One possible approach is to construct the table as visiting_friends_dpYear * gender and use the DOMAIN=ROW option in PROC SURVEYFREQ to produce domain analysis (of gender) for each level of visiting_friends_dpYear. When you specify DOMAIN=ROW, the CHISQ option produces a one-way chi-square test for each level of the row variable (which compares 'girls 1-10d' with 'boys 1-10d' and so on).
