Effect of a family-based lifestyle intervention on weight reduction among Jordanian children with obesity aged 6-9 years

This study aimed to evaluate the effect of a family-based lifestyle intervention on reducing body weight among Jordanian children with obesity aged 6-9 years old. The pretest-posttest control group design was conducted among 162 children (75 in the intervention group and 87 in the control group) with obesity aged 6-9 years old at four primary schools in Jordan during the period from March 2021 to July 2021. The results found that, after the intervention, there was a statistically significant change in the F scores in the control group vs. in the intervention group ( M = 37.07, SD = 2.77; M = 33.48, SD = 2.73; t (160) = 8.29, P < 0.001), where the mean BMI percentile was reduced by 2.05 in the intervention group. A significant difference was demonstrated in the median BMI percentile in the intervention and control groups post-intervention ( P < 0.001). A significant difference was also noticed between the average weekly reported dietary habits and the physical activities of both the control group and the intervention group post-intervention. The findings support the effect of family-based lifestyle interventions. Healthcare providers should adopt such interventions for children living with obesity. Future study is required to evaluate the long-term effectiveness of this intervention on weight reduction.
