Partnering & parenting: Effects on changes on physical activity and changes in BMI
In previous analyses of data from the 1973-78 cohort, we have shown that over 10 years, women with a partner and one baby gained almost 4kg more, and those with a partner but no baby gained 1.8kg more, than women without a partner or children. We have also shown that changes in living arrangements were associated with differences in energy intake between survey3 and survey 5. At survey 3 women living with children at both surveys had the highest energy intake, while women who became partnered between those two surveys had the lowest initial intake. Women starting a family between the surveys increased their energy intake, while the other groups decreased theirs. These energy intake results are only partially consistent with the gains in BMI. Therefore we now propose to use similar methodology to analyse the other major component of energy balance by examining changes in levels of physical activity associated with becoming partnered and having babies.
