Aims: This longitudinal study evaluated the association between childhood family structure and health-related quality of life (HRQoL) at middle age.
Methods: The data on childhood family structure at the age of 14 years ('two-parent family', 'one parent not living at home/no information on father' and 'father or mother deceased') and HRQoL (measured by 15D (15-dimensional)) at the age of 46 were collected from the Northern Finland Birth Cohort 1966 using postal questionnaires. We used the binary logistic regression model to estimate the associations between childhood family structures and the lowest 15D quartile (reference: all other quartiles). The associations were adjusted for offspring mothers' factors during pregnancy (mothers' educational and occupational status).
Results: Of the 6375 participants, the offspring belonging to the 'one parent not living at home/no information on father' family structure subgroup had higher odds ratio of belonging to the lowest 15D quartile than the offspring of 'two-parent families' (adjusted odds ratio (OR) 1.76, 95% confidence interval (CI) 1.31-2.36, p<0.001 for females; adjusted OR 1.86, 95% CI 1.28-2.70, p=0.001 for males). There were no statistically significant associations between the 'father or mother deceased' subgroup and the lowest 15D quartile among the offspring.
Conclusions: A single-parent family origin (due to reasons other than parental death) in childhood was significantly associated with impaired HRQoL at middle age. These results provide new perspectives for understanding the long-standing associations on living in a single-parent family.

Aims: To explore whether a family-based intervention with playful activities among overweight and obese Norwegian children promoted moderate to vigorous and light physical activity compared with a waiting list control group, and to examine whether gross motor competence, isometric body mass index and motivational factors, as reported by the children and their parents, could explain changes observed during a six-month observation.
Methods: A non-randomized cluster-controlled trial with 131 participants, 76 in the intervention group. Participants were aged 6-12 years, and 55 were boys. We performed linear regressions to compare the intervention and the control groups and adjusted linear models to examine predictors for outcomes with the groups merged into one cohort.
Results: We could not demonstrate any intervention effect from the family-based activities. Moderate to vigorous physical activity levels were satisfactory at the start and were maintained during the observation period. None of the predictors could explain outcome status at six months, nor residual change of moderate to vigorous physical activity during the observation. We revealed that parental educational attainment, parental autonomous motivation and the participants' experience of social support impacted light physical activity negatively after six months. Parental education also impacted the residual change of light physical activity negatively during the observation.
