“…9 The students of primary school (public and private) represented the study population from which we derived the sample for this study. The prevalence of obesity in primary schools in Brazzaville is 7.1%, 10 and the sample size (n) was determined using the following formula: n = ( z 2 pq )/ d 2 , where z is the standard normal distribution (1.96), with d error component of interval estimate (0.05), p proportion for the population (0.071), and q = 1 − p (1 − 0.071). Thus, the sample should contain at least 144 participants.…”
