Impact of sociodemographic factors on the consumption of tubers in Brazil

Abstract Background Although tubers play a significant role in Brazilian agriculture, very little is known about the intake of tubers among the Brazilian population. The objective of this study was to characterize the intake of tubers across Brazil. The types of tubers consumed were quantified, and the impact of geographic and sociodemographic factors was assessed. Methods This cross-sectional study is based on dietary intake data of 33,504 subjects obtained from the Brazilian National Dietary Survey. All tuber containing foods were identified, and the contribution of different tubers to overall tuber consumption in Brazil was quantified. Descriptive analyses assessed the impact of macroregion and sociodemographic characteristics on tuber consumption, and differences in intake were assessed using statistical tests. Lastly, the dietary intakes of tuber consumers and non-consumers were compared after adjusting for energy and covariates to determine if there were any major differences in dietary intakes between the two groups. Results Fifty-five percent of the Brazilian population consumed tubers, which differed by macroregion. The intake of tubers among consumers also differed between macroregions. Overall, rural areas reported significantly higher mean daily intakes of tubers (122 g/day) among tuber consumers than urban areas (95 g/day). Mandioca and potato were the most commonly consumed tubers (59 and 43% prevalence, respectively, on any of the 2 days), while the highest daily intakes amongst tuber consumers across Brazil were noted for sweet potato (156 g/day) and potato (95 g/day). On a macroregion level, among tuber consumers, mandioca had the highest prevalence of consumption in the North (94%), Northeast (83%), and Central-West (68%), while consumption of potatoes was most prevalent in the Southeast (63%) and South (62%). Compared to women, small but significantly higher tuber intakes were noted for males (108 vs. 85 g/day). There were no significant differences in intakes among income quintiles. After adjusting for energy and other covariates, nutrient intakes between tuber and non-tuber consumers were not meaningfully different, with the exception of sodium (+ 6.0% comparing non-tuber to tuber consumers), iron (+ 6.1%), zinc (+ 5.7%), vitamin C (+ 8.3%), riboflavin (+ 9.0%), and folate (+ 7.9%). Conclusions Tuber consumption is influenced by regional and sociodemographic characteristics of the Brazilian population. When looking at energy-adjusted nutrient intakes, diets of tuber consumers have resulted in somewhat lower intakes of some micronutrients, namely riboflavin, folate, vitamin C, iron, sodium, and zinc.

AbstractObjectiveTo describe nutrient intakes, characterize dietary patterns and analyse their associations with sociodemographic characteristics among pregnant women in Shaanxi, China.DesignPopulation-based cross-sectional survey.SettingTwenty counties and ten districts in Shaanxi Province of Northwest China, 2013.SubjectsWomen (n 7462) were recruited using a stratified multistage random sampling method to report diets during pregnancy, at 0–12 months (median 3 months; 10th–90th percentile, 0–7 months) after delivery.ResultsPregnant women had higher intakes of fat, niacin and vitamin E than the nutrient reference values, while most micronutrients such as vitamin A, folate, Ca and Zn were reportedly low. Women in the highest education, occupation and household income groups had higher nutrient intakes than those in the lowest groups. Nutrient intake differences also existed by geographic area, residence and maternal age at delivery. Three dietary patterns were identified: balanced pattern, vegetarian pattern and snacks pattern. Participants with high balanced pattern scores tended to be better educated, wealthier, 25–29 years old at delivery, working outside and living in urban areas and central Shaanxi. Women with high scores on the vegetarian pattern and snacks pattern tended to be in low balanced pattern score groups, and had lower nutrient intakes than those in the high balanced pattern score groups.ConclusionsThe study suggested that pregnant women in Shaanxi, China had low intakes of most nutrients such as vitamin A, folate and Ca. Dietary patterns and most nutrient intakes varied by sociodemographic characteristics. Targeted programmes are needed to improve dietary intakes and dietary patterns among sociodemographically disadvantaged groups.

The Impact

Dairy foods are under-consumed among Chinese children. We modeled the impact of increased dairy consumption on nutrient inadequacy and assessed whether the consumption of formulated milk powder for children ≥3 years (FMP3+) is useful for reducing nutrient gaps. Data from 3–8-year-old children, with completed socio-demographic and dietary measurements from the China Health and Nutrition Survey 2015, were used (n = 1122). Dietary intakes were modeled in two scenarios: Scenario 1 added FMP3+ or cow’s milk to reported diet to reach recommended dairy intakes; Scenario 2 replaced the currently consumed milk with an equal volume of FMP3+. Reported nutrient intakes were compared with each model. Only 32.5% of children consumed dairy products; the average intake amount in total was 48.6 g/day. Most children (97.6%) did not meet dairy intake recommendation. Inadequate nutrient intakes were observed for calcium, potassium, thiamin, riboflavin, vitamin C and selenium. In Scenario 1, both FMP3+ and cow’s milk improved the intake of all analyzed nutrients. In Scenario 2, FMP3+ substitution increased the intake of most nutrients, and reduced the proportion of children with an inadequate intake of vitamin C, thiamin, vitamin A, iron, zinc and potassium. Thus, increasing dairy consumption would reduce nutrient gaps, and FMP3+ is a good food source to help children meet nutrient requirements.

Abstract Background Iranian diet quality has been evaluated using indices that are not based on Iranian dietary guidelines. This study examined the applicability of the Healthy Eating Index (HEI) by examining associations with sociodemographics, nutrient intakes and nutrient adequacy. Methods Household sociodemographics and dietary intakes (three 24-h dietary recalls) were collected in the cross-sectional National Comprehensive Study on Household Food Consumption Patterns and Nutritional Status 2001-2003. Household diet quality was calculated using the HEI. Regression analyses examined associations between diet quality and sociodemographics, nutrient intakes and nutrient adequacy. Results A total of 6584 households were included in this study. Age (β-coeff 2.11; 95% CI: 1.64, 2.44), education (β-coeff 4.58; 4.05, 5.11) and living in urban areas (β-coeff 2.87; 2.56, 3.19) (as reported by the household head) were positively associated with diet quality. Higher diet quality was associated with higher intake of protein (% energy) (β-coeff 0.08; 0.07, 0.08), calcium (mg/day) (β-coeff 12.10; 11.23, 12.98), iron (mg/day) (β-coeff 0.04; 0.02, 0.05), vitamin C (mg/day) (β-coeff 3.61; 3.45, 3.77) and fibre (g/day) (β-coeff 0.12; 0.11, 0.14), lower intake of sodium (mg/day) (β-coeff -83.45; -93.02, -73.88) and adequate intake of calcium (mg/day) (OR 1.10; 95% CI: 1.09, 1.12) and vitamin C (mg/day) (1.19; 1.18, 1.20). Conclusions Higher HEI was associated with a range of sociodemographics and better nutrient intakes and nutrient adequacy. Key messages HEI was applicable for assessing the diet quality of Iranian households.

Cu And Zn

Defining optimal dietary intakes of Cu and Zn throughout the life cycle continues to present a considerable challenge for nutrition scientists. Although the daily intake of these micronutrients is below that currently recommended for many groups, traditional biochemical indicators of nutritional status for these trace metals largely remain within the normal range. Thus, it is unclear whether the recommended daily intakes may be unnecessarily high, or if the commonly-used markers simply lack the necessary sensitivity and specificity that are required for accurately assessing Cu and Zn status. The increasing number of reports that daily supplements with these trace metals enhance the activities of selective metalloenzymes and specific cellular and organ processes further points out the need to differentiate between meeting the requirement and providing optimal nutriture. Results from recent studies suggesting that alternative molecular and functional markers possess sufficient sensitivity to better assess Cu and Zn status are discussed. Likewise, recent studies evaluating the impact of very low and excessive levels of dietary Mn and Mo on selective biochemical and metabolic indicators are reviewed.

As nutrient-dense fruits, mangoes are commonly consumed globally and are important sources of nutrients in the diet. Nonetheless, mangoes remain relatively under-consumed in the United States. The objective of the present analysis was to examine nutrient intakes, diet quality, and health outcomes using data from NHANES 2001–2018 in children and adult mango consumers (n = 291; adults n = 449) compared with mango non-consumers (children n = 28,257; adults n = 44,574). Daily energy and nutrient intakes were adjusted for a complex sample design of NHANES using appropriate weights. Mango consumption was not associated with daily energy intake, compared with non-consumption, in both children and adults. Children consuming mangoes had a significantly lower daily intake of added sugar, sodium, total fat, and a higher intake of dietary fiber, magnesium, potassium, total choline, vitamin C, and vitamin D, compared with non-consumers. In adults, mango consumers had significantly higher daily intakes of dietary fiber, magnesium, potassium, folate, vitamin A, vitamin C, and vitamin E and significantly lower intakes of added sugar and cholesterol, compared with non-consumers. Mango consumption was also associated with a better diet quality vs. mango non-consumers (p < 0.0001). Mango consumption in adolescents was associated with lower BMI z-scores, compared with non-consumption. In adults, BMI scores, waist circumference, and body weight were significantly lower only in male mango consumers when compared with mango non-consumers. The current results support that mango consumption is associated with improved nutrient intakes, diet quality, and certain health outcomes. Thus, dietary strategies that aim to increase mango consumption in the American population should be evaluated as part of future dietary guidance.

The Impact

AbstractFortifying complementary foods with lipid-based nutrient supplements (LNS) may improve energy and nutrient intakes of infants at risk for undernutrition. We aimed to determine the relative validity of an interactive 24-h recall (i-24-HR) for assessing the impact of an LNS intervention on dietary intakes of energy and nutrients among rural Malawian 9–10-month-old infants (n 132) participating in the International Lipid‐Based Nutrient Supplements Dose (iLiNS-DOSE) trial. Dietary data were collected for the same day via i-24-HR and weighed food records. Inter-method agreements were estimated overall and by intervention group, using Bland–Altman plots and paired t tests; measurement error models (differential error); and percentage of food omissions and intrusions were estimated. Overall, inter-method differences in mean intakes of energy and most nutrients were not significant. When stratified by group, recalled energy intakes were under-estimated (−368 kJ; P=0·01) in the control but not in the intervention group (−42 kJ; P=0·6). This differential reporting error was related to an over-estimation of recalled LNS (8·1 v. 4·5 g; P<0·001) in the intervention group, compensating for an under-estimation of energy and nutrient intakes from complementary foods. Sources of measurement error in the i-24-HR were under-estimations of starchy staples, meat/fish/eggs and legumes/nuts/seeds (overall percentage agreement between 38 and 89 %; P<0·028); and over-estimations of added sugar, soups/broths and LNS (overall percentage agreement between 138 and 149 %; P<0·001). Common (>30 % eating occasions) omissions were milk/fish/eggs, starchy roots/vegetables and sweetened snacks. Common intrusions were milk/yogurt. Starchy staples and LNS were recalled when consumed (>85 %) (i.e. matched). These results emphasise the importance of considering differential error when interpreting dietary results in LNS trials.

The Impact

AbstractStrong evidence exists linking poor diet to increased risk of overweight, obesity and non-communicable diseases. Reformulation initiatives, whereby the food industry gradually reduces energy, sodium, sugar, fat and saturated fat content of their products, are identified as important strategies to improve dietary intakes. The analysis aimed to examine the impact of voluntary reformulation, changes to products on the market and changes in consumer preferences on dietary intakes in Ireland from 2005 to 2017. Data on composition and volume sales (kg/ year) of products available on the market in 2005 and 2017 were collected from 15 Food Drink Ireland (FDI) member companies via online templates. These products were assigned to appropriate food and beverage groups identified in four Irish University Nutrition Alliance (IUNA) surveys of preschool children (1–4 years), children (5–12 years), teenagers (13–17 years) and adults (18–90 years). Assignment of FDI products to IUNA foods and beverages was carried out using weighted distributions for a given group of foods. The weightings were taken from the sales volumes of similar products relative to one another in a given category in a given year. Monte Carlo simulations were used to run the IUNA survey consumption data with both sets of weighted composition data from 2005 and 2017. The Creme Global intake model was used to estimate daily energy and nutrient intakes for all four populations during 2005 and 2017. The Wilcoxon-signed rank test was used to test for differences between the two years. Changes in both the products available on the market and market share of these products were observed from 2005 to 2017. The nutrient with the greatest intake reduction between the two years for all ages was sugar. Children and teens were the most affected, where total sugar intakes reduced by 3.2g/d and 2.7g/d, respectively. This reduction was primarily driven by the beverage category. There were modest saturated fat intake reductions observed for teens and adults (0.2g/d and 0.5g/d, respectively). Energy, total fat and sodium intakes for all ages remained relatively stable between the two years. This analysis highlights the impact of not only food industry efforts but also consumer choices on nutrient intakes in Ireland. It is worth noting that the data collected predates the sugar tax on sugar-sweetened beverages in Ireland. Reductions in sugar intakes were not compensated by total fat or energy increases.

Purpose. The purpose of this study was to assess rural and urban differences in the dietary intakes, physical activity levels and weight status of a large sample of Canadian youth in both 2005 and 2008.Materials and Methods. A cross-sectional study of rural and urban adolescents (n=10,023) in Alberta was conducted in both 2005 and 2008 using a web-based survey.Results. There was an overall positive change in nutrient intakes between 2005 and 2008; however, rural residents generally had a poorer nutrient profile than urban residents (P<.001). They consumed less fibre and a greater percent energy from saturated fat. The mean physical activity scores increased among rural youth between 2005 and 2008 (P<.001), while remaining unchanged among urban youth. Residence was significantly related to weight status in 2005 (P=.017), but not in 2008.Conclusion. Although there were small improvements in nutrient intakes from 2005 to 2008, several differences in the lifestyle behaviours of adolescents living in rural and urban areas were found. The results of this study emphasize the importance of making policy and program recommendations to support healthy lifestyle behaviours within the context of the environments in which adolescents live.

The Impact

Background: Understanding the impact of local communities on wellbeing is a paramount Sustainable Development Goal. In order to inform people-centred planning interventions, it is important to understand what demographic groups need supportive communities the most and where. This study explored associations between perceived neighbourhood characteristics and cognitive vulnerability, and the moderating role of age and urbanity of the place of residence. Methods: A convenience sample of 224 Irish adults completed a survey assessing cognitive vulnerability and perceptions of neighbourhood qualities, together with sociodemographic and residential information. Correlational analyses explored bivariate associations as well as moderating effects. A subsample (n = 142) provided qualitative accounts of their preferences of neighbourhood characteristics. Results: Regression analyses showed that controlling for sociodemographic factors, higher self-reported neighbourhood pleasantness was associated with lower cognitive vulnerability, particularly in older adults who lived in the most rural and urban areas (p = 0.006). Qualitative accounts suggested urban–rural variations in perceived accessibility and perceptual stressors, and age-related variations in social preferences. Conclusions: Our findings indicate a complex association between neighbourhood characteristics and cognitive wellbeing, highlighting the potential benefits of neighbourhood pleasantness for cognition particularly for older people in very rural or very urbanised places. Implications for research and environmental interventions are discussed.
