This chapter examines the pattern of maternal weight change over two consecutive pregnancies, with particular focus on differences associated with the mother's parity. A canonical correlation coefficient indicates that the pattern of weight change during and after pregnancy tends to repeat consistently between consecutive pregnancies. An observed canonical correlation of 0.598 means that a straight line rather accurately predicts the gain-loss pattern between pregnancies when summarized by a linear function. Treating six measured weights over two pregnancies as a single multivariate response shows that parity (measured as a binary variable, no previous live births versus at least one previous live birth) likely influences the maternal weight change pattern. Three multivariate procedures give formal and identical analytic results.

Keywords: pregnant women; maternal weight gain; parity; pregnancy
