  1. MH = Mental Health. Infrequent contact includes “rarely” and “a few times a year”. Frequent contact includes “at least every month”, “at least every week” and “every day”. Model adjusts for family structure, socio-economic position, mother’s age at birth of first child, presence of medical condition lasting 6 months or more in child, at least one parent has an ongoing medical condition and child gender, bold type p < .05. Interactions tested but found to be non-significant: mother has MH problem x maternal grandmother/grandfather has MH history; father has MH problem x paternal grandmother/grandfather has MH history; maternal grandmother/grandfather has MH history x contact with maternal grandparents; paternal grandmother/grandfather has MH history x contact with paternal grandparents.
