Influence of Parental Physical Activity and Screen Time on the BMI of Adult Offspring in a Saudi Population.

Saudi Arabia is witnessing a drastic rise in adult obesity. Geographic limitations hamper somatic activities to counter this rise. Parental physical inactivity in the region has never been addressed. This study's purpose is to determine the differences between parent and adult child (the subjects here) levels of physical activity (PA) and screen time (ST) between normal weight and obese adults in the Saudi Arabian population. Two hundred and forty adult subjects (18 to 35 years) were screened for their body mass index (BMI) values (18.5 ≤ 25 as normal and 25 ≤ 30) or above as overweight/obese), followed by their congregation into normal weight (N) ( = 150) and overweight/obese (Ov/Ob) ( = 90) groups. A self-reported questionnaire assessed parenting practices, while a physical activity record diary calculated existing levels of PA and ST. Statistical significance was determined by a chi-squared test ( < 0.01) and BMI correlation was found by Pearson's correlation coefficient. Maternal age (87.8% ≤ 20 years in the Ov/Ob group (Gp) and consanguineous marriage (88.9% in the Ov/Ob Gp) showed significant differences. A high prevalence of inactivity was observed among families (father 53.3%, mother 53.3%, subject 80.0%) in the Ov/Ob Gp. Higher amounts of ST (76.7% ≥ 9 h/day) were found in the Ov/Ob Gp, which significantly differed. Differences in the parent and child levels of PA and ST exist between normal weight and obese Saudi Arabian adults. Physically active parents having adult children inspire them to develop healthy physical behaviors which counter the development of obesity. Consanguineous marriage and early maternal age may be associated with progressive adult obesity.
