Abdominal obesity and associated factors among urban adults in Southwest Ethiopia: a community-based cross-sectional study.

the obesity epidemic is growing faster in developing countries with no exception of Ethiopia. Currently, abdominal obesity is identified as a major risk factor for chronic diseases due to the accumulation of liable fat. However, despite the evidence of certain documented data, abdominal obesity has been on the rise in Ethiopia, especially in urban areas. Therefore, this study aimed to assess the prevalence and factors associated with abdominal obesity among adults in Jimma town, Southwest Ethiopia. a community-based cross-sectional study was employed on 845 adults selected using a multi-stage sampling technique. Data were collected using a pretested interviewer-administered questionnaire. Data were entered using Epi-data version 3.1 and exported to STATA version 14 for analysis. Simple linear regression was conducted to identify candidate variables. A multivariable linear regression model was fitted to identify factors associated with abdominal obesity. P-value<0.05 was used to declare statistical significance. a total of 806 respondents participated in this study, making a response rate of 95.4%. The magnitude of abdominal obesity was found to be 24.6% (95% CI: 21.5, 27.5). Physical activity (β= -2.053; 95%CI: -3.353, -0.454), alcohol consumption (β=1.631; 95%CI: 0.176, 3.087), and age (β=0.319; 95%CI: 0.250, 0.389) were significantly associated with abdominal obesity. the magnitude of abdominal obesity among adults in the study area was high compared to previous studies. Alcohol drinking, being physically inactive, and age were predictors of abdominal obesity. There is a need for intervention for adults with physical inactivity and alcohol consumption to reduce abdominal obesity.

Incorporating the American College of Cardiology/American Heart Association hypertension diagnostic criteria into metabolic syndrome criteria will significantly increase the prevalence of metabolic syndrome among college students

The purpose of this study was to examine the impact that the revised American College of Cardiology/American Heart Association (ACC/AHA) hypertension diagnostic criteria would have on the prevalence of metabolic syndrome (MBS) among college students. Students completed an objective health assessment between September 2015 and April 2018 that involved the assessment of abdominal girth, blood glucose, lipids, and blood pressure (BP). Data of 5681 students (60.1% Men; 21 ± 1 years) who had all MBS risk factors assessed were analyzed to compare differences between old and new diagnostic criteria and identify which component of BP best predicts metabolic risk factors. The prevalence of MBS increased by 40.6% and 104.5% with the change to ACC/AHA criteria from the AHA/National Heart Lung and Blood Institute and theSeventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High BP criteria, respectively. The greatest relative increase in the prevalence of MBS was observed among women. Systolic BP and diastolic BP were significant predictors of abdominal obesity, and diastolic BP was a significant predictor of elevated triglycerides. Changes in hypertension diagnostic criteria had a significant impact on MBS prevalence. This is positive as it will allow earlier identification of young adults at risk of developing various noncommunicable diseases, but the ability of colleges to identify and then intervene to improve the health of at-risk students remains unclear. Furthermore, findings indicate that BP may hold utility as a cost-effective predictor of certain metabolicrisk factors in the absence of efficient, accurate, and affordable alternatives.

Longitudinal relationships between changes in body composition and changes in selected metabolic risk factors (abdominal obesity and blood pressure) among South African adolescents.

BackgroundIncidence of childhood high blood pressure (BP) is increasing worldwide. This study examined the longitudinal relationship between changes in body composition (i.e. body mass index (BMI), waist circumference (WC) and percentage body fat) and selected metabolic risk factors (abdominal obesity and BP) among adolescents from the Tlokwe municipality in the North West Province of South Africa.MethodOne hundred and eight-six adolescents (81 boys and 105 girls) aged 14 to 16 years participated in the study. Body composition was measured following the International Society of the Advancement of Kinanthropometry standard procedures. BMI, abdominal obesity using WC measurement, and resting BP were determined. Analysis of variance (ANOVA) for repeated measures was calculated to determine changes in anthropometric measures and body composition as well as changes in BP. Additionally, Univariate analysis of variance with repeated measures and participants as a random sample was applied. Diastolic BP (DBP) and systolic BP (SBP) were used as dependent variables and sex, age, BMI, WC, and waist-to-height ratio as independent variables.ResultsSignificant changes were found for stature, BMI, body mass, WC, SBP, and DBP. BMI for the total group was significant and positively related to abdominal obesity in 2012 (r = 0.55; p < 0.01) and in 2013 (r = 0.77; p < 0.01) and to SBP (r = 0.26; p < 0.05) in 2012 and (r = 0.17; p = 0.43) in 2013. BMI among the boys was significantly and positively related to abdominal obesity in 2012 (r = 0.83; p < 0.01) and 2013 (r = 0.91; p < 0.01). For the girls, BMI was significantly and positively related to abdominal obesity (r = 0.49; p < 0.01) and to SBP (r = 0.32; p = 0.05) in 2012. Boys with a higher WC in 2012 had significantly increased DBP (p < 0.05). Boys measured in 2012 with greater WC and BMI show a significant increase in SBP.ConclusionsBMI was positively related to BP and abdominal obesity over time. Relatively high BMI and abdominal obesity significantly increased the likelihood of elevated BP over time, especially in boys. BMI was a predictor of abdominal obesity in boys, while in girls, BMI was a predictor of both abdominal obesity and SBP. In view of the future health implications of both abdominal obesity and elevated BP, urgent strategic interventions programs aimed at increasing physical activity and advocating for well-balanced dietary practices as well as importance of keeping normal blood pressure among South African adolescents are needed.

P115 Determination of waist circumference and correlation of waist-to-height ratio in adolescents as a prediction tool of high blood pressure

Abstract Introduction The obesity and overweight epidemic, together with increasing cardiovascular disease, represent a major health problem worldwide, and their occurrence in childhood and adolescence has increased in recent time. Purpose to assess the association of waist circumference (WC) and waist-to-height ratio (WHtR) coefficient with occurrence rate in adolescents with high blood pressure. Materials and methods The results of a single-step cross-sectional study of teenagers aged 12-13 years studied in 12 secondary schools in our city (Kazakhstan) are presented. The study included adolescents in the amount of 1519 (average age, standard deviation 12.3 + 0.46 years). For representing the outcomes there were used the measurement of weight, height, BMI, WC, WHtR and the blood pressure of adolescents. Criteria for BP: normal BP (SBP and DBP &amp;lt;89th percentile); high normal BP (SBP and DBP ≤90 and 94th percentile); arterial hypertension (SBP and DBP &amp;gt; 95th percentile). ROC analysis was used to study the relationship between WC, WHtR and BMI. The distinctive impact of WC or WHtR on the development of these states was expressed as the area under the curve (AUC 95% CI). Results From 1519 studied teenagers of 12-13 years, boys were 49.1% (n = 745), girls 50.9% (n = 774). Population with normal BP composed 62.7%, normal raised BP - 24.8%, hypertension - 12.4%, WC˂90th percentile at 98.5% (n = 939). The distribution by sex was: girls are more likely to have abdominal obesity than boys, (χ²=19.940, df = 1, р˂0.001). An elevated level of WHtR was detected in 7.6% (n = 115) of adolescents. Among boys were 7.7% (n = 57) and girls 7.5% (n = 58), χ²=0.013, df = 1, p = 0.908. ). Girls (10.8%) with high blood pressure have increase WC than boys (2.1%), χ²=26.689, df = 1, р˂0.001. Adolescents with high blood pressure have enhanced WHtR - 12.2% than adolescents with normal blood pressure (2.7%), χ²=27.518, df = 1, р˂0.001. Increase of WC &amp;gt; 90th percentile enhances with 4.5 times (95% CI: 2.44-8.53) and WHtR with 2.7 times (95% CI: 1.85-4.04) in adolescents with high blood pressure. WC (AUC = 832; 95% CI: 0.792-0.872) and WHtR (AUC = 0.812; 95% CI: 0.770-0.854was a better predictor of abdominal obesity than BMI. Conclusions. Indicators of WC, WHtR indicating to the presence of abdominal obesity to identify risk factors for the development of high blood pressure. Participants with increase of WC &amp;gt; 90th percentile were 4.5 times and WHtR were 2.7 times more likely to have high blood pressure.

A17075 The two-year longitudinal relationships between changes in body composition and changes in selected metabolic risk factors (abdominal obesity and blood pressure) among adolescents from Potchefstroom in the North West Province of South Africa

Objectives: To determine the longitudinal relationship between changes in body composition and selected metabolic risk factors (abdominal obesity and BP) among adolescents from the Tlokwe Municipality in the North West Province of South Africa Methods: 289 adolescent boys and girls aged 14.9 ± 0.76 years participated in the study. Body composition was measured following the International Society of the Advancement of Kinanthropometry (ISAK) standard procedures. Abdominal obesity was determined using the waist circumference measurements (WC) measurements and resting BP was determined by Omron MIT Elite Plus. Results: Significant mean changes were found for stature, body mass index (BMI), body mass, WC, systolic (SBP) and diastolic blood pressure (DBP) over the measurements period (p < 0.05). Pre-hypertension increased by 5% for the total group (from 5% in 2011 to 10% in 2013) with boys having higher percentage scores of 14% in 2012 (compared to 5% for girls) and 18% (compared to 4% in girls) in 2013. Overweight increased (5%) from 13% to 18% for the total group, with girls being more overweight (9%) compared to the boys (1.9%). BMI for the group was significantly related to WC (p = 0.01) and SBP (p < 0.05). BMI among the boys, was significantly related to abdominal obesity (p < 0.01) and positively but non-significantly related to BP. In girls, BMI was significantly related to WC. (p < 0.01) and systolic blood pressure (SBP) in 2012 (p = 0.05). Conclusion: Overweight (among the girls), BP and abdominal obesity (among the boys) are on the rise among the adolescents. BMI is significantly related to selected metabolic risk factors (BP and abdominal obesity). BMI is predictor of abdominal obesity in boys while in girls, BMI is a predictor of both WC and are SBP.

Study on correlation of abdominal height with visceral fat area and the cutoff points to predict abdominal adiposity

Totally 177 individuals (87 males and 90 females), who took abdominal computer tomography were enrolled. Anthropometric surrogates such as abdominal height(AH), waist circumference(WC), body mass index(BMI), and waist to height ratio(WHtR) were measured. Correlations between AH, WC, BMI, and WHtR with visceral abdominal fat were analyzed, and receiver operating characteristic curves(ROC)were prepared for detecting abdominal adiposity at or beyond 80cm2 using lumbar vertebra 4-5 cross-section visceral fat areas as the screening cut-point within gender separately. Youden's index was used to determine cut-off values of AH, WC, BMI, and WHtR by which to classify excess abdominal fat. 70(80.5%) males and 59(65.9%) females had abdominal obesity. Compared to other anthropometic indicators, AH presented the highest correlation with visceral adipose fat. The pearson correlation efficiencies were 0.825 and 0.732, the cut-off points were 20 cm and 20.3 cm in male and female respectively. After controlling for age, receiver operating characteristic analysis showed that AH, followed by WHtR, outperformed WC and BMI in identifying central obesity participants. Optimal cut-off values of the physical anthropometric indices to indentify abdominal adiposity were 20 cm(AH), and 91 cm(WC) 25 kg/m2(BMI), and 0.52(WHtR) for men, and 20.3 cm(AH), 86.5 cm(WC), 25 kg/m2(BMI), and 0.54(WHtR) for women. AH is effective for predicting visceral adiposity and might be considered the best predictor of abdominal obesity at a cut-point of 20cm in Chinese adults.

Predictors of Abdominal Obesity among Adult Nigerians in a Resource-poor Environment of a Rural Hospital in Eastern Nigeria

Background: Abdominal obesity once considered an aesthetic rather than a pathological condition is now recognized as a principal risk factor for metabolic syndrome and magnifies the risk of cardiovascular diseases. As the case detection rate of abdominal obesity increases in Nigeria determining its predictors remain relevant for proactive control intervention.

Low-grade inflammation and depressive symptoms as predictors of abdominal obesity

Abundant evidence suggests that depression is a risk factor for cardiovascular disease and metabolic syndrome. Systemic low-grade inflammation and evolving abdominal obesity are hypothesised to be underlying mechanisms explaining the relationship. To test this hypothesis we examined the association of depressive symptoms and inflammation in developing abdominal obesity. The subjects were 726 non-diabetic men, 42-60 of age at baseline, participating in the Kuopio Ischemic Heart Disease Risk Factor Study. The follow-up data was collected 11 years after the baseline. Low-grade inflammation was defined as serum C-reactive protein ≥2 mg/l and depressive symptoms were assessed by the Human Population Laboratory Depression Scale. Incident abdominal obesity was defined as waist girth >102 cm. Men with low-grade inflammation and depressive symptoms were more likely (OR 4.28, 95% CI 1.93-12.01) to develop abdominal obesity during the 11-year follow-up than in men not having either of these conditions, adjusting for age, smoking, alcohol consumption, prevalent cardiovascular disease, physical activity and socioeconomic status. These men were also more likely (OR 3.94, 95% CI 1.38-11.26) to develop metabolic syndrome. The presence of systemic low-grade inflammation together with depressive symptoms seems to detect men at a particularly high risk of developing abdominal obesity over a long period of time.

Predictors of abdominal obesity and high susceptibility of cardiometabolic risk to its increments among Turkish women: a prospective population-based study

To investigate determinants of abdominal obesity and its metabolic and clinical consequences relative to its degree in women, a prospective evaluation of 1682 female participants (aged 28-79 years at baseline), representative of Turkey's women, was performed. For components of metabolic syndrome (MS), criteria of National Cholesterol Education Program guidelines were adopted, modified for cut point of 91 cm or greater for abdominal obesity and less than 45 mg/dL for low high-density lipoprotein (HDL) cholesterol. Fasting insulin and C-reactive protein concentrations and (inversely) smoking more than 10 cigarettes daily were significant predictors of newly developed abdominal obesity at a follow-up of mean 5.9 years. In the prediction of high triglyceride–low HDL dyslipidemia, elevated blood pressure (BP) or MS and doubling of baseline fasting insulin level contributed approximately 25% to the hazard ratio (HR), whereas waist circumference exhibited independent HRs of 1.30, 1.62, and 2.22, respectively. Waist girth (or body mass index) quartiles was the major predictor (HR, 1.72) of diabetes mellitus (DM), followed by physical inactivity and total cholesterol and insulin levels, all independent of each other. Waist girth quartiles in women conferred excess risk of incident coronary heart disease from quartile II onward, independent of age, DM, and elevated BP. Fasting insulin and C-reactive protein levels and (inversely) heavy smoking are main predictors in Turkish women of abdominal obesity. Across waist girth quartiles, multiadjusted relative risks for dyslipidemia, elevated BP, MS, and coronary heart disease rise sharply and asymptotically from quartile II (≥83 cm) onward, whereas risk of DM emerges in the top quartile. A waist girth of 83 cm or greater should be regarded as abdominal obesity among Turkish women.
