Relationships between excessive gestational weight gain and energy and macronutrient intake in pregnant women

Diet intake and adherence to recommendations in women with gestational diabetes mellitus

BACKGROUND/OBJECTIVES

Gestational diabetes mellitus (GDM) is best managed via lifestyle changes. We aimed at investigating to which extent women with GDM adhered to dietary recommendations and to which extent an impact was observed on the glycaemic control compared to women without GDM.

SUBJECTS/METHODS

Women with overweight/obesity (n = 349) were recruited in early pregnancy. GDM was diagnosed with a 2-h oral glucose tolerance test in mid-or-early pregnancy (median 25.9 and 14.7 gestational weeks). Dietary assessments included an index of dietary quality (good ≥ 10 and poor < 10/15 scores) and 3-day food-diaries with nutrient intake calculated and dietary patterns identified. Glucose and insulin concentrations were analysed from blood samples collected in late pregnancy (after GDM diagnosis).

RESULTS

Women with GDM (n = 98) followed more often a healthier dietary pattern (62.2%) than women without GDM (49.0%, p < 0.05), but no difference in good dietary quality was seen (53% vs. 59.8%, p = 0.071). While the majority of women with GDM adhered to some recommendations, 51% to carbohydrate, 54.1% to total fat and 69.4% to sucrose, only 16.3% adhered to the protein and 4.1% to the fibre intake recommendations. Women with GDM had lower adherence to protein, total fat and fibre recommendations but higher adherence to that of sucrose than women without GDM (p < 0.05). A good dietary quality was associated with lower insulin and HOMA2-IR values (p < 0.05).

CONCLUSIONS

Adherence to dietary recommendations, particularly fibre and protein intake, is unsatisfactory in women with GDM. Overall dietary quality is related to better control of glucose metabolism proposing a target for dietary counselling.

Dietary and Nutrient Intake, Eating Habits, and ItsAssociation with Maternal Gestational Weight Gain and Offspring’s Birth Weight in Pregnant Adolescents

Pregnant adolescents’ diet and eating habits are inadequate; however, their association with gestational weight gain (GWG) is uncertain. We aimed to analyze whether there is an association between dietary and nutrient intake and eating habits with GWG among pregnant adolescents and their offspring’s birth weight. A longitudinal study was performed with 530 participants. We assessed GWG and applied several tools, such as a food frequency questionnaire and 24-h recall, to obtain dietary and nutrient intake and eating habits. The birth weight of adolescents’ offspring was registered. Later, we performed crude and adjusted Poisson models. The mean age was 15.8 ± 1.3 years. Of all food groups, the lowest frequency of adequate intake corresponded to vegetables (7%) and legumes (10.2%). Excessive (36.8%) and insufficient (40.9%) GWG were observed. Pregnant adolescents with inadequate legumes intake increased the probability of excessive GWG: (PR 1.86 95% CI 1.00–3.44). Cereals and grains were positively associated with GWG: (PR 1.65, 95% CI 1.18–2.29). Energy, macronutrient intake, and eating habits were not associated with GWG. Offspring’s small gestational age (SGA) increased when pregnant adolescents had inadequate sugar-sweetened beverages intake: PR (1.58, 95% CI 1.01–2.49) and when pregnant adolescent watched television (TV). In our sample of Mexican adolescents, dietary and nutrient intake and eating habits were inadequate. Excessive dietary intake from cereals, grains, and animal-sourced foods along with insufficient legumes were associated with excessive GWG. Watching TV while adolescents ate was associated with the birth weight of the offspring.

Longitudinal Nutritional Intakes in Italian Pregnant Women in Comparison with National Nutritional Guidelines

BACKGROUND

Nutritional quality during pregnancy is crucial for mother and child health and their short/long-term outcomes. The aim of this study is to evaluate the adherence to nutritional recommendations in Italy during the three pregnancy trimesters in Normal Weight (NW) and Over Weight (OW) women.

METHODS

Data from a multicenter randomized controlled trial included 176 women (NW = 133; OW = 43) with healthy singleton pregnancies enrolled within 13 + 6 weeks of gestation. Dietary intake was assessed every trimester by a Food Frequency Questionnaire.

RESULTS

OW and NW had similar gestational weight gain. However, as Institute of Medicine (IOM) recommend lower gestational weight gain (GWG) for OW, they exceeded the suggested range. In both groups, caloric intake during the three trimesters never met recommendations. Protein intake in first and second trimester was higher than recommendations, as was sugars percentage. Dietary fiber intake was lower in OW. Polyunsaturated fatty acids, calcium, iron and folic acid requirements were never satisfied, while sodium intake exceeded recommendations.

CONCLUSIONS

NW and OW women in Italy do not adhere to nutritional recommendations during pregnancy, with lower caloric intake, protein and sugars excess and inadequacies in micronutrients intake. Pregnant women in Italy should be provided with an adequate counseling and educational intervention as well as supplementation when indicated.

Energy Intake and Food Restriction as Determinant Factors of Chronic Energy Deficiency among Pregnant Women in Rural Area of Sungai Sembilan, Riau, Indonesia

BACKGROUND OF THE STUDY: Maternal malnutrition is a major public health problem in Indonesia which is shown by high prevalence of chronic energy deficiency (CED) among pregnant women. CED was expressed by the measurement of Mid Upper Arm Circumference (MUAC) showing value less than 23.5 cm. AIM OF THE STUDY: This study aimed to identify the factors associated with chronic energy deficiency among pregnant women in rural area, Riau Province. METHODOLOGY: A community- based cross sectional study was conducted among 130 samples of pregnant women in Sungai Sembilan Community Health Center in June 2020. Data was collected using structured and field-study questionnaires. Mid Upper Arm Circumference (MUAC) was measured by MUAC tape. Energy and protein intake were assessed using 24-hour food recall. Multiple logistic regression was employed to analyse factors associated with CED by using SPSS version 20. RESULTS: The prevalence of CED among pregnant women was 64.9%. Age of mothers, food restriction, infection disease status, protein and energy intake were associated significantly with CED. Furthermore, energy intake and food restriction in pregnancy were risk factors of CED (AOR = 3.04, 95% CI: 1.1 – 8.3 and AOR = 6.73, 95% CI: 1.33 – 33.9, respectively). We found that proportion of energy intake below 80% RDA and mothers with food restriction were higher among CED group. CONCLUSION: High prevalence of chronic energy deficiency (CED) was found among pregnant women. Hence, innovative intervention was required to overcome this problem.

The Associations Between Maternal Socioeconomic Factors and Adequacy of Energy and Macronutrient Intakes in Pregnant Women From Yucatan, Mexico

BACKGROUND

Socioeconomic factors influence diet quality during pregnancy. However, dearth of evidence about the influence on energy and macronutrients adequacy calls for research.

OBJECTIVE

To analyze the association between socioeconomic factors and adequacy rates of energy and macronutrients intakes in pregnant women from Merida, Yucatan, Mexico.

METHODS

During September to December 2019, we applied a socioeconomic questionnaire and three 24-hour dietary recalls to 83 pregnant females resident in Merida, Yucatan. Energy and macronutrient intakes were compared with the estimated trimester-specific energy and macronutrient requirements to calculate adequacies (%). Outcome variables were average adequacy of energy, carbohydrates, total fat, and protein intakes and the main predictors were maternal education, monthly family income, working status, and marital status. Descriptive statistics of adequacy were calculated for each category of predictors. The association between socioeconomic factors and outcome variables was analyzed through simple and multiple linear regression models.

RESULTS

Adequacy rates of energy and macronutrients decreased as education and familial income levels increased, as well as among unemployed women. Consistently with these results, simple linear regressions showed that years of education, family income, and working status (i.e., women working to earn money), were negatively associated with adequacy rates of energy and macronutrients intakes. When all predictors and covariates were included in a multiple linear regression model, only having a job was significantly associated with adequacy rates. Marital status was not associated with outcomes.

CONCLUSIONS

Women in disadvantaged socioeconomic conditions (unemployed and low levels of education and familial income) show greater energy and macronutrient intakes.

The Relationship of Diet and Physical Activity with Weight Gain and Weight Gain Prevention in Women of Reproductive Age

Reproductive-age women often see increased weight gain, which carries an increased risk of long-term overweight and obesity and adverse maternal and child health outcomes. Supporting women to achieve optimal weight through lifestyle modification (diet and physical activity) is of critical importance to reduce weight gain across key reproductive life-stages (preconception, pregnancy and postpartum). This review comprehensively summarizes the current state of knowledge on the contribution of diet and physical activity to weight gain and weight gain prevention in reproductive-aged women. Suboptimal diets including a higher proportion of discretionary choices or energy intake from fats, added sugars, sweets or processed foods are associated with higher weight gain, whereas increased consumption of core foods including fruits, vegetables and whole grains and engaging in regular physical activity are associated with reduced weight gain in reproductive age women. Diet and physical activity contributing to excessive gestational weight gain are well documented. However, there is limited research assessing diet and physical activity components associated with weight gain during the preconception and postpartum period. This review highlights the need for further research to identify key dietary and physical activity components targeting the critical windows of reproductive life-stages in women to best guide interventions to prevent weight gain.
