“…The twenty-three studies included in this review were conducted in high or upper-middle income countries (using the World Bank classification). Of these, 14 were set in Europe [16][17][18][19][20][21][22][23][24][25][26][27][28][29], five in North America [30][31][32][33][34], three in Australia/Oceania [35][36][37], and one study took place in a country in Central America [38] (see Table 2). The studies used various designs, including RCTs (n = 1) [38], cluster randomized trials (n = 3) [25,30,34], quasiexperimental designs (n = 11) [16, 18, 22, 23, 27-29, 33, 35-37], pre-post-tests without control group (n = 3) [17,19,31], and secondary analyses (n = 5) [20,21,23,26,32].…”
