Data from a randomly selected sample of 840 Ontario students were used
to examine factors that affect self-rated physical health. Analyses f
ocused on demographics, family structure, family financial situation,
child-parent relationship, school achievement, self-esteem, alcohol, t
obacco and cannabis use as factors which directly and indirectly influ
ence self-rated health. Specifically, higher income, good child-parent
relationship, higher interest and achievement in school, high self-es
teem, not smoking, and being male were all positively and directly ass
ociated with higher self-ratings of health. Family structure was media
ted by income, and school achievement and child-parent relationship we
re mediated by tobacco use and self-esteem. Our analyses suggest that
student perceptions of physical health are affected by demographic, ec
onomic, social, psychological and competency factors. (C) 1998 The Ass
