Document Summary
Females tend to lose height sooner and at a faster rate: height. Peak height determined by genetic and environmental factors crush onto themselves the spine: those from low economic status have poor nutrition in younger years affecting their potential for growth. Those with high socio-economic status have greater nutrition and therefore greater potential for growth: weight. Females tend to gradually increase weight until the 5th decade, weight then plateaus for a couple of decades, then slowly starts to decrease. Males have similar pattern, but the decline in body weight starts a bit sooner. *unusual or sudden weight loss in elderly may reflect health problems (60+: bmi. Gender difference for when peak bmi occurs: males peak around 45-49 years, females peak around 60-70. Why: women start losing height sooner, and weight stays same or increases, so. *bmi has complex relationship with mortality risk, depending on age. (graph depicts bmi, lowest point is associated with lowest mortality risk)
