“…Abdominal obesity in men was defined as measurements of WC $94 cm and WHR $0.9, respectively, and for women measurements of $80 cm and $0.85, respectively. 23,24 Measures of central obesity (WC and WHR) were included in this study as BMI does not quantify body composition or fat distribution. WC and WHR quantify central obesity and provide an indication of visceral fat distribution.…”

Background: Obesity is increasing worldwide including in people living with HIV (PLWH). Antiretroviral pharmacokinetic data in obesity are limited.Objectives: To measure antiretroviral drug concentrations in obese and nonobese PLWH treated with the fixed-dose combination of efavirenz-tenofovir-emtricitabine. To determine pharmacokinetic differences across indicators of obesity and their associated immunovirological outcomes. Methods:We conducted a cross-sectional sample analysis of 2 cohort studies. We measured mid-dose efavirenz, 8-hydroxy-efavirenz, tenofovir, and emtricitabine concentrations. Antiretroviral drug concentrations were analyzed by body mass index (BMI), waist circumference (WC), and waist-to-hip ratio (WHR). Results:We performed a study of 213 participants: General obesity was detected in 20.4% using BMI and abdominal obesity in 53.6% using WC and 62.4% using WHR, respectively. The median concentrations of all antiretroviral drugs were lower among obese participants determined by BMI and WC, with efavirenz showing greater differences than tenofovir or emtricitabine. For BMI, results were most striking for efavirenz (1752.3 vs 2342.9 ng/mL, P = 0.002) with lower concentrations in obese participants. Using WC, efavirenz (1845.8 vs 2571.2 ng/mL, P , 0.001), tenofovir (65.8 vs 73.2 ng/mL, P = 0.036), and emtricitabine (159.5 vs 221.0 ng/mL, P = 0.005) concentrations were lower in obese participants. Eight-hydroxyefavirenz concentrations were similar in nonobese and obese participants for WC. Using WHR, the concentrations of all antiretroviral drugs were lower in the obese population, most strikingly for emtricitabine (173.5 vs 229.0 ng/mL, P = 0.015). There were no immunovirological associations. Conclusion:We found lower antiretroviral concentrations in all obese groups, most strikingly in participants with abdominal obesity determined by WC. Lower drug concentrations had no immunovirological associations.

“…WC was measured to the nearest 0.1cm, between the lower rib and iliac crest, using an inflexible tape meter. The HC is measured using a nonelastic tape measure held horizontally at the point that gives the maximum diameter over the buttocks without constricting it 16 . The BAI was calculated using the below formula: BAI= (HC (cm)/(height 1.5 (m))‐18).…”

The inverse association of body adiposity index and bone health in the older adults: A report from a developing country

The ageing process is associated with the development of different diseases and changes in body composition such as the reduction in fat-free mass (FFM) and/or increase in fat mass (FM). 1 These changes have been referred to as sarcopenic obesity (SO) that is a complex condition with important health care cost implications. 2 Decreased bone mass and bone tissue deterioration during ageing results in osteoporosis. 3 A key determinant of adult skeletal health is acquiring a high bone mass during childhood and adolescence, 4 and the risk of osteoporotic fractures may be decreased by 50% by it. 5 A major predictor for bone mineral content (BMC) and bone accumulation is the lean mass 6 during puberty. 7,8 Although the lean mass (LM) role in bone formation is well known, the relationship between FM and bone mass and bone formation are not well understood. Furthermore, the effect of overweight and obesity on bone health is unknown. 9 Both body weight and LM are greater in overweight and obese people that result in an extra load on the skeleton and higher tensile forces

“…However, BMI cannot distinguish between fat mass and fat-free mass and high BMI does not necessarily reflect increased adiposity [4]. Waist circumference (WC) and waist-to-height ratio (WHtR) provide relevant information on fat distribution and show the degree of abdominal obesity [5,6]. Evidence revealed that abdominal obesity is a better predictor of the presence of cardiometabolic risk factors than obesity evaluated by means of BMI [7].…”

Combined Body Mass Index and Waist-to-Height Ratio and Its Association with Lifestyle and Health Factors among Spanish Children: The PASOS Study

et al. 2022

Background and Aims: The World Health Organization recommended simultaneous measurement of body mass index (BMI) and waist circumference (WC) and suggested joint use to predict disease risks. The aim of this study was to assess the prevalence of BMI and waist-to-height ratio (WHtR) categories among Spanish children and adolescents, as well as their associations with several lifestyle factors. Methods: Cross-sectional analysis of 8–16-year-old children and adolescents (n = 3772) were included in the PASOS nationwide representative study. Children/adolescents and their mothers/female caregivers answered a questionnaire on lifestyle and health factors. Child/adolescent anthropometrics were measured. Four combined BMI-WHtR disease risk categories were built. Results: A third of participants showed combined BMI-WHtR categories with high disease risk (12.3% ‘increased risk’, 9.7% ‘high risk’, 14.3% ‘very high risk’). Participants in the ‘very high risk’ group were less likely to be females (odds ratio 0.63; 95% CI: 0.52–0.76) and adolescents (0.60; 95% CI: 0.49–0.72), to practice ≥60 min/day of moderate-vigorous physical activity (MVPA) (0.73; 95% CI: 0.57–0.93), and to watch <120 min/day of total screen time on weekdays (0.61; 95% CI: 0.49–0.76). Mothers of participants in the ‘very high risk’ group were less likely to have a high educational level, be in the overweight or normal range, have never smoked or were former smokers, and watch <120 min/day of total screen time on weekends. Participants in the ‘increased’ and ‘high risk’ categories had mothers with normal weight and ≥60 min/day of MVPA. Participants in the ’high risk’ group did not achieve ≥60 min/day of MVPA and showed lower adherence to the Mediterranean diet. Conclusions: Adherence to a healthy lifestyle in children and adolescents, but also in their mothers/female caregivers during offspring’s childhood and adolescence, is associated with low BMI-WHtR disease risk.
