Obesity In Children

Abstract Objectives Sugars have been implicated in the epidemic of obesity. It is unclear whether food sources of fructose-containing sugars other than sugar-sweetened beverages (SSBs) are associated with increased risk of obesity. To assess the evidence of the relation of food sources of fructose-containing sugars with incident overweight or obesity, we undertook a systematic review and meta-analysis of prospective cohort studies. Methods We searched MEDLINE, EMBASE and Cochrane Library through Aug 2019. We included prospective cohort studies of ≥1 year. Two reviewers extracted data and assessed the risk of bias. The primary outcome was incident overweight/obesity. Data were pooled using generic-inverse variance method (random effects) and expressed as relative risks (RR) for incident outcomes and ß-coefficients for WC with 95% confidence intervals (CI). GRADE assessed the certainty of evidence Results We included 12 and 8 prospective cohorts involving 181,295 adults and 31,717 children, respectively. Four food sources of fructose-containing sugars were identified: SSBs, 100% fruit juice, fruit and yogurt. There was no data available in children for yogurt or WC. SSBs were associated with increased incident overweight/obesity in children (RR, 1.22 [95% CI, 1.03 to 1.44] but not in adults and increased incident abdominal obesity in both children (3.78 [1.08 to 13.25]) and adults (1.51 [1.11 to 2.06]), but there was no association with change in WC in adults. Fruit juice was associated with increased incident overweight/obesity in children (1.28 [1.07 to 1.53]) but not in adults, and there was no association with incident abdominal obesity in either children or adults or WC in adults. Fruit was associated with decreased incident overweight/obesity (0.87 [0.82 to 0.92]) and decreased WC (ß, −0.23 cm [−0.33 to −0.13]) in adults. Yogurt was associated with decreased incident abdominal obesity (0.65 [0.47 to 0.90]) in adults with no data available on WC. The certainty of the evidence was graded as “very low” to “moderate”. Conclusions Current evidence indicates that the relation between fructose-containing sugars and obesity outcomes differs by food sources. More research of more food sources of sugars is needed to improve our certainty in the evidence.

Abstract Objectives Sugars have been implicated in the epidemic of obesity. It is unclear whether food sources of fructose-containing sugars other than sugar-sweetened beverages (SSBs) are associated with increased risk of obesity. To assess the evidence of the relation of food sources of fructose-containing sugars with incident overweight or obesity, we undertook a systematic review and meta-analysis of prospective cohort studies. Methods We searched MEDLINE, EMBASE and Cochrane Library through Oct 2018. We included prospective cohort studies of ≥1 year. Two reviewers extracted data and assessed the risk of bias (Newcastle-Ottawa Scale). The primary outcome was incident overweight/obesity. Data were pooled using generic-inverse variance method with random effects model and expressed as relative risks (RR) with 95% confidence intervals (CI). GRADE assessed the certainty of evidence. Results We included 20 prospective cohort studies: 9 (n = 25,422; 2614 events) and 6 (n = 119,137; 24,123 events) of incident overweight/obesity and 1 (n = 424; 47 events) and 7 (n = 29,166; 4255 events) of incident abdominal obesity in children and adults, respectively. Three food sources of fructose-containing sugars were identified: SSBs, fruit juice, and yogurt. SSBs were associated with increased incident overweight/obesity in children (RR, 1.22 [95% CI, 1.03 to 1.44] but not in adults and increased incident abdominal obesity in both children (3.78 [1.08 to 13.25]) and adults (1.51 [1.11 to 2.06]). Fruit juice was associated with increased incident overweight/obesity in children (1.28 [1.07 to 1.53]) but not in adults, and there was no association with incident abdominal obesity in either children or adults. Yogurt was associated with decreased incident abdominal obesity (0.65 [0.47 to 0.90]) in adults with no data available for any outcome in children. The certainty of the evidence was graded as very low to low. Conclusions Current evidence indicates that the relation between fructose-containing sugars and obesity outcomes differs by food sources. Further research of different food sources of sugars is needed to improve our certainty in the evidence.
