Lifestyle factors, hormonal contraception, and premenstrual symptoms: the United Kingdom Southampton Women's Survey.

Objective: To estimate the prevalence of premenstrual symptoms in women from the general population in Southampton, U.K., and examine their association with lifestyle factors and contraceptive use.

Do women change their health behaviours in pregnancy? Findings from the Southampton Women's Survey.

A woman's life style choices before and during pregnancy have important implications for her unborn child, but information on behaviour can be unreliable when data are collected retrospectively. In particular there are no large longitudinal datasets that include information collected prospectively before pregnancy to allow accurate description of changes in behaviour into pregnancy. The Southampton Women's Survey is a longitudinal study of women in Southampton, UK, characterised when they were not pregnant and again during pregnancy.

Women's compliance with nutrition and lifestyle recommendations before pregnancy: general population cohort study.

Objective: To examine the extent to which women planning a pregnancy comply with recommendations for nutrition and lifestyle.

Design: Prospective cohort study.

Setting: Southampton, United Kingdom.

What do babies eat? Evaluation of a food frequency questionnaire to assess the diets of infants aged 12 months.

Objective: To evaluate the relative validity of an FFQ for assessing nutrient intakes in 12-month-old infants.

Design And Setting: The FFQ was developed to assess the diets of infants born to women in the Southampton Women's Survey (SWS), a population-based survey of young women and their offspring. The energy and nutrient intakes obtained from an interviewer-administered FFQ were compared with those obtained from 4 d weighed diaries (WD).

Dietary patterns in infancy: the importance of maternal and family influences on feeding practice.

It is not known what constitutes an optimal diet in infancy. There are relatively few studies of weaning practice in the UK, and there is a need for prospective data on the effects of infant diet and nutrition on health in later life. We describe the dietary patterns, defined using principal components analysis of FFQ data, of 1434 infants aged 6 and 12 months, born between 1999 and 2003.
