Efficacy of school-based interventions aimed at decreasing sugar-sweetened beverage consumption among adolescents: a systematic review

In the citing paper

“According to the JBI critical appraisal tool, 14 reviews scored high [30–32, 34–41, 43–45], two reviews scored moderate [33, 42], and only one review scored low [29] in terms of methodological quality (Table 2).”

In the citing paper

“Majority of the reviews (n = 14) evaluated multi-component interventions [30–32, 34–40, 42–45] while three reviews evaluated only health education interventions [29, 33, 41].”

In the citing paper

“Fifteen of the reviews used narrative synthesis [29–43] and two included both meta-analysis and narrative synthesis [44, 45].”

In the citing paper

“These reviews mostly included studies based in HICs. Eight reviews among these 14 included primary studies based in five LMICs [30, 35–38, 42, 43, 45].”

In the citing paper

“All the reviews included studies based in HICs, and only eight reviews included a few studies based in five LMICs [30, 35–38, 42, 43, 45].”

In the citing paper

“The primary outcomes for these reviews were intake of FV [30, 32, 36–38, 42, 45], processed snacks [30, 36–38, 45], SSB [30, 35, 37], fat [37, 42], protein, fibre and vitamins [37], frequency of regular meals [30, 37, 38], recommended calorie intake [37, 42], healthy eating knowledge [30, 36], and staying in school for having healthy lunch [38].”

In the citing paper

“There were promising effects of multi-component interventions on healthy eating behaviour reported in seven high-quality [30, 32, 35–38, 45] and one moderate-quality reviews [42] (including 192 unique studies) [30, 32, 35–38, 42, 45].”

In the citing paper

“The contents involved lessons on healthy eating [32, 37, 38, 42, 45], food labelling, healthy cooking [30, 36], consequences of SSB intake [35], nutrition, food safety farmers’ visits on healthy food cultivation [36], menu planning, healthy eating goal setting and self-monitoring, healthy food as rewards, and food tasting [38].”

In the citing paper

“The contents involved increased availability of milk and protein [32, 35–38, 45] and fresh fruits [30], free or subsidised FV [35], replacing SSB with healthier alternatives (milk, water, juice) in vending machines [35], chef, staff consultations on healthy culinary lessons [36], and healthy eating posters around school [45].”

In the citing paper

“These reviews mainly focused on interventions in HICs - only 11 primary studies were from LMICs (Ethiopia, India, Iran, Kenya, and Tunisia) [30, 35–38, 42, 45].”

In the citing paper

“The family involvement components at the system level included communicating with families via newsletters [30, 32, 35, 37, 38], leaflets [30, 45], emails [35, 37], booklets [30], brochures [30] and texts [37], organising parents’ meetings [35, 45], in-school learning sessions, food coupons [37] and social support groups [35], and providing parents recipe guides [30].”

In the citing paper

“The contents involved information on healthy eating knowledge [30, 32, 35, 38, 42, 45], healthy cooking, feeding healthy foods to children at home [37], nutritional guidelines [38], coupons to purchase healthy foods [37], offering FV and free healthy foods [45].”

In the citing paper

“The outcomes were measured by FFQ [32, 35–38, 42, 45], 24 h dietary recalls [32, 35–38, 45], food diary [38, 42], knowledge attitude practice (KAP) survey [32, 45], cognitive and attitudinal assessments [38], FV recall, number of days stayed, bought, ate healthy lunch at schools, snack scale [38], and 7-day recall [45], or 5-day food recall [42].”
