Document Summary
Study relations between behaviour/psych states/mind (stress) and physical health (and theories) Why study health and behaviour: interesting, demonstrated effect of beh and mind on health. Recent model biopsychosocial model: mind and body linked, bio, psych/social important. Defined 7 health habits (sleep 7-8 hrs, exercise, no smoke) Asked residents to list which behaviours practiced. Also followed up 9 years later (prospective) because wanted no only contemporary results but wondered if habits at time 1 predicted physical health later. Ex 2: sexual behaviour and health (abrahim, 2002) Were asked if they have sex 1,2, or 3 times per week? attack over 10 year period. Sex 3 times per week, as likely to have heart. Some variables can not be experimented upon (ethics) Studied stress and birth order (correlation between the 2) others take on protective role over siblings/parents make them more stressed because they could be more protective) Disadvantage of correlation/surveys no cause and effect (doesn"t tell what causes what)
