Test of differences in proportions on lifejacket wear among occupational boaters on Lake Albert, Uganda
We conducted a test of differences in proportions of lifejacket wear to assess the effect of the peer-led training among occupational boaters. At baseline, self-reported lifejacket wear between the non-intervention and intervention arm was not significantly different (30.8%– 29.9% = 0.9%, p-value 0.743), indicating that both arms were comparable at baseline based on this variable, hence justifying the randomization. This was similar for observed lifejacket wear (1.0%– 0.6% = 0.4%, p-value 0.807). However, at endline, both self-reported and observed lifejacket wear were statistically different. Self-reported lifejacket wear was significantly higher in the intervention arm than in the non-intervention arm (65.1%– 43.2% = 21.9%, p-value <0.001). Observed lifejacket wear in the intervention arm was significantly different from that in the non-intervention arm (26.8%– 8.8% = 18, p-value <0.001),
