Body mass index adjustments to increase the validity of body fatness assessment in UK Black African and South Asian children

(1) Background: Scotland has one of the highest rates of obesity in the Western World, it is well established that poor weight profiles, and particularly abdominal obesity, is strongly associated with Type II diabetes and cardiovascular diseases. Whether these associations are apparent in ethnic population groups in Scotland is unclear. The purpose of this study was to examine the associations between different measures of fatness with clustered cardio metabolic risk factors between Scottish South Asian adolescents and Scottish Caucasian adolescents; (2) Methods: A sample of 208 Caucasian adolescents and 52 South Asian adolescents participated in this study. Stature, waist circumference, body mass index, blood pressure, physical activity, and cardiovascular disease (CVD) risk were measured; (3) Results: Significant, partial correlations in the South Asian cohort between body mass index (BMI) and individual risk factors were generally moderate. However, correlations between Waist circumference (WC) and individual risk factors were significant and strong. In the Caucasian cohort, a significant yet weak correlation between WC and total cholesterol (TG) was noted although no other associations were evident for either WC or BMI. Multiple regression analysis revealed that both BMI and WC were positively associated with CCR (p < 0.01) in the South Asian group and with the additional adjustment of either WC or BMI, the independent associations with clustered cardio-metabolic risk (CCR) remained significant (p < 0.005); (4) Conclusions: No positive relationships were found between BMI, WC, and CCR in the Caucasian group. Strong and significant associations between measures of fatness and metabolic risk were evident in Scottish South Asian adolescents.

Living With Hiv

People living with HIV are surviving longer on successful antiretroviral therapy and obesity rates are increasing. We sought to determine the prevalence of being overweight or obese in a regional population of people living with HIV and to explore the demographic and clinical characteristics associated with obesity or being overweight. Data on patients attending three Northeast England clinics were collected including body mass index and demographics. The prevalence of being overweight (body mass index ≥ 25 kg/m2) or obese (body mass index ≥ 30 kg/m2) was determined and compared with regional population data. Associations between being overweight or obese and demographic and other data were further explored using logistic regression models. In 560 patients studied (median age 45 years, 26% Black-African and 69% male), 65% were overweight/obese and 26% obese, which is similar to the local population. However, 83% and 48% of Black-African women were overweight/obese or obese, respectively, with 11% being morbidly obese (body mass index > 40 kg/m2). In the multivariate analyses, the only factors significantly associated with obesity were Black-African race (adjusted odds ratio 2.78, 95% confidence interval 1.60–4.85) and type 2 diabetes (adjusted odds ratio 4.23, 95% confidence interval 1.81–9.91). Levels of obesity and overweight in people living with HIV are now comparable to the levels in the local population of Northeast England; however, the prevalence is significantly higher in Black-African women. Given the additional risk factors for cardiovascular disease inherent in people living with HIV, better strategies to prevent, identify and manage obesity in this population are needed.
