| Popis: | Objective To estimate food intake changes from pre-conception to gestational period according to the degree of food processing. Methods Prospective cohort conducted in a public health care center in Rio de Janeiro with Brazilian pregnant women (n = 189). A food frequency questionnaire was applied at the first (5 th –13 th ) and third (30 th –36 th ) gestational trimesters. The food items were classified according to characteristics of food processing in four groups: unprocessed/minimally processed foods; sugar/fat; processed foods and ultra-processed foods. The variation of food intake according to the degree of processing between the pre-conception and gestational period was compared using paired Student’s t -test. Linear regression models were performed to estimate the association of mother’s characteristics on the variation of food group contribution to the total energy intake between periods. Results Total energy intake was 2415 (SD = 813) in the pre-conception and 2379 (750) kcal in the gestational period. We excluded women who had implausible total energy intake ( 6000 kcal/day). The contribution of unprocessed/minimally processed food group to total energy intake during pregnancy when compared to the pre-conception period was higher [50.5 (14.1) vs . 48.8 (12.4), p-value = 0.048], while the caloric share of ultra-processed food group was lower [41.3 (14.6) vs . 43.1 (12.5), p -value = 0.032]. We observed a negative association of age ( p -value = 0.009) and a positive association of pre-pregnancy BMI ( p -value = 0.060) with the variation of ultra-processed food intake. Conclusions Ultra-processed food intake decreased, while minimally/unprocessed food intake slightly increased from the pre-conception to gestational period. These results indicate potential for a larger improvement in the women’s diet quality and that nutritional counseling interventions in pregnant women are still needed. |
