OBJECTIVE: The objective of this study is to investigate the effects of the UK Pregnancies Better Eating and Activity Trial (UPBEAT) behavioral intervention on dietary patterns in obese pregnant women.

METHODS: Dietary patterns were derived from Food Frequency Questionnaires using principal component analysis in 183 UPBEAT pilot study participants.

RESULTS: Two unhealthy dietary patterns, processed and traditional, predominantly characterized by foods high in sugar and fat, improved [processed -0.54 (-0.92 to -0.16), P = 0.006 and traditional -0.83 (-1.20 to -0.45), P < 0.001] following the intervention, while a cultural pattern that was found to be associated with the Black African/Caribbean participants did not change [-0.10 (-0.46 to 0.26), P = 0.589].

CONCLUSION: Unhealthy dietary patterns are evident in obese pregnant women. The UPBEAT intervention was effective in improving maternal dietary patterns; however, obese pregnant women from minority ethnic groups may be less receptive to intervention.
