A downturn or a window of opportunity? How Danish and French parents perceive changes in healthy eating in the transition to parenthood

Alarming childhood obesity rates call for research into the factors that influence a child's environment. Although parents have a large influence on children's eating behaviours, surprisingly little research has explored parental healthy eating patterns. We conducted face-to-face interviews with parents of young children (up to 4 years old) living in Denmark (n = 16) and in France (n = 14) to provide insights into how the transition to parenthood affects the perceived healthfulness of eating behaviours. A problem-centred, Life-Course approach was employed, exploring the topics of interest from the perspective of the participants, and then interpreting these on the background of Social Cognitive Theory. From a cross-cultural sample of mostly well-educated parents living in couples, we found that the transition to parenthood represents a turning point for eating behaviour. Marked differences in dietary changes were perceived across four stages: 1) pregnancy, 2) first months with the baby, 3) complementary feeding and 4) child shares family meals. The findings point to an opposite cross-country perception of the impact of parenthood on food behaviours, and to the idea of what we called an "equalizing effect" on individuals' diet, where having a child triggered "unhealthy" eaters to consider dietary improvements while it imposed challenges to "healthy" eaters to maintain their satisfactory food habits. Contrasting differences on perceived behaviour change mainly appeared in terms of food ethics concern, meat consumption, cooking enjoyment, dietary diversity and sugar consumption. The proposition that low food-health-oriented individuals become healthier and (some) more environmentally conscious, reveals an opportunity for effective strategies and public health messages targeting health and food-ethics behaviour. Nevertheless, findings point to a need to consider individualized health support, addressing parental self-care, physiological changes, stress and negative emotions of early parenthood.

[Effectiveness of mobile technology and weight gain in pregnant women in Callao, Peru]

OBJECTIVE

To evaluate the effectiveness of mobile technology in the appropriate weight gain of pregnant women.

MATERIALS AND METHODS

A quasi-experimental study. The sample included 117 pregnant women attending health facilities at la Dirección Regional de Salud (Diresa), Callao. Messages were sent to 58 pregnant women who formed the experimental group to improve their lifestyles and assistance to prenatal care (APC), while 59 pregnant women received routine education provided for pregnants. Messages were sent every three days. The nutritional status of the pregnant women was evaluated using the pre gestational BMI at the first visit of the APC. The weight gain was obtained from the difference between pre-gestational weight and weight recorded during the last controls.

RESULTS

The adequate weight gain was 27.6% of intervened pregnancies and 25.4% in the non-intervened. The 79.3% pregnant had six or more NPC in the group intervened and 54.2% in the non-intervened. The weight gain was excessive in 5.1% in the non-intervened pregnant and 1.7% in the intervened. The highest percentage of pregnant women with adequate weight gain (32.0%) was observed in the intervened pregnancies with pre-gestacional overwhegith.

CONCLUSIONS

There was no statistic difference in the use of mobile technology for a proper weight gain between both study groups. There were greater fulfillment of APC in intervened pregnancies compared to the non-intervened (p<0.05).

Factors associated with adherence to nutritional recommendations before and during pregnancy

Several epidemiologic studies and clinical trials have demonstrated the value of balanced nutrition during pregnancy. This study aimed to examine the degree of adherence to nutritional recommendations among 1,175 pregnant Spanish women and the factors associated with such adherence to pre-pregnancy and during the first half of pregnancy. Data were collected during June 2004-March 2007 and included socio-demographic and lifestyle factors. Crude and adjusted odds ratios (ORs) and 95% confidence intervals (CIs) were computed using logistic regression models to identify factors associated with adherence to dietary recommendations. Before pregnancy, slightly less than one quarter of the pregnant women (21 percent) did not meet the recommended intake of both vegetables and cereals, and 50 percent did not meet the recommended intake of fruits. Yet most of the participants exceeded the recommended values for proteins. During pregnancy, the adherence for all food types decreased. Factors associated with adherence to the nutritional recommendations were similar before and during pregnancy. Adherence to the Spanish Society of Community Nutrition dietary recommendations was lower among pregnant women who were younger, from a low social class, smokers, and had a low level of physical activity. These findings suggest that nutritional education should become an essential part of antenatal care.

Greek pregnant women demonstrate inadequate micronutrient intake despite supplement use

BACKGROUND/AIM

Maternal diet is important in the outcome of pregnancy and the health of the children. The present cross-sectional study aimed to assess the use of dietary supplements during pregnancy and define the maternal characteristics associated with supplement use.

METHODS

The diet of 100 childbearing women was recorded for three consecutive days and micronutrient supplementation was added to the dietary intake and the median values were used in the analyses.

RESULTS

The majority of the participants (92%) consumed at least one supplement. Supplementation of folic acid (FA) was significantly lower during the third trimester compared to the second (p ≤ .007). Higher intake of Ca and Fe supplements was observed in the second trimester (p ≤ .001). The use of supplements contributed to an attenuated consumption of all reported micronutrients (Mg, Ca, FA, and Fe, p ≤ .001). The principal components analysis revealed that the most important factor contributing to supplementation was primiparity.

CONCLUSIONS

Overall, a high prevalence of micronutrient supplementation during pregnancy was observed without ensuring adequacy in the micronutrient intake. The increased rates of supplement users might be the result of an act for balancing diet in unplanned pregnancies.

Factors associated with a low adherence to a Mediterranean diet pattern in healthy Spanish women before pregnancy

OBJECTIVE

To analyse the factors associated with the level of adherence to a Mediterranean dietary pattern in healthy Spanish women before pregnancy.

DESIGN

A prospective series of 1175 women. An FFQ validated in Spanish populations served to collect dietary data. The Mediterranean Diet Adherence Index was used to assess the level of adherence to a Mediterranean diet pattern. Polytomic regression was performed to identify the associated factors.

SETTING

Catchment area of Virgen de las Nieves University Hospital, Andalusia, Spain.

SUBJECTS

The women were invited to participate in the study at the 20th-22nd gestational week. The selection criteria were: Spanish nationality, 18 years of age or older, singleton pregnancy and absence of health problems that required modifying the diet or physical activity.

RESULTS

An inverse relationship was found between women's age and level of adherence to a Mediterranean diet pattern, with a clear dose-response association: a younger age entailed worse adherence (P < 0·001). The habit of smoking and sedentary lifestyle had a positive relationship with low adherence, giving OR = 5·36 (95 % 1·91, 15·07) for women who smoked >20 cigarettes/d and OR = 2·07 (95 % CI 1·34, 3·17) for sedentary women. Higher age, higher educational level, and higher social class of the women were associated with a higher level of adherence to the Mediterranean diet (P < 0·001).

CONCLUSIONS

In our sample population, younger age, lower social class, primary educational level and elements of an unhealthy lifestyle such as smoking and lack of exercise were associated with low adherence to a Mediterranean diet.

Vitamin D intake and dietary sources in a representative sample of Spanish adults

BACKGROUND

Vitamin D plays an essential role in bone mineralisation and its deficiency is associated with several chronic diseases. Some studies have reported a deficient status of vitamin D in Spanish and European population. The present study aimed to assess vitamin D intake, dietary sources of this nutrient and its adequacy with respect to the dietary reference intakes (DRI) in a representative sample of Spanish adults.

METHODS

Four hundred and eighteen adults (aged 18-60 years) from 15 Spanish provinces were studied. They constituted a representative sample of the Spanish adult population. Energy and nutrient intake were determined using a 24-h dietary recall questionnaire for two consecutive days. Vitamin D intake was compared with the DRI for this vitamin.

RESULTS

Mean (SD) vitamin D intake was 3.5 (4.0) μg day(-1) (69.5% of the DRI). Of the participants studied, 81.6% had vitamin D intakes below the DRI and 68.7% had intakes below 67% of the DRI. Of the vitamin D, 91.4% came from food sources and 8.6% came from dietary supplements. The main food sources of vitamin D were fish, eggs, dairy products, cereals, oils and meat. In addition, those subjects who met the DRI for vitamin D had a higher consumption of fish, vegetables and fruits and a lower consumption of meats than those subjects who did not meet the DRI.

CONCLUSIONS

Vitamin D intake was inadequate in the sample of the adult Spanish population. Therefore, an increase in the consumption of oily fish, as well as fortified dairy products and cereals, might help to improve vitamin D intake.

Dietary intake in pregnant women in a Spanish Mediterranean area: as good as it is supposed to be?

OBJECTIVE

To assess food and nutrient intakes and compliance with nutritional recommendations in pregnant women according to selected sociodemographic characteristics.

DESIGN

Cross-sectional study based on data from the INMA-Valencia cohort (Spain), which recruited pregnant women between 2004 and 2005. Information on maternal sociodemographics and anthropometry was collected. Dietary intake was assessed through an FFQ. Intakes of foods were compared with Spanish food-based dietary guidelines. Intake inadequacy for nutrients was assessed using the Dietary Reference Intakes of the US Institute of Medicine.

SETTING

Valencia, Spain.

SUBJECTS

We studied 822 pregnant women who had information on dietary intake during their first trimester of pregnancy.

RESULTS

More than 50% of pregnant women did not meet the guidelines for cereals and legumes; reported intakes of carbohydrates, n-3 and n-6 fatty acids were below recommendations and exceeded the total fat intake according to dietary references. Dietary inadequacy for folate, Fe and vitamin E ranged from 99% to 68%. Vegetable intake was related to age only. Younger and less educated women showed lower intakes of protein and n-3 fatty acids and higher intakes of trans-fatty acids as well as greater inadequacy for micronutrients. Spanish women reported lower intakes of fruit and carbohydrates and higher intakes of protein, total fat, SFA, MUFA and n-3 fatty acids compared with their foreign-born counterparts.

CONCLUSIONS

Women in the studied area have inadequate intakes of several nutrients relevant during pregnancy. Age, education and country of origin are factors significantly related to dietary intake and adequacy.

Healthy Eating Index during pregnancy according to pre-gravid and gravid weight status

Objective

To assess differences in the Healthy Eating Index (HEI) during pregnancy with the pre-gravid and gravid weight status of women.

Design

Cross-sectional.

Setting

Athens, Greece.

Subjects

One hundred pregnant women, inhabitants of Athens.

Results

The mean raw HEI score of the sample was 66·9 (sd 7·6) and the mean HEI adjusted for energy intake was 66·9 (sd 0·6). No difference was recorded between the adjusted HEI and different gravidities, the embryo’s sex, different income categories or education. When HEI was categorised as low, average and adequate, living in an urban residence increased the odds for demonstrating low HEI score (OR = 10·231, 95 % CI 1·300, 80·487). HEI score during pregnancy was significantly higher in participants who were either pre-gravidly underweight or of normal body weight (BW). In relation to the gestational weight status, the highest HEI scores and protein intake were shown in the underweight and of normal BW participants compared with the obese. According to the simple correspondence analysis, adequate HEI was associated with rural residence and being underweight or having normal BW during pregnancy. Low HEI was associated with overweight and obesity during pregnancy, with obesity before pregnancy and living in an urban environment. HEI was negatively correlated to the pre-conceptional and gestational BMI (r = −0·298, P ≤ 0·003 and r = −0·345, P ≤ 0·001) and to the week of gestation (r = −0·285, P ≤ 0·004).

Conclusions

Overall, the HEI of the sample was mediocre. Women who were underweight or of normal BW exhibited a better diet quality compared with obese women; thus the latter consist a population in greater need for supervised nutrition and dietary counselling during pregnancy.

[Folic acid intake from diet and supplements in a population of pregnant women in Valencia, Spain]

BACKGROUND AND OBJECTIVES

We examined the dietary intake and the use of supplements of folic acid (FA) in a cohort of pregnant women. We also explored the factors associated with non-compliance of both the recommended intake (RI) of 600 μg/day and the supplement use of 400 μg/day provided to prevent neural tube defects (NTD).

PATIENTS AND METHODS

We studied 782 pregnant women from the INMA-Valencia cohort. The dietary intake was estimated using a food frequency questionnaire in two periods of pregnancy; from preconception to the second month and from the 3rd to the 7th month. Information on supplement use was also collected which allowed us to estimate the total FA intake (diet+supplements). We explored factors associated with non-compliance of the recommendations by logistic regression.

RESULTS

The periconceptional mean daily FA intake was 304 μg/day. FA supplements were taken by 19.2, 30.2 and 66.2% of women in preconception, first and second month of pregnancy, respectively. Among women using supplements in periconception, 30% exceeded the tolerable upper intake level (UL) of 1.000 μg/day. Non-compliance with RI was more common among women of foreign origin, of low educational level, who smoked, with unplanned pregnancy, who did not visit a private gynaecologist, who had had children or without previous medical illness.

CONCLUSIONS

Diet by itself is not sufficient to reach RI for FA during pregnancy and many women initiate supplement use after the recommended period and inadequately. The youngest women, with lowest educational attainment and unplanned pregnancies are more likely not to comply.
