||Childhood obesity and lack of physical activity among children and adolescents are national concerns because of their epidemic prevalence. This study examined the correlation between parental physical activity upbringing and current physical activity patterns, adult weight status, and current parenting habits. This investigation is the first study conducted to determine if there is a correlation between a strong, encouraging, physically active upbringing and adult physical activity patterns. Five hundred fifty-eight adults completed the questionnaire. The questionnaire identified general demographics, retrospective analysis of individuals' physical activity upbringing, current physical activity patterns, physical activity parenting habits, and body mass index level. The questionnaire was developed from multiple constructs of social cognitive theory, including reciprocal determinism, observational learning, reinforcement, environment, and behavioral capability. A series of statistical correlations were conducted to determine direction, strength, and significance of the relationships. Analyses showed that a strong physical activity upbringing was characterized by positive role models, rewards, communication, and encouragement. These characteristics promoted participation in vigorous physical activities as adults. No significant correlation was found between physical activity upbringing and participation in moderate walking or sitting activities. A significant correlation revealed that participants who had a strong physical activity upbringing had lower adult body mass index levels. Three hundred seventy-two participants were included in the correlation. Only participants who had children were included in this correlation. Parents who were raised with a strong physical activity upbringing tended to emphasize physical activity when raising their children. A series of additional exploratory analyses were performed. Results from this study show that a strong physical activity upbringing is important in promoting weight maintenance, long-term physical activity patterns, and intergenerational parenting habits. The implications for childhood obesity prevention, health education, and suggestions for future research are discussed.
