RESUMO

OBJECTIVE: To determine the mediating effect of direct preschool and parent nutrition education on changes in skin carotenoids scores over 2 years in children of Mexican heritage. DESIGN: In a quasi-experimental, community-based study, two school districts were randomly assigned to either a comparison group (parent workshops unrelated to nutrition) or a childhood obesity prevention intervention group which included nutrition education at family nights for parents and at school for children. Changes in skin carotenoid intensity scores (diffCAROT, year 2015 minus 2013) were measured in children as a proxy for fruit and vegetable consumption using Resonance Raman Spectroscopy. SETTING: Two rural, low-income, school districts from a county in California's Central Valley. PARTICIPANTS: 316 Mexican heritage families with children aged 3-8 years. RESULTS: Intervention group children improved over 2 years in skin carotenoid scores relative to comparison group children (diffCAROT mean +1419 (sd 9540) v. -3473 (sd 9272), P = 0·0001). Parent attendance at nutrition education classes partially mediated the intervention effect on diffCAROT (P = 0·02). Controlling for child's age and other covariates, participation in preschool during the study had a significant positive effect on diffCAROT among intervention children compared with controls (P < 0·03), whereas no significant difference by group was observed among those not enrolled in preschool or already enrolled in elementary school. CONCLUSIONS: Programmes that combine direct parent and preschool nutrition education may be effective in low-income Mexican heritage families to improve children's intake of fruit and vegetables.

RESUMO

BACKGROUND: Obesity and overweight have increased dramatically in the United States over the last decades. The complexity of interrelated causal factors that result in obesity needs to be addressed within the cultural dynamic of sub-populations. In this study, we sought to estimate the effects of a multifaceted, community-based intervention on body mass index (BMI) among Mexican-heritage children. METHODS: Niños Sanos, Familia Sana (Healthy Children, Healthy Family) was a quasi-experimental intervention study designed to reduce the rate of BMI growth among Mexican-heritage children in California's Central Valley. Two rural communities were matched based on demographic and environmental characteristics and were assigned as the intervention or comparison community. The three-year intervention included parent workshops on nutrition and physical activity; school-based nutrition lessons and enhanced physical education program for children; and a monthly voucher for fruits and vegetables. Eligible children were between 3 and 8 years old at baseline. Intent-to-treat analyses were estimated using linear mixed-effect models with random intercepts. We ran a series of models for each gender where predictors were fixed except interactions between age groups and obesity status at baseline with intervention to determine the magnitude of impact on BMI. RESULTS: At baseline, mean (SD) BMI z-score (zBMI) was 0.97 (0.98) in the intervention group (n = 387) and 0.98 (1.02) in the comparison group (n = 313) (NS). The intervention was significantly associated with log-transformed BMI (ß = 0.04 (0.02), P = 0.03) and zBMI (ß = 0.25 (0.12), P = 0.04) among boys and log-transformed BMI among obese girls (ß = - 0.04 (0.02), P = 0.04). The intervention was significantly and inversely associated with BMI in obese boys and girls across all age groups and normal weight boys in the oldest group (over 6 years) relative to their counterparts in the comparison community. CONCLUSIONS: A community-based, multifaceted intervention was effective at slowing the rate of BMI growth among Mexican-heritage children. Our findings suggest that practitioners should consider strategies that address gender disparities and work with a variety of stakeholders to target childhood obesity.

RESUMO

The purpose of this study was to examine relative validity of a food frequency questionnaire (FFQ) to measure food acculturation in young Mexican-origin children. In 2006, Spanish-speaking staff interviewed mothers in a community-based sample of households from Ventura, California (US) (n = 95) and Guanajuato, Mexico (MX) (n = 200). Data included two 24-h dietary recalls (24-DR); a 30-item FFQ; and anthropometry of the children. To measure construct, convergent, and discriminant validity, data analyses included factor analysis, Spearman correlations, t-test, respectively. Factor analysis revealed two constructs: 1) a US food pattern including hamburgers, pizza, hot dogs, fried chicken, juice, cereal, pastries, lower fat milk, quesadillas, and American cheese and 2) a MX food pattern including tortillas, fried beans, rice/noodles, whole milk, and pan dulce (sweet bread). Out of 22 food items that could be compared across the FFQ and mean 24-DRs, 17 were significantly, though weakly, correlated (highest r = 0.62, for whole milk). The mean US food pattern score was significantly higher, and the MX food pattern score, lower in US children than in MX children (p < 0.0001). After adjusting for child's age and gender; mother's education; and household size, the US food pattern score was positively related to body mass index (BMI) z-scores (beta coefficient: +0.29, p = - 0.004), whereas the MX food pattern score was negatively related to BMI z-scores (beta coefficient: -0.28, p = 0.002). This tool may be useful to evaluate nutrition education interventions to prevent childhood obesity on both sides of the border.

RESUMO

OBJECTIVE: The present paper examines the influence of age and gender on food patterns of Latino children. DESIGN: Data are from baseline of a 5-year, quasi-experimental obesity prevention study: Niños Sanos, Familia Sana (NSFS; Healthy Children, Healthy Families). In 2012, the researchers interviewed Latino parents, using a thirty-item questionnaire to ask about their children's food consumption and feeding practices. Statistical tests included t tests and ANCOVA. SETTING: Rural communities in California's Central Valley, USA. SUBJECTS: Two hundred and seventeen parents (87-89% born in Mexico) and their children (aged 2-8 years). RESULTS: Fifty-one per cent of the children were overweight or obese (≥85th percentile of BMI for age and gender). Mean BMI Z-scores were not significantly different in boys (1·10 (SD 1·07)) and girls (0·92 (SD 1·04); P=0·12). In bivariate analysis, children aged 2-4 years consumed fast and convenience foods less often (P=0·04) and WIC (Supplemental Nutrition Program for Women, Infants, and Children)-allowable foods more often than children aged 5-8 years (P=0·01). In ANCOVA, neither age nor gender was significantly related to food patterns. Mother's acculturation level was positively related to children's consumption of fast and convenience foods (P=0·0002) and negatively related to consumption of WIC foods (P=0·01). Providing role modelling and structure in scheduling meals and snacks had a positive effect on the vegetable pattern (P=0·0007), whereas meal skipping was associated with more frequent fast and convenience food consumption (P=0·04). CONCLUSIONS: Acculturation and child feeding practices jointly influence food patterns in Latino immigrant children and indicate a need for interventions that maintain diet quality as children transition to school.

RESUMO

BACKGROUND: Overweight and obese children are likely to develop serious health problems. Among children in the U.S., Latino children are affected disproportionally by the obesity epidemic. Niños Sanos, Familia Sana (Healthy Children, Healthy Family) is a five-year, multi-faceted intervention study to decrease the rate of BMI growth in Mexican origin children in California's Central Valley. This paper describes the methodology applied to develop and launch the study. METHODS/DESIGN: Investigators use a community-based participatory research approach to develop a quasi-experimental intervention consisting of four main components including nutrition, physical activity, economic and art-community engagement. Each component's definition, method of delivery, data collection and evaluation are described. Strategies to maintain engagement of the comparison community are reported as well. DISCUSSION: We present a study methodology for an obesity prevention intervention in communities with unique environmental conditions due to rural and isolated location, limited infrastructure capacity and limited resources. This combined with numerous cultural considerations and an unstable population with limited exposure to researcher expectations necessitates reassessment and adaptation of recruitment strategies, intervention delivery and data collection methods. Trial registration # NCT01900613. TRIAL REGISTRATION: NCT01900613.

RESUMO

OBJECTIVE: To assess the relationship of acculturation with physical activity and sedentary behaviours among Hispanic women in California. DESIGN: Data from the 2005 California Women's Health Survey (CWHS) - a cross-sectional telephonic survey of health indicators and health-related behaviours and attitudes - were used. SETTING: Using a random-digit dialling process, data were collected monthly from January to December 2005. SUBJECTS: A total of 1298 women aged ≥18 years in California who self-identified as Hispanic. RESULTS: Of the participants included in the analysis, 49 % were adherent to physical activity recommendations (with 150 min of weekly activity signifying adherence). There was no significant association between language acculturation and moderate or vigorous physical activity after controlling for potential confounders such as smoking, age and employment status. There was also no association between duration of residence in the USA and moderate or vigorous physical activity. Language acculturation was positively associated with television (TV) viewing, with highly acculturated women reporting more hours of TV viewing compared with women with an intermediate acculturation score (P = 0·0001), and those with an intermediate score reporting more hours of TV viewing compared with those with a low score (P = 0·003). This relationship persisted after inclusion of smoking, employment status, age and education in the model. CONCLUSIONS: Higher levels of language acculturation may be associated with increased sedentary behaviours because of the influence of US culture on those women who have assimilated to the culture. Acculturation is an important factor to be taken into account when designing health education interventions for the Hispanic female population.

RESUMO

This paper describes qualitative and quantitative aspects of testing a 34-item Toddler-Feeding Questionnaire (TFQ), designed for use in Latino families, and the associations between feeding practices and toddler dietary outcomes. Qualitative methods included review by an expert panel for content validity and cognitive testing of the tool to assess face validity. Quantitative analyses included use of exploratory factor analysis for construct validity; Pearson's correlations for test-retest reliability; Cronbach's alpha (α) for internal reliability; and multivariate regression for investigating relationships between feeding practices and toddler diet and anthropometry. Interviews were conducted using a convenience sample of 94 Latino mother and toddler dyads obtained largely through the Supplemental Nutrition Program for Women, Infants and Children (WIC). Data collection included household characteristics, self-reported early-infant feeding practices, the toddler's dietary intake, and anthropometric measurements. Factor analysis suggests the TFQ contains three subscales: indulgent; authoritative; and environmental influences. The TFQ demonstrated acceptable reliability for most measures. As hypothesized, indulgent practices in Latino toddlers were associated with increased energy consumption and higher intakes of total fat, saturated fat, and sweetened beverages. This tool may be useful in future research exploring the relationship of toddler feeding practices to nutritional outcomes in Latino families.

RESUMO

Little is known about toddler feeding practices, particularly among Mexican American mothers. A convenience sample of 18 Mexican-American mothers with toddlers participated in individual in-depth interviews. In determining what to feed her child, mothers tended to cater to the child's preferences rather than exposing the child to different foods or repeating attempts to feed previously unaccepted foods. In deciding when to feed food or beverage, more than half said the child's cue was primary. Findings indicate that an indulgent feeding style may dominate compared to other styles in the toddler developmental stage in Mexican-American mothers.

RESUMO

BACKGROUND: Food insecurity, limited access to adequate food, in adulthood is associated with poor health outcomes that suggest a pattern of accelerated aging. However, little is known about factors that impact food insecurity in midlife which in turn could help to identify potential pathways of accelerated aging. METHODS: Low-income adults (n = 17,866; 2014 National Health Interview Survey), ages 18 to 84, completed a 10-item food security module and answered questions regarding health challenges (chronic conditions and functional limitations) and financial worry. We used multinomial logistic regression for complex samples to assess the association of health challenges and financial worry with food insecurity status and determine whether these associations differed by age group, while adjusting for poverty, sex, race/ethnicity, education, family structure, social security, and food assistance. RESULTS: Food insecurity rates were highest in late- (37.5%) and early- (36.0%) midlife, relative to younger (33.7%) and older (20.2%) age groups and, furthermore, age moderated the relationship between food insecurity and both risk factors (interaction p-values < .05, for both). The effects of poor health were stronger in midlife relative to younger and older ages. Unlike younger and older adults, however, adults in midlife showed high levels of food insecurity regardless of financial worry. CONCLUSIONS: Findings suggest that food insecurity in midlife may be more severe than previously thought. Greater efforts are needed to identify those at greatest risk and intervene early to slow premature aging.

RESUMO

OBJECTIVE: To examine factors related to attendance of Mexican-heritage parents at community-based nutrition classes to prevent childhood obesity. METHODS: Starting in 2011, interviewers collected baseline data from Niños Sanos Familia Sana (Healthy Children, Healthy Families) participants in rural California. Educators maintained attendance logs from 2012 to 2014. Informed by the Theory of Planned Behavior, interviewers administered an exit survey in 2015 to collect data on attitudes, subjective norms, health motivations, and perceived control related to attendance. Multivariable ordinal logistic regression analysis examined the correlates of attendance (n = 194, intervention group only). RESULTS: Controlling for mother's age, marital status, acculturation, and employment, attitudes and subjective norms were significantly related to attendance (odds ratio = 1.27; 95% confidence interval [CI], 1.18-1.37; P < .001). CONCLUSIONS AND IMPLICATIONS: In these Mexican-heritage participants, attitudes and subjective norms were significant correlates of attendance. The Theory of Planned Behavior may shed light on attendance of high-risk groups but further testing of instruments is needed.

RESUMO

The usefulness of an evaluation instrument is dependent on its reliability, validity, and ability to capture change. The latter psychometric characteristic is particularly important, yet is often neglected. The purpose of this study was to assess the sensitivity of a psychosocial fruit and vegetable evaluation tool for use by two US Department of Agriculture community-based programs. As part of a prospective randomized controlled trial, a sample of limited-resource women (n=93), recruited from eight counties, provided dietary recalls, behavioral assessments, and psychosocial assessments. A randomly selected subsample was used for venipuncture (n=55). Sensitivity of the tool was estimated using serum carotenoids, selected micronutrients, fruit/vegetable servings, and fruit/vegetable behaviors. Controlling for energy intake at baseline and change in energy intake, the change scores for the tool were correlated with reported changes in fruit and vegetable behaviors (r=0.28, P=0.01), vitamin C (r=0.25, P=0.02), and the biomarker serum carotenoids (r=0.31, P=0.02). This systematic process yielded a moderately sensitive evaluation tool useful with a limited-resource audience participating in two US Department of Agriculture programs. This is the first study to estimate sensitivity of a psychosocial tool for a fruit and vegetable intervention.

RESUMO

OBJECTIVE: The purpose is to describe the development and validation of a tool to measure the degree of past food insecurity in an immigrant US population. DESIGN: Focus group discussions and a structured interview. As a first step, focus group discussions were conducted among immigrant Latino mothers. Based on these discussions, an 8-item tool was developed and pilot-tested in a convenience sample of mothers. SETTING: California. PARTICIPANTS: Twenty-two low-income Latino mothers with children, ages 4 to 5 years, in the focus groups and 85 low-income Latino and white mothers of young children in the structured interviews. ANALYSES: Constant comparative analysis, Cronbach alpha, Spearman correlations, Chi-square, and Kruskal-Wallis test. RESULTS: Internal consistency of the remaining 7 items was good (Cronbach alpha = 0.84). Evidence of convergent validity included significant correlations between past food insecurity and maternal education (r = -0.45, p < .0001), crowding in the mother's childhood household (r = +0.30, p < .006), and past food insufficiency (r = +0.74, p < .0001). Foreign-born Latino mothers reported significantly greater levels of past food insecurity than US-born mothers, demonstrating discriminant validity (p < .01). CONCLUSIONS AND IMPLICATIONS: This tool may be useful to determine how past deprivation influences current food choices and other nutrition-related behaviors in low-income Latino immigrants.

RESUMO

OBJECTIVE: Development of an evaluation tool of psychosocial constructs for use by participants in 2 federal programs, Food Stamp Nutrition Education and the Expanded Food and Nutrition Education Program. DESIGN: Cross-sectional data from a longitudinal study. PARTICIPANTS: Limited-resource women (n = 111) living in low-income communities. MEASURES: Test-retest reliability, internal consistency, ethnic differences, convergent validity. ANALYSIS: Spearman rank order correlation, analysis of variance, principal components analysis. RESULTS: Reliability coefficients ranged from a low of r = .18 (not significant) to r = .74 (P < .0001). Two items were deleted for not meeting criteria for reliability and 2 for redundancy. Ethnic differences at baseline were significant for 1 item. Domain constructs loaded on 4 to 5 factors for the biopsychosocial framework. Estimates of convergent validity of 9 constructs led to the deletion of 3 (ie, perceived barriers, social support, and perceived norms), with retention of perceived benefits, perceived control, self-efficacy, readiness to eat more fruit, readiness to eat more vegetables, and perceived diet quality. As an estimate of convergent validity, the final version of the tool with 6 constructs remaining showed significant correlations with indicators of diet quality: serum carotenoid values (r = .38, P < .001); hypothesized nutrients calculated from the mean of 3 24-hour dietary recalls (vitamin C, r = .47, P < .0001; vitamin A, r = .39, P < .0001; folate, r = .37, P < .0001; beta-carotene, r =.31, P < .001; and fiber, r = .46, P < .0001); fruit and vegetable servings (r = 0.55, P < .0001); Healthy Eating Index (r = .27, P < .05); and a fruit and vegetable behavioral scale (r = .60, P < .0001). CONCLUSION AND IMPLICATIONS: This systematic process yielded a fruit and vegetable evaluation tool useful for practitioners and researchers. This is the first validation study of this type to estimate convergent validity with 5 indicators of diet quality, including a biomarker.

RESUMO

The purpose was to compare maternal perceptions, feeding practices, and overweight status of children in immigrant households in California (US) with a cohort in Guanajuato, Mexico (MX). In 2006, staff interviewed mothers and weighed and measured their children, 1-6 years (US: n = 95 and MX: n = 200). Prevalence of overweight [body mass index z-score (BMIZ) >1.0 and <1.65] and obesity (BMIZ > 1.65) was 21.1 and 28.4% in the US respectively, compared to 11.5 and 12.9% in MX (p < 0.001). No differences were observed in maternal ability to identify correctly the child's weight status or ever being told the child was overweight. US children ate away from home more often (p < 0.0001), had fewer family meals (p < 0.0001), and played outdoors less often than MX children (p < 0.0002). Further analyses should examine how differences in eating and activity patterns explain the disparity in childhood obesity across the countries.

RESUMO

BACKGROUND: The results of studies examining food insecurity and obesity in adults are conflicting. Discrepancies could be due to the use of different instruments or to cultural factors that influence response patterns. OBJECTIVE: The goal was to examine the relation of food insecurity to weight status in low-income Latino women. DESIGN: A cross-sectional survey was conducted among 559 low-income Latino women selected by convenience sampling. The survey included the 18-item US Household Food Security Scale, 2 items related to current and past food insufficiency, demographic information, and measured heights and weights. Data were collected between February and May 2001 in 6 California counties. The main outcomes were frequency of overweight and obesity, defined by a body mass index (in kg/m(2)) of 25-29.9 (overweight) and >30 (obese). Data analysis included analysis of variance, Mantel-Haenszel chi-square test, and logistic regression. RESULTS: The prevalence of food insecurity was 50-60%, and that of obesity was 37.4%. Controlling for years spent in the United States, per capita income, and parity, food insecurity with hunger, measured by the 10-item adult scale of the Food Security Scale, was significantly related to obesity (OR: 1.98; 95% CI: 1.14, 3.53). No interaction between years spent in the United States and current food insecurity was observed. Current food insufficiency, as measured by a single item, was not related to obesity. However, severe past food insufficiency was related to obesity in the US-born population only. CONCLUSION: Food insecurity appears to be related to obesity in Latino women, but choice of instruments might influence the results.

RESUMO

OBJECTIVE: The purpose of this research was to examine the relationship of child-feeding practices and other factors to overweight in low-income Mexican-American preschool-aged children. DESIGN: Cross-sectional survey with anthropometric measurements of mothers and target children. Trained bilingual staff interviewed the parents to collect data on child-feeding strategies, food patterns, child's health history, parental acculturation level, food insecurity, and other household characteristics. Subjects and setting Complete data were available from 204 low-income Mexican-American parents residing in California with at least one child aged 3 to 5 years. Outcomes measured Risk of overweight was defined as body mass index (BMI) (measured as weight [in kilograms]/height [in meters](2)) >/=85th percentile and overweight was defined as BMI >/=95th percentile. The Student t test, chi(2) test, and logistic regression were used. RESULTS: Three variables were positively related to risk of overweight: birth weight (odds ratio [OR], 2.31; 95% confidence interval [CI], 1.11 to 4.82), mother's BMI >/=30 (OR, 2.05; 95% CI, 1.11 to 3.79), and juice intake (OR, 2.33; 95% CI, 1.09 to 4.98). Being enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children was negatively related to risk of overweight (OR, 0.40; 95% CI, 0.21 to 0.75). Additional variables related to overweight were monthly income >$1,500 (OR, 2.33; 95% CI, 1.00 to 5.42) and child takes food from the refrigerator between meals (OR, 0.32; 95% CI, 0.13 to 0.76). CONCLUSIONS: The results of this study suggest that biological and socioeconomic factors are more associated with overweight in Mexican-American preschool-aged children than most of the self-reported child-feeding strategies.

RESUMO

OBJECTIVE: To examine the relationship of food insecurity to nutrition of Mexican-American preschoolers. DESIGN: Cross-sectional survey of low-income Mexican-American families with children of preschool age (3 to 6 years). Data included food security using the Radimer/ Cornell scale; acculturation; parental education; monthly income; past experience of food insecurity; and child weight, height, and frequency of consuming 57 foods. Weight-for-height z scores (WHZ), height- for-age z (HAZ) scores, and the percentage of overweight (> or = 85th percentile WHZ) were calculated. SUBJECTS/SETTING: A convenience sample of Mexican-American families (n=211) was recruited through Head Start, Healthy Start, Migrant Education, and the Special Supplemental Nutrition Program for Women, Infants, and Children in Tulare, Fresno, Monterey, and Kern counties in California. Statistical analyses Analysis of variance, t tests, Spearman's correlations, and Mantel Haenszel chi2. RESULTS: Limited education, lack of English proficiency, and low income were negatively correlated with food security (r = -0.31 to -0.44, P<.0001). After controlling for acculturation, children in severely food-insecure households were less likely to meet Food Guide Pyramid guidelines than other children (median number of food groups > or = recommended levels [interquartile range]: 2.0 (2.0) vs 3.0 (2.0), P<.006). Although WHZ (mean +/- SD = 1.28 +/- 1.80) and percent overweight (48%, N=19) tended to peak among children from household level food insecure families, no significant differences were found in weight or height status of children by level of food insecurity. APPLICATIONS/CONCLUSIONS: Dietetics professionals working with low-income Hispanic-American families should screen for different levels of food insecurity to determine needs for nutrition education and other services.

RESUMO

OBJECTIVE: To report 6 psychometric properties of food behavior checklist (FBC) items and then to use these properties to systematically reduce the number of items on this evaluation tool. DESIGN: Random assignment to the intervention and control groups. SETTING: Low-income communities. PARTICIPANTS: Women (N = 132) from limited-resource families. MAIN OUTCOME MEASURES: Reliability, internal consistency, baseline differences by ethnicity, sensitivity to change, and criterion and convergent validity of subscales. RESULTS: The fruit and vegetable subscale showed a significant correlation with serum carotenoid values (r =.44, P <.001), indicating acceptable criterion validity. Milk, fat/cholesterol, diet quality, food security, and fruit/vegetable subscales showed significant correlations with dietary variables. Nineteen items have acceptable reliability. Twenty items showed no baseline differences by ethnic group. Eleven of the 15 items expected to show change following the intervention demonstrated sensitivity to change. CONCLUSIONS AND IMPLICATIONS: This brief food behavior checklist (16 items) is easy to administer to a client group, has an elementary reading level (fourth grade), and has a low respondent burden in addition to meeting requirements for validity, reliability, and sensitivity to change. This study establishes a process that can be used by other researchers to develop and further refine instruments for use in community health promotion interventions.

RESUMO

OBJECTIVE: To examine the relationship between food insecurity and food supplies in Latino households. DESIGN: Cross-sectional survey, conducted February to May 2001. SETTING: Six California counties. PARTICIPANTS: Convenience sampling was used to recruit 274 low-income Latino families with preschool children from the Special Supplemental Nutrition Program for Women, Infants and Children (WIC), Head Start, and other community-based organizations. Complete data were available for 256 families. VARIABLES MEASURED: Food security, household food scores. ANALYSIS: Pearson correlations, Kruskal-Wallis test, and logistics regression. Significance level at P <.05. RESULTS: Controlling for maternal education, food insecurity over the past 3 months was associated with lower household food supplies: dairy, r = -.18, P <.01; fruit, r = -.36, P <.001; grains, r = -.27, P <.0001; meats, r = -.22, P <.001; snack foods, r = -.23, P <.001; and vegetables, r = -.29, P <.001. CONCLUSIONS AND IMPLICATIONS: In Latino households, greater food insecurity is associated with a lower variety of most foods, particularly fruits and vegetables. Future research in Latino households should explore the effects of seasonal food insecurity and household food shortages on food intake of individual household members, especially young children.

RESUMO

It is the position of the Academy of Nutrition and Dietetics that women of childbearing age should adopt a lifestyle optimizing health and reducing risk of birth defects, suboptimal fetal development, and chronic health problems in both mother and child.Components leading to healthy pregnancy outcome include healthy pre-pregnancy weight, appropriate weight gain and physical activity during pregnancy, consumption of a wide variety of foods, appropriate vitamin and mineral supplementation, avoidance of alcohol and other harmful substances, and safe food handling. Nutrition assessment needs to encompass changes in anthropometric,biochemical, and clinical indicators throughout pregnancy. Pregnant women should gain weight according to the 2009 Institute of Medicine Guidelines. Energy needs are no higher than the Estimated Energy Requirement for nonpregnant women until the second trimester; thereafter, the extra energy need per day is 340 kcal and 452 kcal in the second and third trimesters,respectively. Using the 2010 Dietary Guidelines for Americans, registered dietitian nutritionists and dietetics technicians, registered,can help pregnant women select a food plan based on age, physical activity, trimester, weight gain, and other considerations.Women are encouraged to participate in at least 150 minutes of moderate-intensity aerobic activity spread throughout the week or 30 minutes of moderately intense exercise on most days of the week.When good food choices are made, food consumption to meet extra energy needs and the increased absorption and efficiency of nutrient utilization that occurs in pregnancy are generally adequate to meet most nutrient needs. However, vitamin and mineral supplementation may be important in vulnerable cases including food insecurity; alcohol, tobacco, or other substance dependency; anemia; strict vegetarian (vegan) diet; or poor eating habits. Multiple strategies are needed to support healthy lifestyles for all women, from preconception through the postpartum period. This practice paper supports the Academy of Nutrition and Dietetics' position paper "Nutrition and Lifestyle for a Healthy Pregnancy Outcome" published in the July 2014 Journal of the Academy of Nutrition and Dietetics.
