    Abstract:
    INTRODUCTION: Maternal obesity has long-term consequences for the offspring's later health, including an increased risk of type 2 diabetes and cardiovascular disease. The underlying mechanisms explaining these associations are, however, not fully understood. METHODS: A total of 2003 individuals from the Helsinki Birth Cohort Study born 1934-44, underwent measurements of body size, body composition, and clinical characteristics at a mean age of 62 years. Data on maternal anthropometry were available from hospital records. RESULTS: Maternal BMI was positively associated with BMI in the offspring. Higher maternal BMI was associated with less favorable body composition in the offspring. There was a significant interaction between birth weight and maternal BMI on offspring body fat percentage (P for interaction 0.003). In mothers with low BMI, a higher offspring birth weight was associated with lower fat percentage, while among those with maternal BMI in the highest fourth, higher offspring birth weight predicted higher body fat percentage. DISCUSSION: Our findings suggest that a disadvantageous body composition is programmed in early life. This may in part underlie the association between maternal obesity and later cardio-metabolic health of the offspring. These findings support the importance of prevention of overweight in women of child-bearing age.
