Introduction: Central obesity (CO) leads to increased cardiovascular and metabolic risks in children and adolescents. The evidence on prevalence of central obesity and its correlates are lacking among adolescents in India.
Objectives: (1) To estimate the prevalence of central obesity in school-going adolescents, (2) To determine the association between central obesity and generalized obesity (GO) among adolescents, and (3) To determine the correlates of central obesity.
Methods: Totally, 660 adolescents, selected using systematic random sampling, in four urban schools in Aligarh were interviewed using pre-designed questionnaire and Global Physical Activity Questionnaire. Height, weight, and waist circumference (WC) were measured. Body mass index (BMI) was calculated. CO was defined as >90 age-and-sex-specific percentile of WC and GO by BMI-for-age-and-sex percentiles given by WHO Growth Reference 2007. Chi-square test and logistic regression analysis were done using IBM SPSS version 20.0.
Results: Overall prevalence of central obesity was found to be 28.5% [CI: 25.2-32.0], almost double of generalized obesity (14.6%, 95%CI: 12.1-17.6). The prevalence was significantly higher among girls (33.6%, 95%CI: 28.3-39.3) than in boys (24.7%, 95%CI: 20.7-29.3) and in the affluent group (38.8%, 95%CI: 33.7-44.1) than in non-affluent (18.2%, 95%CI: 14.4-22.7). More than 1/4 of normal weight adolescents [27.2% (99/364)] also had CO. Increased fast food intake (OR: 4.1; 95% CI = 2.1-8.1), low Physical Activity Level (OR: 2.4; 95% CI = 1.3-4.3) and more than 10 hours sedentary time spent per day (OR: 2.2; 95% CI = 1.1-4.8) were independent determinants of CO.
Conclusion: Central obesity among school-going adolescents of a non-metropolitan Indian city is alarmingly high and a burden even in one-fourth of normal weight adolescents. Screening for CO among adolescents by primary physicians, pediatricians, and through School Health Programme is recommended. Behavior change communication regarding risk factors for CO is advocated.

Background: Acceptance and commitment therapy provides a psychobehavioral framework feasible for digital and hybrid weight loss interventions. In face-to-face studies, group-based interventions yield more favorable outcomes than individual interventions, but the effect of the intervention form has not been studied in combination with eHealth.
Objective: This study investigated whether a minimal, 3-session group or individual enhancement could provide additional benefits compared to an eHealth-only intervention when assessing weight, body composition, and laboratory metrics in a sample of occupational health patients with obesity.

Background: The cerebellum is one of the major central nervous structures consistently altered in obesity. Its role in higher cognitive function, parts of which are affected by obesity, is mediated through projections to and from the cerebral cortex. We therefore investigated the relationship between body mass index (BMI) and cerebellocerebral connectivity.

Importance: Epidemiological studies suggest that lifestyle factors are associated with risk of dementia. However, few studies have examined the association of diet and waist to hip ratio (WHR) with hippocampus connectivity and cognitive health.
Objective: To ascertain how longitudinal changes in diet quality and WHR during midlife are associated with hippocampal connectivity and cognitive function in later life.

Self-reported physical activity is associated with lower brain food cue responsiveness in reward-related regions, but relationships utilizing objective physical activity measurement tools have not been explored. This cross-sectional study examined whether device-measured moderate-to-vigorous intensity physical activity and sedentary time are related to neural responses to visual food cues using functional magnetic resonance imaging. Fifty-one healthy adults (30 men, 21 women; mean ± SD: age 26 ± 6 years; body mass index 24.
