The Tromsø Survey: the Family Intervention study--the effect of intervention on some coronary risk factors and dietary habits, a 6-year follow-up.
While most intervention studies on coronary heart disease have focused on the high-risk person only , the present study used the family as the unit of intervention . In the study 1373 high-risk men , ages 30 - 54 years , were identified on the basis of high total cholesterol ( TC ) and /or low relative high-density lipoprotein cholesterol ( HDL-C ) ( HDL-C/TC ) following the 1979/1980 survey in Tromsø . The men and their families were r and omly allocated to a control or intervention condition . The intervention families were given advice on diet , smoking , and exercise . At rescreening in 1986/1987 , significantly lower risk factor levels were found in both the intervention men and their spouses compared with those in the control group . For children , the differences were small and mostly nonsignificant . Men , spouses , and children in the intervention group reported more favorable dietary habits than those in the control group . No differences were found in smoking or leisure time physical activity
