Psoriasis patients should be periodically evaluated for metabolic syndrome to prevent the associated mortalities and for their effective management.

The diet assessment clarifies cardiovascular risk

Background and Aims : To determine the quality characteristics of nutrition in individuals with low cardiovascular risk (SCORE 2 < 2,5%) and to assess the relationship of nutritional characteristics with metabolic disorders and body composition.Methods: The study included 90 patients: 43.8 ± 3.2 years, 37 men (47%) and 41 womеn (53%). 62 (69%) participants with central obesity (CO), low cardiovascular risk (SCORE ≤1%, SCORE 2 < 2,5%, CMDS 0-1). All patients were provided with a nutritional questionnaire consisting of 11 questions.Results: Inappropriate nutrition was registered in all patients with CO. A number of diet factors had a correlation with TG, LDL, TC, WC, body fat mass, hepatic steatosis and epicardial fat. Among them: processed meat (r = 0.3; r = 0.4; r = 0.3; r = 0.4; r = 0.4; r = 0.4; r = 0.48, respectively; p = 0.001), the absence of nuts (r = 0.4; r = 0.4; r = 0.3; r = 0.4; r = 0.4; r = 0.4; r = 0.3, respectively; p = 0.001), insufficient quota of fruits and vegetables (r = 0.7; r = 0.7; r = 0.6; r = 0.7; r = 0.7; r = 0.5; r = 0.7 , respectively; p = 0.001). It is important that according to the nutritional scale the cardiovascular diseases risk became higher in 57% of patients.Conclusions: The low cardiovascular risk group is very heterogeneous due to the high prevalence of central obesity and unbalanced nutrition. The food scale helps to identify problem areas of the diet within 2 minutes.

Cardiometabolic profiles in women with adenomyosis

The aim of this study was to investigate the reproductive profiles, metabolic parameters and cardiometabolic risk assessed by surrogate indexes in women with adenomyosis. Ninety-six premenopausal women who were diagnosed with adenomyosis by transvaginal ultrasound and 97 age-body mass index (BMI) matched controls with normal ultrasound during routine examination were included. Women with adenomyosis were more likely to have higher gravidity and had more abortions than women without adenomyosis. Regarding the individual metabolic syndrome components, the adenomyosis group was more likely to have higher prevalence of hypertension, low HDL-C and central obesity. No significant difference was found between the groups in terms of visceral adiposity index, lipid accumulation product and fatty liver index. Only higher blood pressure (BP) remained statistically significant after adjustment for confounding factors in multivariate analysis. Women with adenomyosis had remarkably high risk of hypertension. It may be advisable to monitor their BP closely. Impact Statement What is already known on this subject? The only anthropometric characteristic assessed in women in relation to adenomyosis is body mass index (BMI). A case-control study showed that women who are obese are more likely to have adenomyosis. The gravidity, number of spontaneous abortions and previous uterine surgeries such as dilatation and curettage (D&C) and caesarean section were found significantly associated with adenomyosis. What do the results of this study add? A remarkable finding of our study was the increased incidence of higher systolic BP in women with adenomyosis. No difference was observed in adiposity indices between women with and without adenomyosis. Higher prevalence of central obesity and lower HDL-C levels were seen in women with adenomyosis. What are the implications of these findings for clinical practice and/or further research? The study identifies that adenomyosis is associated with an increased risk of hypertension, and women with adenomyosis may be monitored closely for blood pressure changes. Our report also provides novel information about the metabolic risk profiles associated with adenomyosis.

Cardiovascular risk factors among private primary school teachers in Onitsha North Local Government Area, Anambra State

Background: Prevalence of cardiovascular risk factors has continued to increase due to changes in dietary practices and increased physical inactivity among the adult population.&#x0D; Objective: This study was designed to assess the prevalence of cardiovascular risk factors among private primary school teachers in Onitsha North Local Government Area, Anambra State, Nigeria.&#x0D; Subjects and methods: A cross-sectional survey design was employed and a multistage sampling technique was used to select 400 respondents used in the study. Questionnaire was used to obtain information on the sociodemographic characteristics, dietary habits, physical activity level, and lifestyle characteristics of the respondents. Anthropometric indices (body mass index and waist-hip ratio), blood pressure, blood glucose, and lipid profile of the respondents were obtained using standard procedures. Data obtained were coded and entered into the computer and analyzed using SPSS for windows version 21. Chi-square was used to determine the relationship existing among variables. Significance was accepted at p &lt; 0.05.&#x0D; Results: Results showed that the majority (90%) of the respondents were females while a few (9.8) were males. Most (69.5%) of the respondents skipped meals while some (30.5%) did not skip meals. A high prevalence of central obesity (57.0% WC, 47.5% WHR), hypertension (20.0%), impaired plasma glucose (30.0%), diabetes mellitus (2.5%), low HDL-cholesterol (37.5%) and hypertriglycerideamia (15%) was observed among the respondents. Female respondents were significantly (p &lt; 0.05) more centrally obese (60.0% WC, 51.55% WHR) than males (40.0% WC, 28.6% WHR). No significant (p &gt; 0.05) relationship was found between gender and blood pressure, blood glucose level, and lipid profile of the respondents.&#x0D; Conclusion: The study concluded that the prevalence of cardiovascular risk factors was high among the respondents

Impact of Lipid Genetic Risk Score and Saturated Fatty Acid Intake on Central Obesity in an Asian Indian Population.

Abnormalities in lipid metabolism have been linked to the development of obesity. We used a nutrigenetic approach to establish a link between lipids and obesity in Asian Indians, who are known to have a high prevalence of central obesity and dyslipidaemia. A sample of 497 Asian Indian individuals (260 with type 2 diabetes and 237 with normal glucose tolerance) (mean age: 44 ± 10 years) were randomly chosen from the Chennai Urban Rural Epidemiological Study (CURES). Dietary intake was assessed using a previously validated questionnaire. A genetic risk score (GRS) was constructed based on cholesteryl ester transfer protein (CETP) and lipoprotein lipase (LPL) genetic variants. There was a significant interaction between GRS and saturated fatty acid (SFA) intake on waist circumference (WC) (Pinteraction = 0.006). Individuals with a low SFA intake (≤23.2 g/day), despite carrying ≥2 risk alleles, had a smaller WC compared to individuals carrying <2 risk alleles (Beta = −0.01 cm; p = 0.03). For those individuals carrying ≥2 risk alleles, a high SFA intake (>23.2 g/day) was significantly associated with a larger WC than a low SFA intake (≤23.2 g/day) (Beta = 0.02 cm, p = 0.02). There were no significant interactions between GRS and other dietary factors on any of the measured outcomes. We conclude that a diet low in SFA might help reduce the genetic risk of central obesity confirmed by CETP and LPL genetic variants. Conversely, a high SFA diet increases the genetic risk of central obesity in Asian Indians.

MAFLD Predicts the Risk of Cardiovascular Disease Better than NAFLD in Asymptomatic Subjects with Health Check-Ups.

Metabolic dysfunction-associated fatty liver disease (MAFLD) was proposed to compensate for the conventional concept of nonalcoholic fatty liver disease (NAFLD). We investigated the superiority of MAFLD versus NAFLD in predicting the risk of atherosclerotic cardiovascular disease (ASCVD). A total of 2,144 subjects without a history of ASCVD, who underwent a comprehensive medical health check-up, were selected for the study. The associations between fatty liver status and coronary risk surrogates, such as coronary artery calcium score (CACS), coronary artery disease, quantitative stenosis grade, and 10-year ASCVD risk, were analyzed. MAFLD and NAFLD were identified in 995 (46.4%) and 891 (41.6%) subjects, respectively. Subjects with MAFLD or NAFLD were more likely to be male and had a significantly higher prevalence of central obesity, obesity, hypertension, diabetes, and dyslipidemia (all, p < 0.05) than their counterparts. In terms of coronary risk surrogates, the MAFLD or NAFLD population had a significantly higher proportion of subjects with CACS > 100, coronary artery disease, higher grade of coronary artery stenosis, and higher 10-year ASCVD risk (all, p < 0.05) than their counterparts. Multivariable logistic regression models showed an independent association between MAFLD/NAFLD and coronary risk surrogates (all, p < 0.05). However, NAFLD only, defined as 'NAFLD, but not MAFLD,' was not associated with an increased coronary risk, compared to MAFLD. Although both MAFLD and NAFLD discriminated different ASCVD risks, MAFLD predicted the risk of ASCVD better than NAFLD in asymptomatic subjects who underwent medical health check-ups.

Central Obesity in Axial Spondyloarthritis: The Missing Link to Understanding Worse Outcomes in Women?

To determine (1) the prevalence of central obesity in axial spondyloarthritis (axSpA) and its effect on disease-related outcomes and (2) how this differs between sexes. Data were extracted from the Ankylosing Spondylitis Registry of Ireland. Patients with physical measurements for the calculation of anthropometric measures were included. BMI and waist-to-hip ratio (WHR) were used to compare classifications of obesity. Comparison analyses based on sex and central obesity were carried out. Multivariate analysis examined the effects of these factors on the following patient-reported outcomes: the Bath Ankylosing Spondylitis Disease Activity Index (BASDAI), the Bath Ankylosing Spondylitis Functional Index (BASFI), the Ankylosing Spondylitis Quality of Life (ASQoL) questionnaire, and the Health Assessment Questionnaire (HAQ). In total, 753 patients were included in the analysis. Of these patients, 29.6% (n = 223) were classified as obese based on their BMI, and 41.3% (n = 311) were classified as centrally obese according to the WHR. The prevalence of central obesity was significantly higher among women with axSpA compared to men (71.6% vs 29.9%, P < 0.01). Central obesity had a clear effect on patient outcomes, regardless of sex. Presence of central obesity was associated with significantly worse BASFI scores (P < 0.01), HAQ scores (P < 0.01), and ASQoL questionnaire scores (P = 0.01), with a nonsignificant trend toward worse BASDAI scores (P = 0.07). There was a high prevalence of central obesity as assessed by the WHR in axSpA, most notably among women with axSpA. This modifiable comorbidity was significantly associated with worse quality of life, greater impairment of functional ability, and a trend toward worse disease activity. Regular use of the WHR to screen for central obesity as part of an axSpA assessment would provide an opportunity for prompt identification and intervention for at-risk patients.

Cross-sectional Study Shows an Association between Paediatric Lichen Planus and Dyslipidemia.

Few studies have shown an association between adult lichen planus and dyslipidemia, but none has shown an association with the pediatric population. We planned to study the association between pediatric lichen planus and metabolic syndrome (MS). This is a single-centre, cross-sectional, case-control study from July 2018 to December 2019 at a tertiary care institute. Twenty children in the age group of 6-16 years, diagnosed as cases of childhood/adolescent lichen planus, and 40 age- and sex-matched controls were included in this study and evaluated for metabolic syndrome.Patients' anthropometry including weight, height, waist circumference, and body mass index (BMI) was recorded. Blood samples were sent for the measurement of fasting plasma glucose, high-density lipoprotein (HDL), low-density lipoprotein (LDL) cholesterol, and triglyceride levels. The mean HDL was found to be significantly lower in children with lichen planus compared to children without lichen planus (p = 0.012), although there was no statistically significant difference in the frequency of patients having deranged HDL levels between the groups (p = 0.326). Children with lichen planus had a higher prevalence of central obesity, but the difference was not statistically significant (p = 0.101). There was no significant difference between mean BMI, hypertension, triglyceride, LDL, and fasting blood sugar values between the groups. Using the logistic regression analysis model, it was found that the strongest independent variable that impacts the occurrence of lichen planus was an HDL value less than 40 mg/dl (p = 0.017; OR 1.02 to 1.29). This study shows an association between paediatric lichen planus and dyslipidemia.

Abdominal Obesity in Overweight Schoolchildren from Portoviejo (Ecuador). Conicity Index Cut-Points for Sustainable Health

(1) Background: Abdominal obesity describes the accumulation of visceral fat. Monitoring of abdominal obesity in children aids prognosis of atherogenic risk and prediction of the emergence of different comorbidities, many of which persist into and throughout adulthood. For this reason, it is of great diagnostic value to the sustainability of health in populations. The aim of this study was to evaluate abdominal obesity in overweight schoolchildren from Portoviejo (Ecuador) and propose conicity index cut-points for sustainable health. (2) Methods: The sample was formed by 356 schoolchildren whose BMI z-score deemed them to be overweight. Height, weight, waist circumference (wstC), various skinfolds, percent body fat, conicity index (CI) and overweight classification according to wstC were determined. (3) Results: The mean age was 6.83 ± 1.2 years, 17.4% were obese, 34.8% were overweight and 47.8% were at risk of being overweight according to their BMI z-score. The mean height was 1.29 ± 0.12 m, whilst the mean weight was 35.21 ± 11.57 kg. When classifying according to wstC, 37.9% were identified as obese, 28.1% had high-risk abdominal adiposity and 34% were normal. The average CI was 1.16 ± 0.06, whilst that of body fat was 19.34 ± 6.03, with 56.2% of individuals having body fat values lower than 20%. (4) Conclusions: The sample showed a high prevalence of central obesity. Significant agreement was not found between classifications of nutritional status according to BMI z-score and wstC.

Setting \u2013 based prevalence and correlates of central obesity: findings from a cross-sectional study among formal sector employees in Dodoma City, Central Tanzania

BackgroundObesity at the workplace has been associated with symptoms of lower self-esteem, increased individual and employer healthcare costs, increased absenteeism and presenteeism and reduced productivity. Therefore, this study was designed to study the prevalence and correlates of central obesity among formal sector employees in Dodoma City.MethodsStudy design was a cross-sectional survey conducted from March to June, 2019. Participants were employees from formal sector employment defined as those paid regular monthly wage and with either a secured permanent or temporary contract. Simple random sampling was used to select four out of fifteen large buildings hosting various establishments. Respondents were obtained conveniently and interviewed face to face. Central obesity was defined as a waist circumference greater than 102 cm for males and greater than 88 cm for females. Chi-square test was conducted to assess the differences among the groups. Simple and multiple logistic regression models were fitted to identify the correlates of central obesity.ResultsA total of 392 respondents (98% response rate) agreed and participated in the study. The overall prevalence of central obesity was found to be 41.8% (164/392). The prevalence of central obesity was significantly higher among females (67.4% p < 0.001), respondents aged ≥51 years (60%, p = < 0.001), administrators (55.1% p = < 0.05), respondents with salary of > 1,000,000 Tanzanian Shilling (TSh.) per month (54.4%, p = < 0.05), respondents who eat homemade meals at the workplace (64.2%, p = < 0.05) and respondents with hypertension (62.5%, p = < 0.05). Correlates of central obesity were found to be female sex (AOR = 9.53; 95% CI: 5.49, 16.78), increased age, eating homemade meals at the workplace (AOR = 2.32; 95% CI: 1.04, 4.19) and hypertension (AOR = 3.15; 95% CI: 1.41, 6.91).ConclusionsThe present study revealed high prevalence of central obesity among formal sector employees in Dodoma City. Scholars and stakeholders are urged to generate more evidences and design appropriate interventions to curb the situation.

Prevalence of Obesity and Predictive Value of Central Obesity among Medical Doctors to Diagnose Hypertension

Introduction: Central obesity has been shown to have worse health outcomes than general obesity and plays a greater role in the causation of cardiovascular diseases. Prevalence of central obesity is high in Nigeria and is associated with increased cardiovascular risk. Aim: To assess the prevalence of central obesity in medical doctors in Bayelsa state using four obesity indices and to determine the association between these indices and compare the ability of these indices to predict cardiovascular risk. Materials and Methods: This was a descriptive cross-sectional study conducted between August 2018 and January 2019. Using a structured self-administered questionnaire, data was collected from 244 randomly selected medical doctors. Data included socio-demographic information, work duration and professional cadre, Blood Pressure (BP) was taken. Anthropometric measures which included weight (in Kg), height (in metres), Waist Circumference (WC) and Hip Circumference (HC) in centimeters was taken. From the different measures: Waist-Hip Ratio (WHpR), Waist-Height Ratio (WHtR), Body Mass Index (BMI) was calculated. Based on WHO recommended thresholds, WC, WHpR, WHtR and BMI were used in categorising participants as obese and non-obese. Correlation analysis was done and Receiver Operating Characteristic (ROC) curve was constructed. Statistical significance was set at p-value &lt;0.05. Results: Most doctors in the study were less than 30-year-old (40.2%), married (54.9%) and female doctors made up a third of the respondents (29.9%). The mean age of study participants was 37.4 years (SD-11.3 years) and mean duration of medical practice was 9 years (SD-11.1 years). The prevalence of elevated BP was 26.6% using a BP threshold of ≥140/90 mmHg. The prevalence of obesity was 18.4% using BMI ≥30 kg/m2. Based on WC, WHtR, and WHpR categorisations, the prevalence of obesity was 44.3%, 58.2%, and 63.1%, respectively. The weakest relationship existed between BMI and BP (r=0.15; p=0.019); while the correlation coefficient (r) between WC and WHtR showed a very strong positive relationship (r=0.88; p=0.001). ROC curve analysis revealed all anthropometric indices obtained modest performances in predicting Cardiovascular Diseases (CVD) risk as indicated by AUC values that were equal to or higher than 0.60. WC performed best in predicting hypertension in study participants (0.69) while BMI was the worst performer (0.60). Conclusion: A high prevalence of central obesity in medical doctors is worrisome given the associated cardiovascular risks. This study shows all four anthropometric indices (WC, WHtR, WHpR and BMI) are useful in predicting cardiovascular risk, with the best and worst predictors being WC and BMI, respectively.

Isolated systolic hypertension and central blood pressure: Implications from the national nutrition and health survey in Taiwan.

We aimed to investigate the association between isolated systolic hypertension (ISH) and central blood pressure (BP) in a nationally representative population, with a focus on the young and middle‐aged adults (<50 years old). A total of 2029 adults without taking antihypertensive medications, aged ≥ 19 years old, participated in the 2013–2016 National Nutrition and Health Survey in Taiwan. Central and brachial BP were simultaneously measured using a cuff‐based stand‐alone central blood pressure monitor purporting to measure invasive central BP (type II device). Central hypertension was defined by central systolic (SBP)/diastolic BP (DBP) ≥130 or 90 mm Hg, and ISH was defined by brachial SBP ≥ 140 and DBP < 90 mm Hg. Overall, the prevalence rates of ISH, isolated diastolic hypertension (IDH, brachial SBP < 140 and DBP ≥ 90 mmHg), and systolic/diastolic hypertension (SDH, brachial SBP ≥ 140 and DBP ≥ 90 mmHg) were 6.51%, 1.92%, and 4.34%, respectively. ISH subjects had significantly higher central pulse pressure (PP) (62.8 ± 9.7 mm Hg for age < 50 years and 72.4 ± 13.5 mmHg for age ≥ 50 years) than those subjects with either IDH (44.7 ± 10.7 and 44.9 ± 10.6 mmHg) or SDH (55.2 ± 14.0 and 62.6 ± 17.1 mmHg). All ISH adults had central hypertension, and a higher prevalence of central obesity than the normotensives (80.95% vs. 26.15%, for age < 50 years; and 63.96% vs. 43.37% for age ≥ 50 years). All untreated subjects with ISH, whether younger or older, had central hypertension and had significantly higher central PP than those with IDH or SDH. Central obesity was one of the major characteristics of ISH, especially in the young‐ and middle‐aged adults.

Screening of central obesity among normal-weight children and adolescents in Shandong, China.

The prevalence of central obesity in the total population has been reported in numerous studies. However, information on the prevalence of central obesity within normal-category BMI is scant. In the present study, we examined the profiles of central obesity among normal-weight children and adolescents. A total of 29516 (14226 boys and 15290 girls) normal-weight children and adolescents (excluding underweight, overweight and obesity) aged 7-18 years were included in the final analysis. Central obesity was defined by the international age- and sex-specific cut-offs of waist circumference (WC) and threshold of waist:height ratio (WHtR ≥ 0·5). All subjects were classified into four groups (Q1-Q4) according to the age- and sex-specific quartiles of BMI, those in the upper fourth (Q4) were defined as 'high-normal BMI' and those in the lower fourth (Q1) were defined as 'low-normal BMI'. The prevalence of central obesity as measured by WC was 9·90 (95 % CI 9·41, 10·39) % for boys and 8·11 (95 % CI 7·68, 8·54) % for girls; by WHtR was 2·97 (95 % CI 2·69, 3·25) % for boys and 2·44 (95 % CI 2·20, 2·68) % for girls. Subjects in the Q4 group had a much higher prevalence of central obesity than their counterparts in the Q1 group (P < 0·01). Our findings suggest that the health risks of children with normal-weight central obesity may be missed when BMI is used alone as a measure; it is meaningful to include WC in clinical practice and to include the simple message 'Keep your waist to less than half your height'.
