Relationship between self-monitoring of diet and exercise change and subsequent risk factor changes in children and adults.
Self-monitoring is often used in health behaviour change programs; but it is not known to what extent self-monitoring data are valid and useful in predicting changes in cardiovascular disease (CVD) risk. Subjects included 72 Anglo adults, 68 Anglo children, 80 Mexican-American adults and 94 Mexican-American children. Subjects were families with fifth and sixth grade children who participated in an 18-session family-based diet and exercise change program designed to reduce CVD risk. During the intervention, each participant self-monitored diet and aerobic physical activity. Families were measured at baseline, 3, 12, and 24 months. For adults, self-monitored changes in diet correlated with changes in body mass index, systolic blood pressure, total cholesterol and LDL 1 and 2 years later. Correlations between self-monitored diet and diet-related risk factor changes were not observed among children. Correlations between self-monitored exercise and subsequent risk factor changes were not observed among adults. For children, self monitored changes in aerobic physical activity correlated significantly with changes in VO2Max and HDL/LDL ratio 1 and 2 years later. Thus, this study provides some support for the predictive validity of diet self-monitoring in adults and exercise self-monitoring in children.
