Perceptions of women and health-care providers in Tokyo of appropriate weight gain during pregnancy.

A mother's underweight status and insufficient weight gain during pregnancy are risk factors for infant low birthweight. Concerns have been raised regarding whether pregnant women are provided with accurate information about weight gain. This study explored how and from whom pregnant women in Tokyo receive information related to body weight. Four focus groups were conducted with nine pregnant women, nine nurse-midwives, and eight obstetricians between March and June 2006. The recorded interviews were content-analyzed. Weight gain was a common concern among the participants, regardless of the women's body size, and sufficient weight gain was rarely mentioned. However, the health-care providers were aware of their lack of expertise and training in behavior modification. Pregnant women consistently expressed a desire for reassurance and praise from health-care providers, which might be a culture-specific phenomenon. The findings point to a need for culturally appropriate and accurate communication about weight gain during pregnancy.
