aSampling weights were used. Seasonal differences within each area were tested with chi-square test before pooling data from two seasons and significant differences were found for HHS in Quelimane (Jan-Feb: weighted percentage 30%, 27/90, vs May-June: weighted percentage 15%, 13/87; P=.02).
bOverall test (chi-square) of regional differences after pooling data from the two seasons. This test was followed by pairwise tests.
cIn pairwise comparisons, Quelimane differed significantly from Maganja da Costa (P<.001) and from Morrumbala District (P<.001).
