Increased food intake, decreased physical activity, and increased alcohol consumption contributes to the freshman 15. Genes account for 50-90% of variation in body weight. Body type, metabolism, and other physiological processes that contribute to body weight and size are influenced by genetic factors. Body mass index (bmi) is a statistic commonly used to estimating a healthy body weight given a(cid:374) i(cid:374)di(cid:448)idual"s height.

Psychosocial influences on health: poverty and discrimination. Problems are magnified by stress: family and social environment, social contagion. The often subtle, unintentional spreading of a behaviour as a result of social interactions.
