Childhood growth, current age, and waist circumference predict biological reserve capacity, physical performance, and rapid aging in Bangladeshi women

Background: The UK Bangladeshi community is socially disadvantaged, and many adults suffer from obesity, diabetes, other chronic illnesses. Rapid aging has been noted.
 Objectives: Analyse biosocial trade-offs in growth, adult body composition, reproduction, which are risk factors for age-related decline physical performance, more rapid aging, frailty, death.
 Methods: Sample: 40 mothers (40-70 years old), one of their daughters (N=37, 18-36 old) the United Kingdom (UK), 22 mother-daughter pairs same age range Bangladesh (BD). Measurements: anthropometry, including knee height, migration, demographic history, education level, current menstruation (yes/no), a 7-component lower function score (PFS). Analysis: ridge regression St Nikolas House Analysis (SNHA).
 Results: All women short stature (x̄=150cm), with especially low height. Daughters who migrated to have shorter height than born UK. Marriage was 16-18 total pregnancies ~6 per mother, ~3 daughter. higher fatness PFS BD women. Greater predicts greater PFS, that waist circumference older predict PFS. SNHA finds most direct predictor PFS.
 Conclusion: Adult may serve as sensitive indicator early life emotional well-being factor frailty death. International migration associated poorer health status performance at later ages.
