Objective: To examine the beliefs of women of above average weight about appropriate levels of weight gain in pregnancy.
Design: An in-depth qualitative study of 37 women.
Setting: Women recruited from a city hospital, a rural hospital and by community midwives in the south of England.
Participants: Women were identified via hospital notes or by community midwives. Over a one-year period all women identified who attained the weight of 90 kg by the 30th week of pregnancy were eligible to participate. The sample comprised 37 women. The sample was varied in terms of age, social class, household composition and number of children.
Measurement: Two in-depth interviews were carried out with each interviewee: during late pregnancy and six weeks following childbirth.
Findings: Interviewees were concerned not to weigh more after pregnancy than before. Their perceived ability to control weight gain during pregnancy was varied. In the perceived absence of specific advice from health professionals, they constructed their own views about appropriate levels of weight gain. These were informed by their desire to minimise weight gain and to provide adequate nourishment for the growth and development of their baby. Comments and advice from health professionals were interpreted within the women's own understandings of appropriate levels of weight gain.
Key conclusions and implications for practice: (1) the desire to return to their pre-pregnancy weight was a strong motivating factor among pregnant women of above average weight, but some women lacked confidence in their ability to control weight gain; (2) the health and well-being of their unborn baby is often a central concern in women's decisions about appropriate weight gain; (3) health professionals need to explore the beliefs of women of above average weight about appropriate weight gain in pregnancy; and (4) written information about weight gain may assist women of above average weight in understanding what might be an appropriate level of weight gain during pregnancy.
