(HealthDay News) — Childhood obesity prevention programs are beneficial for low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C), according to a systematic review and meta-analysis published in the December issue of Obesity Reviews.
Li Cai, from Sun Yat-sen University in China, and colleagues examined the effects of childhood obesity prevention programs on blood lipids in high-income countries. Data were obtained from 17 relevant randomized controlled trials, quasi-experimental studies, and natural experiments that implemented diet and/or physical activity interventions in 2–18-year-olds.
The researchers found that the pooled intervention effect was −0.97mg/dL−1 for total cholesterol (P=0.408); −6.06mg/dL−1 for LDL-C (P=0.018); 1.87mg/dL−1 for HDL-C (P=0.013); and −1.95mg/dL−1 for triglycerides (P=0.202). In 70 % of interventions, there were similar significant or no effects on adiposity and lipid outcomes: Adiposity and lipid outcomes were improved in 15% of interventions, while there were no significant effects on either in 55%.
“Childhood obesity prevention programs had a significant desirable effect on LDL-C and HDL-C,” the authors write. “Assessing lipids outcomes provides additional useful information on obesity prevention program benefits.”
