Assessment of Nutritional Status Among Undergraduate Students at a Nairobi Tertiary Institution Using BMI and Waist Circumference Metrics

This study investigated the impact of dietary and lifestyle changes on the nutritional status of undergraduate students during their transition to university life and the associated risk for non- ommunicable diseases. A review of global studies indicated varying prevalence rates of overweight and obesity among university students, influenced by diet, physical activity, and sleep patterns. This research specifically assessed the nutritional status of Kenyatta University students in Nairobi, Kenya, with an emphasis on the limited studies utilizing both BMI and waist circumference for assessment. Employing a cross-sectional, analytical design, the study was conducted at Kenyatta University Main Campus in Nairobi County. This public research university, founded in 1970, was selected for its urban setting and its representation of young adults. The target population comprised undergraduate students pursuing bachelor’s degrees, with inclusion criteria of voluntary participation and at least six months on campus. Multi-stage stratified sampling was used to select 260 participants. Data were collected through a structured questionnaire, pretested on 10% of the sample, with reliability assessed via a test-retest method. Anthropometric measurements were taken by trained research assistants. Data analysis was performed using SPSS version 24, evaluating nutritional status with BMI and waist circumference. Ethical considerations and COVID-19 protocols were rigorously observed. Findings revealed that, based on BMI, 67.5% of respondents had normal weight, while 8.4%, 16.5%, and 7.6% were underweight, overweight, and obese, respectively. The overall prevalence of overweight and obesity (BMI ≥ 25) was 24.1%. Female respondents showed a higher prevalence of obesity (63.2%) and overweight (73.2%) compared to males. In the underweight category, more males were underweight (57.1%) than females. Waist circumference assessment indicated that 21.7% had abdominal obesity, with a higher prevalence among females (87%) compared to males (13%), highlighting a gender-based risk factor for abdominal obesity. The study’s BMI analysis revealed a substantial proportion of respondents within the normal weight range, with significant gender disparities in obesity and overweight prevalence. The waist circumference assessment underscored a notable occurrence of abdominal obesity, particularly among females, indicating gender-specific susceptibility to this health concern.

Spicy food consumption is associated with abdominal obesity among Chinese Han population aged 30–79 years in the Sichuan Basin: a population-based cross-sectional study

BackgroundFew animal experiments and volunteer-based intervention studies have showed a controversial effect of spicy foods on abdominal obesity. We aimed to examine the association between spicy food frequency, spicy flavor, and abdominal obesity among Chinese Han population in the Sichuan Basin which area eating spicy foods relatively often.MethodsA cross-sectional analysis was conducted using the Sichuan Basin baseline data from the China Multi-Ethnic Cohort (CMEC) study, including data from electronic questionnaires, anthropometric measurements and blood sample collection. A total of 40,877 adults (22,503 females) aged 30–79 years were included in the final analysis. Multivariable logistic regression yielded adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for abdominal obesity associated with the strength of spicy flavor and frequency of spicy food intake.ResultsThe prevalence of daily spicy food eating was 47.3% in males and 52.7% in females, the percentages of abdominal obesity were 52.3%, 48.8%, 51.6% and 55.5% in the spicy food intake subgroups of never, 1–2 days/week, 3–5 days/week and 6–7 days/week, respectively. Compared with males who never consumed spicy food, the adjusted ORs (95% CIs) in the 1–2 days/week, 3–5 days/week and 6–7 days/week subgroups were 1.21 (1.09, 1.34), 1.35 (1.21, 1.51), and 1.35 (1.25, 1.47), respectively (Ptrend < 0.001). The corresponding odds ratios for females were 0.95 (0.87, 1.05), 1.14 (1.03, 1.26), and 1.25 (1.16, 1.35), respectively (Ptrend < 0.001). Similarly, compared with no spicy flavor, the adjusted ORs (95% CIs) of mild, middle, and strong spicy strength for abdominal obesity in males were 1.27 (1.17, 1.38), 1.51 (1.37, 1.67), and 1.36 (1.11, 1.67) respectively (Ptrend < 0.001). The corresponding odds ratios for females were 1.14 (1.06, 1.23), 1.27 (1.15, 1.40), and 1.32 (1.06, 1.65), respectively (Ptrend < 0.001).ConclusionsThe data indicated that spicy food consumption was a risk factor for abdominal obesity among Chinese adult population in the Sichuan Basin. The results need to be approved by large cohort studies.

Early rapid weight gain, parental body mass index and the association with an increased waist-to-height ratio at 5 years of age.

Background/ObjectivesObesity-related adverse health consequences are closely associated with abdominal obesity. Risk factors for overweight and obesity have been studied but there is a lack of information regarding risk factors for abdominal obesity, especially in the preschool population. The aim of the present study was to examine early life risk factors for an increased waist-to-height ratio (WHtR) in children at five years of age and, in addition, to investigate if these risk factors also were associated with overweight or obesity.Subjects/MethodsThe study population comprised 1,540 children from a population-based longitudinal birth cohort study that included 2,666 Swedish children. The children were included if they had complete growth data for the analyses used in this study. Children were classified as having WHtR standard deviation scores (SDS) ≥ 1 or < 1 at five years of age, according to Swedish reference values, and as having body mass index standard deviation scores (BMISDS) for overweight/obesity, or normal weight/underweight according to the International Obesity Task Force criteria. Associations between child-related, socioeconomic status-related, parental health-related and nutrition- and feeding practice-related factors during the first two years and a WHtRSDS ≥ 1 or a BMISDS for overweight/obesity at five years were investigated with logistic regression analyses.ResultsAt five years of age, 15% of the children had WHtRSDS ≥ 1 and 11% had overweight or obesity. In multivariable analyses, rapid weight gain (RWG) during 0–6 months (OR: 1.90, 95% CI: 1.23–2.95, p = 0.004), maternal pre-pregnancy BMI (1.06, 1.01–1.11, p = 0.019) and paternal BMI (1.11, 1.01–1.21, p = 0.028) were associated with WHtRSDS ≥ 1. RWG during 0–6 months (2.53, 1.53–4.20, p<0.001), 6–12 months (2.82, 1.37–5.79, p = 0.005), and maternal pre-pregnancy BMI (1.11, 1.06–1.17, p<0.001) were associated with overweight or obesity.ConclusionsEarly risk factors, including rapid weight gain, are associated with increased WHtRSDS and overweight or obesity at 5 years of age. Preventive interventions should target early RWG and parental overweight and obesity.

Prevalence and factors associated with abdominal obesity among Bangladeshi adults: Evidence from a nationally representative survey

This study aimed to estimate the prevalence and determine the associated factors of abdominal obesity among Bangladeshi adults (18–69 years) using the ‘Bangladesh STEPwise approach to surveillance (STEPS) survey 2018’ data. Abdominal obesity was defined as a waist-hip ratio of >0.90 for males and >0.85 for females. Multivariable log-binomial regression and logistic regression were conducted to investigate associated factors and were reported with an adjusted prevalence ratio (APR), adjusted odds ratio (AOR), and a 95% confidence interval (CI). The overall prevalence of abdominal obesity was 42.5%. Individuals aged 30–49 years and 50–69 years, with high educational attainment, being ever married, being overweight/obese, and residing in Barisal, Khulna, Rangpur, and Sylhet division were associated with both higher prevalence and higher odds of abdominal obesity. Females had 50% lower odds of being abdominally obese than male participants. Both urban residents and those with low physical activity had 20% higher odds of having abdominal obesity compared to rural residents and those with adequate physical activity, respectively. High risk groups should be targeted for the prevention and control of abdominal obesity. Multisectoral interventions should be launched by targeting the at-risk population for the underweight and overweight/obesity prevention programs irrespective of work status or place of residence. • The overall prevalence of abdominal obesity was 42.5%. • Females had 50% lower odds of being abdominally obese than male participants. • Older age, with high educational attainment, being ever married were some of the risk factors of abdominal obesity.

Association between abdominal obesity, screen time and sleep in adolescents

ObjectiveTo assess the association between abdominal obesity, food intake, sleep deprivation, and screen time in adolescents. MethodsThis cross-sectional study was conducted with 432 adolescents aged 14–19 years, from public and private schools. Anthropometric and body composition measures included body weight, waist circumference, body mass index for age, waist-to-hip ratio, waist-to-height ratio, and body fat percentage. Abdominal obesity was defined by age and sex specific cut-off points for waist circumference. Food intake, screen time, sexual maturation, and sleep duration were evaluated by self-administered questionnaires. ResultsThe prevalence of excess body weight and abdominal obesity was 16.7% and 27.5%, respectively. Students in the adult phase (post-puberty), with inadequate waist-to-height ratio, high body fat percentage, and screen time ≥ 3 h/day were, respectively, 2.5 (95% CI 1.40–4.46), 7.44 (95% CI 1.08–51.46), 2.79 (95% CI 1.04–7.50), and 1.43 (95% CI 1.24–3.89) more likely to have abdominal obesity. Low intake of unprocessed or minimally processed foods was associated with inadequate sleep duration, while high intake of ultra-processed foods was associated with high screen time. ConclusionsAbdominal obesity was associated with the adult phase, short sleep duration and high screen time. The degree of food processing was associated with screen time and sleep duration. Assessing the risk factors of abdominal obesity may be a useful strategy for preventing cardiovascular disease in adolescents.

The effects of weight fluctuation on the components of metabolic syndrome: a 16-year prospective cohort study in South Korea

BackgroundWeight fluctuation (WF) is highly prevalent in parallel with the high prevalence of intentional or unintentional dieting. The health risks of frequent WF for metabolic syndrome (MS) have become a public health concern, especially for health care providers who supervise dieting as an intervention to prevent obesity-related morbidity or to improve health, as well as for the general population for whom dieting is of interest. The aim of this study was to investigate the long-term effect of WF on the risk of MS in Koreans.MethodsThis study analyzed secondary data from the Korean Genome and Epidemiology Study, a 16-year prospective cohort study, on 8150 individuals using time-dependent Cox regression.ResultsWF did not increase the risk of MS in either normal-weight or obese subjects. In an analysis of the components of MS, greater WF significantly increased the risk of abdominal obesity (HR = 1.05, 95% CI = 1.02–1.07, p < 0.001) in normal-weight individuals. However, WF did not increase the risk of hyperglycemia, low high-density lipoprotein cholesterol levels, elevated blood pressure, or raised fasting glucose in normal-weight individuals, and it did not influence any of the components of MS in obese individuals.ConclusionSince WF was found to be a risk factor for abdominal obesity, which is the most reliable predictor of MS, it should be considered when addressing weight control. Further studies on cut-off points for the degree of weight loss in a certain period need to be conducted to help clinicians provide guidance on appropriate weight control.

Dietary diversity and physical activity as risk factors of abdominal obesity among adults in Dilla town, Ethiopia

Globally, the prevalence of obesity is on the rise and has nearly tripled since 1975. In Ethiopia, despite not having well-documented evidence, abdominal obesity has been increasing dramatically, particularly in urban settings. Therefore, this study is intended to determine the prevalence and risk factors of abdominal obesity among adults in Dilla town, Ethiopia. A community-based cross-sectional study was conducted between January and February 2018 in Dilla Town. A multi-stage sampling technique was employed to recruit 663 adults. The study was conducted in accordance with the World Health Organization (WHO) STEP wise approach. Waist circumference was measured using a flexible metric tape mid-way between the lowest rib and iliac crest with the participant standing at the end of gentle expiration. Abdominal obesity was determined using the International Diabetes Federation cutoff. A logistic regression model was fitted to identify risk factors of abdominal obesity. Adjusted odds ratio (AOR) with corresponding 95% confidence interval (CI) was calculated to show the strength of association. A total of 634 adults participated in the study with a response rate of 95.6%. This study revealed that 155 (24.4%) [95% CI: (21.50, 27.80)] adults were abdominally obese. Higher odds of being abdominally obese were noted among adults with a high [AOR = 4.61, 95% CI: (2.51-8.45)] and middle [AOR = 3.22, 95% CI: (1.76-5.88)] wealth rank, consuming less diversified diet [AOR = 2.05, 95% CI: (1.31-3.19)], physical inactivity [AOR = 2.68, 95% CI: (1.70-4.22)] and being female [AOR = 1.92, 95% CI: (1.13-3.28)]. The prevalence of abdominal obesity among adults in Dilla town is considerably high, and became an emerging nutrition related problem. Being in the middle and high wealth rank, physical inactivity, consuming less diversified diet, and being female were the risk factors of abdominal obesity.

Gender differences in the relationship between dietary energy and macronutrients intake and body weight outcomes in Chinese adults

BackgroundTo explore the gender differences in the relationship between dietary energy and macronutrients intake and body weight outcomes in Chinese adults.MethodsData from the China Health and Nutrition Survey (CHNS, 2015) for10,898 participants aged 18–64 years. Three consecutive 24-h dietary recalls was used to assess the dietary intake. Quantile regression models for body mass index (BMI) and waist circumference (WC) were performed separately for each sex.ResultsAdult males showed greater absolute intakes of energy and macronutrients as compared to females as per the body weight outcomes. A 10% increase in BMI resulted in an additional intake of 0.002–0.004 kcal/d of dietary energy, 0.032–0.057 g/d of fats, 0.039–0.084 g/d of proteins, and 0.018–0.028 g/d of carbohydrates across all quantiles in males (p < 0.05). A 10% increase in WC lead to an additional intake of 0.004–0.008 kcal/d of dietary energy, 0.051–0.052 g/d of carbohydrates across the entire quantile in males (p < 0.05), and an increased intake of 0.060–0.150 kcal/d of fat in females (p < 0.05).ConclusionsDietary fat intake could be the risk factor of abdominal obesity in women. The importance of gender-specific evidence should be considered before promoting macronutrient allocation for the prevention and treatment of obesity.

Does vitamin D status predict weight gain or increase in waist circumference? Results from the longitudinal Health 2000/2011 Survey.

To investigate whether vitamin D status predicts weight gain or increase in waist circumference during the 11-year follow-up in general adult population. A population-based longitudinal study. The study was conducted using data from the nationally representative Health 2000/2011 Survey. The analyses were based on regression models adjusted for sociodemographic and lifestyle factors. Weight, waist circumference and vitamin D status (serum 25-hydroxyvitamin D concentration analysed with radioimmunoassay) were measured from 2924 participants aged 30-64 years at baseline. In men, low vitamin D status at baseline predicted ≥10 % increase in waist circumference during the follow-up when adjusted for age only (OR for sufficient v. deficient S-25(OH)D 0·41; 95 % CI 0·25, 0·67; P for trend <0·01), but the association with weight gain was only borderline significant. After adjustment for potential confounders, low vitamin D status remained a significant predictor of increase in waist circumference, but the association with weight gain was further attenuated. In women, vitamin D status at baseline did not predict weight gain or increase in waist circumference. Our results suggest that vitamin D insufficiency may be a risk factor of abdominal obesity among men but not among women. In men, it may also increase the risk of weight gain. Further studies are required to confirm these findings and examine potential mechanisms behind them. There is also a possibility that vitamin D is a biomarker of healthy lifestyle rather than an independent risk factor for obesity.

Night shift work, short sleep and obesity

BackgroundObesity is associated with increased general mortality and comorbidities, it is multifactorial and some evidence has shown that sleep duration and shift work may be implicated in its pathogenesis.ObjectivesThe aim of this study was to evaluate the association between shift work, quality of life and obesity among healthcare workers of a Brazilian University Hospital.MethodsA cross-sectional study was performed from April 2013 to December 2014 with 200 workers of a University Hospital. Sociodemographic data were evaluated and BREF WHOQOL was used for quality of life. The physical activity was evaluated using the International Physical Activity Questionnaire (IPAQ), Chronotypes and daily sleep preference were investigated using Munich Chronotype Questionnaire (MCTQ). Venous blood was collected after 12-h of fasting for laboratory tests.ResultsIn this sample, the night shift workers had higher income and were older compared to day shift workers. Night shift workers sleep less hours, had higher weight, body mass index and abdominal circumference when compared to the day shift workers. Night shift workers had almost 3 times higher association with abdominal obesity independent of age and gender, than day shift workers. MCTQ parameters showed that night shift workers had lower sleep duration during working days and also during free days, associated with a higher level of social jetlag. Social jetlag had an association with obesity. We found no difference for quality of life between shifts.ConclusionsNight work was a risk factor for abdominal obesity, social jetlag was higher in night shift workers and it was associated with presence of obesity.

Longitudinal multilevel analysis of correlative factors of abdominal obesity among Chinese reproductive women

To longitudinally analyze the associations between physical activity, sedentary time and dietary intake levels with waist circumference and abdominal obesity among Chinese reproductive women. In the five rounds of "China health and nutrition survey" in 2004, 2006, 2009, 2011 and 2015, 2951 women aged 15-49 years old who participated in at least two rounds of surveys were selected as research objects. Physical activity and sedentary time data were collected by questionnaire survey, and food consumption data were collected by 24-hour retrospective method for 3 consecutive days. Analysis of variance was used to analyze the time difference of continuous variables. Chi-square test was used to analyze the differences in time distribution of classified variables. Linear multilevel model was used to analyze the relationships between waist circumference and different levels of physical activity, sedentary time and dietary intake. Logistic multilevel model was used to analyze the risk of abdominal obesity with different levels of physical activity, sedentary time and dietary intake. By incorporating physical activity, sedentary time and dietary intake levels into the multilevel model respectively, compared with the low level of leisure-time physical activity, the waist circumference of the medium level group increased by 0. 47 cm(P=0. 025); compared with low level of TV time, waist circumference of the medium and high level increased by 0. 49 cm(P=0. 033) and 0. 58 cm(P=0. 013), respectively, and the relative risk of abdominal obesity was 1. 13(P=0. 049) and 1. 17(P=0. 010), respectively; compared with the group with insufficient intake of dark vegetables, the waist circumference of the group with adequate intake decreased by 0. 82 cm(P&lt;0. 001), and the relative risk of abdominal obesity was 0. 87(P=0. 028); compared with the group with low level of pastry intake, the waist circumference of the high level group increased by 1. 16 cm(P&lt;0. 001) and the relative risk of abdominal obesity was 1. 33(P&lt;0. 001). By incorporating physical activity, sedentary time and dietary intake levels into the multilevel model simultaneously, there were still statistically significant differences between TV time and dietary intake levels with waist circumference and abdominal obesity and the statistical value did not change much. Compared with low level of TV time, the waist circumference of the medium and high level groups increased by 0. 54 cm(P=0. 028) and 0. 58 cm(P=0. 025), respectively, and the relative risk of abdominal obesity was 1. 15(P=0. 034) and 1. 18(P=0. 011), respectively. Compared with the group with insufficient intake of dark vegetables, the waist circumference of the group with adequate intake decreased by 0. 80 cm(P&lt;0. 001), and the relative risk of abdominal obesity was 0. 87(P=0. 027). Compared with the group with low level of pastry intake, the waist circumference of the high level increased by 1. 13 cm(P&lt;0. 001) and the relative risk of abdominal obesity was 1. 32(P&lt;0. 001). There was no statistical significance in physical activity level with waist circumference and abdominal obesity. Television time and dietary factors(insufficient intake of dark color vegetables and high consumption of pastry) are independent risk factors for abdominal obesity among Chinese reproductive women. Besides strengthening physical activity, the prevention of abdominal obesity in reproductive women should also strengthen the intervention measures to reduce TV time and promote appropriate dietary behaviors(increasing dark color vegetable intake and reducing pastry intake).

Midnight salivary cortisol secretion and the use of antidepressants were associated with abdominal obesity in women with type 1 diabetes: a cross sectional study

BackgroundAbdominal obesity is a risk factor for cardiovascular disease. The aim was to explore the influence of midnight salivary cortisol (MSC), antidepressants and sex on abdominal obesity in type 1 diabetes (T1D). We controlled for physical inactivity, smoking, depression and alexithymia.MethodsCross sectional study of 190 T1D patients (86 women/104 men, 18–59 years, diabetes duration 1–55 years), consecutively recruited from one specialist diabetes outpatient clinic. Anthropometrics, blood pressure, saliva and blood samples were collected, supplemented with data from electronic medical records. Depression and alexithymia were assessed by self-report instruments. MSC (nmol/l) was categorised into 3 levels: high MSC: (≥ 6.7) (n = 64); intermediate MSC: ≥ 3.7− < 6.7) (n = 64); low MSC (< 3.7) (n = 62). Abdominal obesity was defined as waist circumference (meters) ≥ 0.88 for women and as ≥ 1.02 for men. Multiple logistic regression analyses (Backward: Wald) were performed. The Hosmer and Lemeshow test for goodness-of-fit and Nagelkerke R2 were used to evaluate each multiple logistic regression analysis model.ResultsThe prevalence of abdominal obesity was three times higher in the women than in the men (24% versus 8%) (p = 0.002). Antidepressants were used by 10% of the women and by 4% of the men (p = 0.09). The prevalence of high MSC was 1.7 times higher in the women (43% versus 26%); the prevalence of both intermediate MSC (28% versus 38%) and low MSC (29% versus 36%) were lower in the women (p = 0.048). Significant associations with abdominal obesity were for all 190 patients: female sex (adjusted odds ratio (AOR) 3.4 (confidence interval (CI) 1.4–8.2)) and the use of antidepressants (AOR 4.3 (CI 1.2–14.8)); for the 86 women: high MSC (AOR 18.4 (CI 1.9–181)) and use of antidepressants (AOR 12.2 (CI 2.0–73.6)); and for the 104 men: alexithymia (AOR 5.2 (CI 1.1–24.9)).ConclusionsClear sex differences were demonstrated with a distinct higher prevalence of abdominal obesity, as well as a distinct higher prevalence of high midnight salivary cortisol in the women with type 1 diabetes. High midnight salivary cortisol secretion and the use of antidepressants were independent risk factors for abdominal obesity in the women.

The Study of the Impact of Genetic Polymorphism of Leptin Gene G2548A on Obesity and Its Related Traits

BackgroundLeptin is a neuroendocrine protein hormone with 167 amino acids mainly produced by adipose tissue that regulates food intake and energy expenditure to maintain relative stability of body weight and energy storage over long period of time. A single nucleotide polymorphism in leptin, consisting of G to A substitution at nucleotide −2548 upstream from ATG start site (LEP G‐2548A, rs7799039) has been found to influence leptin expression, possibly at the transcriptional level and was associated with increased leptin secretion in adipocytes. However, these high levels of leptin do not serve their function in controlling the obesity of these individuals possibly due to a condition known as ‘leptin resistance’.AimAssess the risk of the genetic polymorphism of leptin gene G‐2548A on obesity.Material and MethodA case‐control study which consisted of 66 individuals of different BMI (46 normal, 16 overweight and 4 obese). The different genotypes of leptin G‐2548A were determined by restriction fragment length polymorphism polymerase reaction after DNA extraction from saliva samples.ResultsA high risk of obesity was seen among carrier of AA genotype compared to other genotypes (GG&amp;GA) (OR=2.6, 95% CI= 0.9–7.5). Furthermore AA genotype was found to be a risk factor for abdominal obesity (OR=1.3, 95%CI= 0.5–3.7).ConclusionCarrier of AA genotype of leptin G‐2548A polymorphism are at risk of obesity.Support or Funding InformationRak Medical and Health Sciences UniversityThis abstract is from the Experimental Biology 2019 Meeting.

Obesidade abdominal e fatores associados em adultos atendidos em uma clínica escola

Objective: To determine the prevalence of abdominal obesity and identify the association between socioeconomic factors and lifestyle among adults attending a university health center. Methods: Retrospective and cross-sectional study conducted between March and April 2015 with 1,022 medical records of adults of both genders attending a university health center in the last five years. We collected sociodemographic data (gender, age, marital status, household income and education), anthropometric data (current weight, height, BMI and WC) and information on lifestyle (smoking, drinking and physical activity). The dependent variable was abdominal obesity, defined by the waist-height ratio (WHtR). Multivariate analysis was performed using the logistic regression method. Results: The prevalence of abdominal obesity was 79.8% according to WHtR and, according to BMI, excessive weight accounted for 77.1%. It was found that the ages 30-59 years were a risk factor for abdominal obesity for both genders, and for women when stratified. However, with regard to men, only the age group 50-59 years constituted a risk factor (OR=5.76; CI=1.13-29.35; p=0.035). Living with a partner (OR=1.53; CI=1.07-2.18; p=0.017) and drinking (OR=1.62; CI=1.09-2.40; p=0.015) constituted risk factors for both genders and also for men (OR=2.46; CI=1.02- 5.95; p=0.045). Conclusion: There was a high prevalence of abdominal obesity and it was associated with the age groups 30-59 years for women and 50-59 years for men, and living with a partner and drinking for both genders.

Association of Cardiorespiratory Fitness and Abdominal Obesity in Full Time Students from Countryside

PURPOSE: To evaluate the association of cardiorespiratory fitness (CF) and abdominal obesity in girls and boys. METHODS: 62 boys (mean age 13.4 ± 1.9 yrs.) and 78 girls (mean age 13.1 ± 0.9 yrs) from 5 public schools in Curitiba, Brazil. Weight (kg), height (m), maturational stage and waist circumference (WC) were evaluated. CF was evaluated through determination of the maximum volume of oxygen during the Come and Go 20 meters Test by Léger and categorized as very weak/weak, regular and good/excellent. Values are expressed as average and standard deviation, relative and absolute frequency. The Pearson Chi-Square and Fisher’s Tests were used to estimate the differences between categorical variables. Logistic Regression was used to evaluate risk factors for abdominal obesity. The level of significance was 5 % and sample gives 95% test power. RESULTS: 79.5% of the girls and 55% of the boys had satisfactory CF. 59.7% of the students with adequate WC had satisfactory CF (p=0.01). When evaluated by sex, corresponding numbers were 67.1% of the girls (p=0,41) and 50,9% of the boys (p=0,008). Logistic regression model selected CF as the main factor associated with abdominal obesity [OR: 0.29 (IC 95%:0.09 to 0.88) p=0,02], followed by maturational stage [OR : 5.03(IC 95%:1.0175 to 24.9168) p=0,04] and sex [OR : 0.99(IC 95%: 0.33 to 2.98) p=0,99]. CONCLUSION: CF was the strongest factor associated with abdominal obesity in full time students in countryside.

Association between serum osteocalcin level and visceral obesity in Chinese postmenopausal women.

A low serum osteocalcin level, visceral obesity and postmenopausal status are recognized risk factors for cardiovascular disease. We investigated the relationship between the serum osteocalcin level and visceral fat content in a population of Chinese postmenopausal women. In total, 1481 postmenopausal women (mean age ± standard deviation, 57·1 ± 4·8 years) were selected from the Shanghai Obesity Study. Abdominal fat accumulation was quantified using magnetic resonance imaging. Subjects with a visceral fat area (VFA) of ≥80 cm(2) were classified as abdominally obese. The total serum osteocalcin level was measured by electrochemiluminescence immunoassay. The median serum osteocalcin level was 20·66 μg/l (interquartile range, 16·88-25·42 μg/l). The overall prevalence of abdominal obesity was 49·1% (n = 727). Abdominally obese subjects had lower serum osteocalcin levels than did nonabdominally obese subjects [19·14 (16·02-23·82) vs 21·97 (18·14-26·77) μg/l, respectively; P < 0·001]. Partial correlation analysis showed that the serum osteocalcin level was still negatively correlated with VFA after adjusting for age, years since menopause and body mass index (P < 0·01). Moreover, VFA was independently associated with the serum osteocalcin level after adjustment for confounding factors (P < 0·05). A low serum osteocalcin level was an independent risk factor for abdominal obesity (odds ratio, 0·972; 95% confidence interval, 0·953-0·991; P = 0·004). The serum osteocalcin level was inversely correlated with the visceral fat content in these Chinese postmenopausal women.

Prevalence and risk factors of abdominal obesity in Polish rural children

Secular trends of body mass index (BMI) and waist circumference indicate greater increase in abdominal obesity compared to general obesity. Determinants of obesity described by BMI are relatively well documented in various populations, unlike abdominal obesity described by waist-to-height ratio (WHtR). The aim of the study was to determine prevalence and abdominal obesity (WHtR) risk factors in a cohort of 3048 rural children aged 7–12 years from southern Poland. Biological, socio-demographic and lifestyle factors were analysed, and odds ratio and 95% confidence interval were calculated using a logistic regression analysis. The prevalence of abdominal obesity in rural boys and girls in the sample was 11% and 9% respectively. Obesity in both parents, irregular breakfasts, irregular meals during the day and regularly consumed tea were significant factors of abdominal obesity risks in rural girls. Being the only child, low number of people in a household, obesity in both parents, high energy-dense food index and no exercise significantly increased the risk of abdominal obesity in rural boys. The study demonstrated tendencies similar to other European countries in the prevalence of abdominal obesity among sexes. Lifestyle behaviours should be changed and adapted to each sex since risk factors differ between the sexes and indicate higher eco-sensitivity in boys.

Lifestyle risk factors of general and abdominal obesity in students of the school of medicine and health science of the university of development studies, tamale, ghana.

This study evaluated the prevalence of general and abdominal obesity among students of the University for Development Studies, School of Medicine and Health Sciences (UDS-SMHS), Tamale, Ghana. Also, lifestyle risk factors for the two obesity indices were investigated. This study was conducted among a sample of 646 students. Anthropometric measures of weight, height, and waist circumference were appropriately assessed. The prevalence of general and abdominal obesity was 1.9% and 4.2%, respectively. Risk factors of general obesity were being female (crude OR = 6.9, 95% CI = 1.85–25.80, P = 0.0021), engaging in light PA (OR = 12.45, 95% CI = 2.96–52.41, P = 0.0006), being aged 28–37 years (OR = 5.37, 95% CI = 1.39–20.68, P = 0.0329), nonintake of coffee (OR = 4.1, 95% CI = 1.10–15.28, P = 0.0357), being married (OR = 5.7, 95% CI = 1.48–22.02, P = 0.0286), and being abdominally obese (OR = 02.7, 95% CI = 25.61–11.60, P < 0.0001). Risk factors for abdominal obesity were being female, being married, having general obesity, and nonintake of coffee. Abdominal obesity was more prevalent than general obesity. Risk factors included being female, married, and generally obese and nonintake of coffee.
