Associations between advertisement-supported media exposure and dietary quality among preschool-age children.

Foods of low nutritional quality are heavily marketed to children, and exposure to food ads shapes children's preferences and intake towards advertised foods. Whether food ad exposure independently relates to an overall lower diet quality among children remains unclear. We examined the association between ad-supported media use, a proxy for food ad exposure, and diet quality using the baseline data (2014-2015) from 535 3-5-year-olds in a community-based cohort study. Parents reported their child's dietary intake over 3 days via a diary, and diet quality was assessed with the Healthy Eating Index (HEI-2015) where higher scores reflect greater adherence to USDA dietary guidelines. Children's media exposure was measured through online parent surveys. Mean HEI score was 54.5 (SD = 9.4). In models adjusted for sociodemographic characteristics and metrics of parent diet quality, children's HEI scores were 0.5 points lower (adjusted beta = -0.5 [95% CI: 0.8, -0.1]; P < 0.01) for each 1-h increment in weekly viewing of ad-supported children's TV networks. Children's use of media that may have food ads (e.g., apps, online games) also related to a lower diet quality yet to a lesser extent (adjusted beta -0.2 [-0.2, -0.1]; P < 0.01). In contrast, children's ad-free media use was not associated with diet quality (P = 0.21). Findings support the premise that exposure to food advertisements via media may result in a lower quality diet among children independently of other risk factors.

Influence of child-targeted fast food TV advertising exposure on fast food intake: A longitudinal study of preschool-age children.

INTRODUCTION: Fast food (FF) advertising is a potential risk factor for FF consumption among children, yet the impact of such advertising on children's FF intake has not been assessed in a longitudinal, naturalistic study. Whether parents' FF consumption mitigates advertising effects is also unknown. METHODS: One-year, longitudinal study among 624 preschool-age children, 3-5 years old, and one parent each recruited from New Hampshire, 2014-2015. Parents completed six online surveys every eight weeks and, at each, reported the number of times their children consumed FF in the past week. Each child's advertisement exposure was determined by counting the brand-specific FF advertisements aired within the programs they viewed on children's TV networks during the study. At baseline, parents reported the frequency of their own FF consumption. Data were analyzed in 2017-2018. RESULTS: Three FF brands targeted TV advertising to children during the study: McDonald's, Wendy's and Subway. Few children were exposed to child-targeted advertising for Wendy's or Subway. Results from adjusted Poisson regression models focused on McDonald's showed a differential effect of advertisement exposure on children's McDonald's intake in the past week (any or mean intake) by parental FF consumption (P < 0.01). Specifically, McDonald's intake was consistently high among children whose parents consumed FF more frequently (≥monthly), regardless of children's advertisement exposure. However, advertisement exposure increased the risk of McDonald's intake among children nearly two-fold when parents consumed FF less frequently (

Child-targeted fast-food television advertising exposure is linked with fast-food intake among pre-school children.

OBJECTIVE: To determine whether exposure to child-targeted fast-food (FF) television (TV) advertising is associated with children's FF intake in a non-experimental setting. DESIGN: Cross-sectional survey conducted April-December 2013. Parents reported their pre-school child's TV viewing time, channels watched and past-week FF consumption. Responses were combined with a list of FF commercials (ads) aired on children's TV channels during the same period to calculate children's exposure to child-targeted TV ads for the following chain FF restaurants: McDonald's, Subway and Wendy's (MSW). SETTING: Paediatric and Women, Infants, and Children (WIC) clinics in New Hampshire, USA. SUBJECTS: Parents (n 548) with a child of pre-school age. RESULTS: Children's mean age was 4·4 years; 43·2 % ate MSW in the past week. Among the 40·8 % exposed to MSW ads, 23·3 % had low, 34·2 % moderate and 42·5 % high exposure. McDonald's accounted for over 70 % of children's MSW ad exposure and consumption. Children's MSW consumption was significantly associated with their ad exposure, but not overall TV viewing time. After adjusting for demographics, socio-economic status and other screen time, moderate MSW ad exposure was associated with a 31 % (95 % CI 1·12, 1·53) increase and high MSW ad exposure with a 26 % (95 % CI 1·13, 1·41) increase in the likelihood of consuming MSW in the past week. Further adjustment for parent FF consumption did not change the findings substantially. CONCLUSIONS: Exposure to child-targeted FF TV advertising is positively associated with FF consumption among children of pre-school age, highlighting the vulnerability of young children to persuasive advertising and supporting recommendations to limit child-directed FF marketing.

Child-targeted TV advertising and preschoolers' consumption of high-sugar breakfast cereals.

Breakfast cereals represent the most highly advertised packaged food on child-targeted television, and most ads are for cereals high in sugar. This study examined whether children's TV exposure to child-targeted, high-sugar breakfast cereal (SBC) ads was associated with their consumption of those SBC brands. Parents of 3- to 5-year-old children were recruited from pediatric and Women, Infants, and Children (WIC) clinics in Southern New Hampshire, USA, and completed a cross-sectional survey between April-December 2013. Parents reported their child's consumption of SBC brands; whether their child had watched any of 11 kids' channels in the past week; their child's TV viewing time; and socio-demographics. Children's exposure to child-targeted SBC TV ads was calculated by combining TV channel and viewing time with advertising data for SBC ads aired on kids' TV channels during the same timeframe. Five hundred forty-eight parents completed surveys; 52.7% had an annual household income of $50,000 or less. Children's mean age was 4.4 years, 51.6% were female, and 72.5% were non-Hispanic white. In the past week, 56.9% (N = 312) of children ate SBCs advertised on kids' channels. Overall, 40.6% of children were exposed to child-targeted SBC TV ads in the past week. In fully adjusted analyses, the number of SBC brands children consumed was positively associated with their exposure to child-targeted SBC ads. Children consumed 14% (RR = 1.14, 95% CI: 1.02, 1.27) more SBC brands for every 10 SBC ads seen in the past 7 days. Exposure to child-targeted SBC TV advertising is positively associated with SBC brand consumption among preschool-aged children. These findings support recommendations to limit the marketing of high-sugar foods to young children.

A multicenter study of diet quality on birth weight and gestational age in infants of HIV-infected women.

We determined factors associated with diet quality and assessed the relationship between diet quality, birth weight, and gestational age in a prospective national multicenter cohort study. We evaluated diet quality with the Healthy Eating Index (HEI, scale 0-100) in the third trimester of pregnancy with three 24-hr multiple-pass dietary recalls in 266 HIV+ women enrolled in the Pediatric HIV/AIDS Cohort Study. Covariates included demographics, food security, pre-pregnancy body mass index, HIV disease severity, substance use, and antiretroviral exposures. A two-stage multivariate process using classification and regression trees (CART) followed by multiple regression described HEI tendencies, controlled possible confounding effects, and examined the association of HEI with birth weight and gestational age. To assess the stability of the CART solution, both the HEI 2005 and 2010 were evaluated. The mean HEI scores were 56.1 and 47.5 for the 2005 and 2010 HEI, respectively. The first-stage CART analysis examined the relationship between HEI and covariates. Non-US born versus US-born mothers had higher HEI scores (15-point difference, R2  = 0.28). There was a secondary partition due to alcohol/cigarette/illicit drug usage (3.5-point difference, R2  = 0.03) among US-born women. For the second-stage CART adjusted multiple regression, birth weight z-score was positively related to HEI 2005 and 2010 (partial r's > 0.13, P's ≤ 0.0398), but not gestational age (r = 0.00). We conclude that diet quality among HIV+ women is associated with higher birth weight. Despite the influence of a large cultural effect and poor prenatal behaviors, interventions to improve diet in HIV+ women may help to increase birth weight.

A toy story: Association between young children's knowledge of fast food toy premiums and their fast food consumption.

Fast food restaurants spend millions of dollars annually on child-targeted marketing, a substantial portion of which is allocated to toy premiums for kids' meals. The objectives of this study were to describe fast food toy premiums, and examine whether young children's knowledge of fast food toy premiums was associated with their fast food consumption. Parents of 3- to 5-year old children were recruited from pediatric and WIC clinics in Southern New Hampshire, and completed a cross-sectional survey between April 2013-March 2014. Parents reported whether their children usually knew what toys were being offered at fast food restaurants, and whether children had eaten at any of four restaurants that offer toy premiums with kids' meals (McDonald's, Burger King, Subway, Wendy's) during the 7 days preceding the survey. Seventy-one percent of eligible parents participated (N = 583); 48.4% did not receive any education beyond high school, and 27.1% of children were non-white. Half (49.7%) the children had eaten at one or more of the four fast food restaurants in the past week; one-third (33.9%) had eaten at McDonald's. The four restaurants released 49 unique toy premiums during the survey period; McDonald's released half of these. Even after controlling for parent fast food consumption and sociodemographics, children were 1.38 (95% CI = 1.04, 1.82) times more likely to have consumed McDonald's if they usually knew what toys were offered by fast food restaurants. We did not detect a relationship between children's toy knowledge and their intake of fast food from the other restaurants. In this community-based sample, young children's knowledge of fast food toys was associated with a greater frequency of eating at McDonald's, providing evidence in support of regulating child-directed marketing of unhealthy foods using toys.

School food reduces household income disparities in adolescents' frequency of fruit and vegetable intake.

OBJECTIVE: The aim of this study is to examine whether school food attenuates household income-related disparities in adolescents' frequency of fruit and vegetable intake (FVI). METHOD: Telephone surveys were conducted between 2007 and 2008 with adolescent-parent dyads from Northern New England; participants were randomly assigned to be surveyed at different times throughout the year. The main analysis comprised 1542 adolescents who typically obtained breakfast/lunch at school at least once/week. FVI was measured using 7-day recall of the number of times adolescents consumed fruits and vegetables. Fully adjusted linear regression was used to compare FVI among adolescents who were surveyed while school was in session (currently exposed to school food) to those who were surveyed when school was not in session (currently unexposed to school food). RESULTS: Mean FVI was 8.0 (SD=5.9) times/week. Among adolescents unexposed to school food, household income and FVI were strongly, positively associated. In contrast, among adolescents exposed to school food, FVI was similar across all income categories. We found a significant cross-over interaction between school food and household income in which consuming food at school was associated with higher FVI among adolescents from low-income households versus lower FVI among adolescents from high-income households. CONCLUSION: School food may mitigate income disparities in adolescent FVI. The findings suggest that the school food environment positively influences FVI among low-income adolescents.

Vitamin D3 supplementation and upper respiratory tract infections in a randomized, controlled trial.

BACKGROUND: Randomized controlled trials testing the association between vitamin D status and upper respiratory tract infection (URTI) have given mixed results. During a multicenter, randomized controlled trial of colorectal adenoma chemoprevention, we tested whether 1000 IU/day vitamin D(3) supplementation reduced winter episodes and duration of URTI and its composite syndromes, influenza-like illness (ILI; fever and ≥2 of sore throat, cough, muscle ache, or headache) and colds (no fever, and ≥2 of runny nose, nasal congestion, sneezing, sore throat, cough, swollen or tender neck glands). METHODS: The 2259 trial participants were aged 45-75, in good health, had a history of colorectal adenoma, and had a serum 25-hydroxyvitamin D level ≥12 ng/mL. They were randomized to vitamin D(3) (1000 IU/day), calcium (1200 mg/day), both, or placebo. Of these, 759 participants completed daily symptom diaries. Secondary data included semiannual surveys of all participants. RESULTS: Among those who completed symptom diaries, supplementation did not significantly reduce winter episodes of URTI (rate ratio [RR], 0.93; 95% confidence interval [CI], .79-1.09) including colds (RR, 0.93; 95% CI, .78-1.10) or ILI (RR, 0.95; 95% CI, .62-1.46), nor did it reduce winter days of illness (RR, 1.13; 95% CI, .90-1.43). There was no significant benefit according to adherence, influenza vaccination, body mass index, or baseline vitamin D status. Semiannual surveys of all participants (N = 2228) identified no benefit of supplementation on ILI (odds ratio [OR], 1.14; 95% CI, .84-1.54) or colds (OR, 1.03; 95% CI, .87-1.23). CONCLUSIONS: Supplementation with 1000 IU/day vitamin D(3) did not significantly reduce the incidence or duration of URTI in adults with a baseline serum 25-hydroxyvitamin D level ≥12 ng/mL.

Development of a nutrient-dense food supplement for HIV-infected women in rural Kenya using qualitative and quantitative research methods.

OBJECTIVE: Formative research to facilitate the development, packaging and delivery of a culturally acceptable nutrition intervention for HIV-infected women in rural Kenya for an intervention trial. DESIGN: Focus group discussion on three areas: (i) ingredients and form of the nutrition intervention, (ii) packaging and delivery and (iii) monitoring of adherence. Two single-blind taste tests with eleven different porridge formulations of various combinations of maize flour, soyabeans, peanuts, sorghum, mung beans, dried fish, raisins and dried whole milk. Follow-up acceptability focus group discussion was also conducted. SETTING: Voi, Kenya, community based. SUBJECTS: Focus group discussion and two taste tests (twenty-one women aged 16-55 years). Follow-up acceptability focus group discussion (four women enrolled in intervention trial). RESULTS: The preferred porridge for taste consisted of maize, soyabeans and peanuts. For animal protein, dried whole milk and dried fish were used. Although the women disliked the taste of dried fish, it was acceptable if added in small undetectable quantities. Sugar over lime was favoured for taste. Women believed they could consume at least two cups of porridge per day without displacing their usual meals. The optimal delivery interval was believed to be every two weeks in individual serving packages. Women who had been consuming porridge for several weeks felt the taste was acceptable for long-term consumption. CONCLUSIONS: This formative research resulted in the development, packaging and delivery of a nutrient-dense food supplement using local ingredients to meet the dietary needs of the population and acceptable for daily consumption by women in Kenya for evaluation in an intervention trial.

Maternal anemia and preterm birth among women living with HIV in the United States.

BACKGROUND: Women living with HIV (WLHIV) have a higher prevalence of anemia than women without HIV, possibly related to the effects of HIV and antiretroviral medications. OBJECTIVES: To estimate the prevalence of anemia in the third trimester of pregnancy and the effect of anemia on preterm births in WLHIV in the longitudinal, US-based Pediatric HIV/AIDS Cohort Study (PHACS). METHODS: During the third trimester, we obtained up to three 24-hour dietary recalls to estimate daily intakes of nutrients and measured serum concentrations of iron, vitamin B6, vitamin B12, zinc, folate, ferritin, total iron-binding capacity (TIBC), and high sensitivity C-reactive protein. Third trimester anemia was defined as hemoglobin < 11 g/d and iron-deficiency anemia (IDA) was defined as low ferritin, high TIBC, and low transferrin saturation. A preterm birth was defined as birth at < 37 completed weeks of gestation, regardless of etiology. We fit separate modified Poisson regression models for each outcome (anemia, preterm birth) and each main exposure, adjusted for confounders, and report adjusted prevalence ratios (aPR) and 95% CIs. RESULTS: Of the 267 WLHIV, 50% were anemic in the third trimester, of whom 43.5% (n = 57/131) had IDA. On average, women with anemia were younger, were more likely to be black, started antiretroviral medications in the second trimester, had a low CD4 count (<200 cells/mm3) early in pregnancy, and were less likely to meet recommended intakes for iron, B6, and folate. The prevalence of anemia was greater in WLHIV with a low CD4 count (aPR = 1.65; 95% CI: 1.20-2.27) and high HIV viral load (>10,000 copies/mL; aPR = 1.38; 95% CI: 1.02-1.87). In total, 16% of women delivered preterm. Anemia was associated with a 2-fold (aPR = 2.04; 95% CI: 1.12-3.71) higher prevalence of preterm births. CONCLUSIONS: Anemia is common in pregnant WLHIV, highlighting the need to address the underlying factors and clinical outcomes of anemia in this population.

Nutrition issues in the HIV-infected injection drug user: findings from the nutrition for healthy living cohort.

OBJECTIVE: The purpose of this paper is to highlight disparities between injection drug users (IDUs) and those who had never been IDUs from the Nutrition for Healthy Living (NFHL) cohort. Although IDUs were enrolled in the cohort throughout its duration, few analyses have sought to highlight findings specific to them. METHODS: NFHL, a prospective, longitudinal cohort conducted from 1995-2005, included 881 human immunodeficiency virus (HIV) -infected men and women over the age of 18. Subjects were seen every 6 months; body composition and dietary and laboratory data were collected. Individuals were classified as current IDUs, past IDUs, and never-IDUs. The classification of ever-IDU combined current and past users. RESULTS: In NFHL, a higher proportion of ever-IDUs were women, African American, had a high school education or less, smoked, and were housing insecure and food insecure compared to never-IDUs. Ever-IDUs had lower total, soluble, and insoluble fiber and individual micronutrient intakes. A higher proportion of ever-IDUs had hepatitis C and HIV-related symptoms, used highly active antiretroviral therapy (HAART) less, and had a CD4 count <500 cells/mm3, than never-IDUs, at the study endpoint. CONCLUSIONS: The course of HIV infection in past and current IDUs appears to be unique and requires more investigation. Physiologic and sociodemographic characteristics of IDUs contribute to poor disease management and nutritional status. Classic manifestations of HIV persist in IDUs in the HAART era.

Fast food intake and excess weight gain over a 1-year period among preschool-age children.

BACKGROUND: Fast food is cross-sectionally associated with having overweight and obesity in young children. OBJECTIVES: To examine whether fast food intake independently contributes to the development of overweight and obesity among preschool-age children. METHODS: Prospective cohort of 3- to 5-year-old children (n = 541) followed for 1 year. Children's height and weight were objectively measured at baseline and study end. Parents reported their child's fast food intake frequency in the past week from 11 chain fast food restaurants in six online follow-up surveys, completed approximately 8 weeks apart. Poisson regression with robust standard errors modelled the risk of a child increasing in weight status (ie, transitioning from a having a healthy weight to having overweight or from having overweight to having obesity) over the study period in relation to their average weekly fast food intake, adjusted for sociodemographics, child obesogenic behaviours, and parent weight status. RESULTS: At baseline, 18.1% of children had overweight and 9.8% had obesity; 8.1% of children transitioned to a greater weight status over the 1-year period. Mean fast food intake frequency among consumers was 2.1 (SD: 1.4) times per week. The risk of increasing in weight status increased linearly with each additional time fast food was consumed in an average week over the study year (RR: 1.38; 95% CI, 1.13-1.67; P < .01). CONCLUSIONS: Greater fast food intake over 1 year was associated with increasing weight status during that time in this preschool-age cohort.

Third Trimester Vitamin D Status Is Associated With Birth Outcomes and Linear Growth of HIV-Exposed Uninfected Infants in the United States.

BACKGROUND: Vitamin D status in pregnancy may influence the risk of prematurity, birth size, and child postnatal growth, but few studies have examined the relationship among pregnant women living with HIV. METHODS: We conducted a prospective cohort study of 257 HIV-infected mothers and their HIV-exposed uninfected infants who were enrolled in the 2009-2011 nutrition substudy of the Surveillance Monitoring for ART Toxicities (SMARTT) study. HIV-infected pregnant women had serum 25-hydroxyvitamin D (25(OH)D) assessed in the third trimester of pregnancy, and their infants' growth and neurodevelopment were evaluated at birth and approximately 1 year of age. RESULTS: The mean third trimester serum 25(OH)D concentration was 35.4 ± 14.2 ng/mL with 15% of women classified as vitamin D deficient (<20 ng/mL) and 21% as insufficient (20-30 ng/mL). In multivariable models, third trimester vitamin D deficiency and insufficiency were associated with -273 g [95% confidence interval (CI): -450 to -97] and -203 g (95% CI: -370 to -35) lower birth weights compared with vitamin D sufficient women, respectively. Maternal vitamin D deficiency was also associated with shorter gestation (mean difference -0.65 weeks; 95% CI: -1.22 to -0.08) and lower infant length-for-age z-scores at 1 year of age (mean difference: -0.65; 95% CI: -1.18 to -0.13). We found no association of vitamin D status with infant neurodevelopment at 1 year of age. CONCLUSION: Third trimester maternal vitamin D deficiency was associated with lower birth weight, shorter length of gestation, and reduced infant linear growth. Studies and trials of vitamin D supplementation in pregnancy for women living with HIV are warranted.

Exposure to Child-Directed TV Advertising and Preschoolers' Intake of Advertised Cereals.

INTRODUCTION: Child-directed TV advertising is believed to influence children's diets, yet prospective studies in naturalistic settings are absent. This study examined if child-directed TV advertisement exposure for ten brands of high-sugar breakfast cereals was associated with children's intake of those brands prospectively. METHODS: Observational study of 624 preschool-age children and their parents conducted in New Hampshire, 2014-2015. Over 1 year, parents completed a baseline and six online follow-up surveys, one every 8 weeks. Children's exposure to high-sugar breakfast cereal TV advertisements was based on the network-specific TV programs children watched in the 7 days prior to each follow-up assessment, and parents reported children's intake of each advertised high-sugar breakfast cereal brand during that same 7-day period. Data were analyzed in 2017-2018. RESULTS: In the fully adjusted Poisson regression model accounting for repeated measures and brand-specific effects, children with high-sugar breakfast cereal advertisement exposure in the past 7 days (i.e., recent exposure; RR=1.34, 95% CI=1.04, 1.72), at any assessment in the past (RR=1.23, 95% CI=1.06, 1.42), or recent and past exposure (RR=1.37, 95% CI=1.15, 1.63) combined had an increased risk of brand-specific high-sugar breakfast cereal intake. Absolute risk difference of children's high-sugar breakfast cereal intake because of high-sugar breakfast cereal TV advertisement exposure varied by brand. CONCLUSIONS: This naturalistic study demonstrates that child-directed high-sugar breakfast cereal TV advertising was prospectively associated with brand-specific high-sugar breakfast cereal intake among preschoolers. Findings indicate that child-directed advertising influences begin earlier and last longer than previously demonstrated, highlighting limitations of current industry guidelines regarding the marketing of high-sugar foods to children under age 6 years.

Sialic acid levels in breast milk from HIV-positive Tanzanian women and impact of maternal diet.

OBJECTIVE: To quantify total sialic acid in milk from HIV-positive Tanzanian mothers and to determine the impact of maternal diet on milk sialic acid levels. DESIGN: Milk samples were analyzed from 74 HIV-positive, Tanzanian women enrolled in a randomized, controlled clinical study of a dietary macronutrient supplement. Women were provided with a daily protein-calorie supplement and a micronutrient supplement or micronutrient supplement only during the last trimester of pregnancy and up to the first 6 months of breastfeeding. METHODS: Milk samples were collected at approximately 2 weeks and at least 3 months postpartum and assayed for total sialic acid. Milk sialic acid was assessed relative to maternal macronutrient intake, age, BMI, CD4+ cell count and infant birth weight. RESULTS: The mean concentration of milk sialic acid was highest in the first 2 weeks postpartum (6.89 ±â€Š2.79 mmol/l) and declined rapidly by 3 months (2.49 ±â€Š0.60 mmol/l). Sialic acid content in milk was similar between both treatment arms of the study, and did not correlate with maternal macronutrient intake. No correlation was found between maternal age, BMI, CD4+ cell count or infant birth weight and total milk sialic acid concentration. CONCLUSION: Milk sialic acid levels in HIV-positive, Tanzanian women without malnutrition are comparable with reported values for women of European descent and show a similar temporal decline during early lactation. These findings suggest that total milk sialic acid is maintained despite macronutrient deficiencies in maternal diet and support a conserved role for milk sialic acid in neonatal development.

Pre- and post-natal macronutrient supplementation for HIV-positive women in Tanzania: Effects on infant birth weight and HIV transmission.

OBJECTIVE: To determine if a protein-calorie supplement (PCS) plus a micronutrient supplement (MNS) improves outcomes for HIV-infected lactating women and their infants. DESIGN: Randomized, controlled trial. SETTING: Dar es Salaam, Tanzania. SUBJECTS, PARTICIPANTS: Pregnant HIV-infected women enrolled in PMTCT programs who intended to breastfeed for 6 months. INTERVENTION: Randomization 1:1 to administration of a PCS plus MNS versus MNS alone among 96 eligible women beginning in the third trimester and continuing for 6 months of breast-feeding. MAIN OUTCOME MEASURE(S): Primary: infant weight at 3 months. Secondary: maternal BMI at 6 months. RESULTS: PCS resulted in significant increases in daily energy intake compared to MNS at all time points (range of differences: +388-719 Kcal); and increases in daily protein intake (range of differences: +22-33 gm). Infant birth weight (excluding twins) was higher in the PCS than MNS groups: 3.30 kg vs 3.04 kg (p = 0.04). Infant weight at 3 months did not differ between PCS and MNS groups: 5.63 kg vs 5.99 kg (p = 0.07). Maternal BMI at 6 months did not differ between PCS and MNS groups: 24.3 vs 23.8 kg/m2 (p = 0.68). HIV transmission occurred in 0 infants in the PCS group vs 4 in the MNS group (p = 0.03). CONCLUSIONS: In comparison to MNS the PCS + MNS intervention was well tolerated, increased maternal energy and protein intake, and increased infant birth weight, but not weight at 3 months or maternal BMI at 6 months. Reduced infant HIV transmission in the PCS + MNS group was observed. TRIAL REGISTRATION: Clinical Trials.Gov NCT01461863.

Nonvitamin, nonmineral dietary supplementation in HIV-positive people.

BACKGROUND: Many consumers with chronic diseases attempt to take control of their health by using dietary supplements. The objective of this study was to describe current nonvitamin, nonmineral (NVNM) supplement use of HIV-infected persons in the Nutrition for Healthy Living (NFHL) cohort, the financial burden that buying these supplements might pose to this population, and to review current literature on potential interactions between NVNM supplements. METHODS: At baseline visit, participants were educated by a registered dietitian on keeping a complete 3-day food record (including all supplements) for 2 weekdays and 1 weekend day. Seventy-two subjects reported consumption of NVNM supplements, and their food records were reviewed in detail. RESULTS: Each of the 72 subjects in this study used a mean of 6 NVNM supplements, which may have been in the form of a pill, powder, bar, or liquid. The 6 most common were glutamine (51%), N-acetyl-cysteine (36%), fish oil (33%), alpha-lipoic acid (32%), acetyl-l-carnitine (28%), and coenzyme Q10 (28%). Participants were also taking an average of 4 vitamin/mineral supplements; the 6 most common were multivitamin/multimineral (83%), vitamin E (51%), vitamin C (47%), vitamin B complex (43%), calcium (29%), and selenium (28%). CONCLUSIONS: With a total of 107 different types of NVNM supplements, our estimated cost examples indicated a weekly supplement regimen cost of between $25 and $40 dollars. According to literature review, taking an NVNM supplement may involve some risk because many components have not been studied and these products are not tightly regulated.

Dietary supplement use and nutrient intake in HIV-infected persons.

Dietary supplement use was assessed in 368 HIV-infected patients enrolled in the Nutrition for Healthy Living cohort. The objective was to describe the dietary, demographic, and health characteristics of the HIV-infected persons who use different types of dietary supplements. Each patient was categorized in 1 of 4 dietary supplement groups. Extremes in intake of micronutrients were common. Men and women who consumed no supplements reported inadequate intakes of a number of micronutrients. Men using nonvitamin/nonmineral (NVNM) supplements had diets higher in fiber, protein, and 13 of 14 vitamins and minerals. Almost 90% of male NVNM supplement users ingested 1 or more vitamins or minerals in amounts above the tolerable upper limit. Male NVNM supplement users were more likely to be white, well educated, and receiving highly active antiretroviral therapy and more likely to have higher annual incomes, higher CD4 counts, and lower HIV RNA levels. HIV-infected women who were using NVNM supplements exhibited similar trends. Micronutrient inadequacy and excess are relatively common in persons living with HIV infection. Practitioners need to judiciously address optimal nutrient intake from both diet and dietary supplements in this population.

Maternal and child characteristics associated with infant and toddler feeding practices.

OBJECTIVE: To describe maternal/child characteristics associated with important practices of feeding US infants and toddlers aged 4 to 24 months. DESIGN: Cross-sectional analysis of data collected in the 2002 Feeding Infants and Toddlers Study. Maternal/child characteristics associated with compliance to American Academy of Pediatrics feeding guidelines, and maternal/child characteristics associated with specific feeding patterns were assessed. SUBJECTS: A national random sample of mothers (n=2,515) whose infants and toddlers aged 4 to 24 months made up the Feeding Infants and Toddlers Study cohort. STATISTICAL ANALYSIS: Student t tests were used to compare the means and standard errors and were considered significant if P<.05. To predict if the mother/child met a particular recommendation, logistic regression was used to calculate odds ratios (ORs) and 95% confidence intervals. RESULTS: Having a college education was the maternal characteristic associated with the largest number of positive child feeding behaviors. Mothers with a college education were significantly more likely than mothers without a college education to initiate breastfeeding and breastfeed the child to age 6 and 12 months (OR 2.8, 3.2, and 3.9, respectively). College-educated mothers were significantly more likely to comply with the American Academy of Pediatrics juice and complementary feeding recommendations (OR 1.4 and 2.0). In addition, infants and toddlers whose mother had a college education were more likely to consume fruit and less likely to consume sweetened beverages and desserts or candy. Ever breastfeeding the sample child, living in the western region of the United States, and being married and older were also associated with multiple positive practices. The child being in day care was associated with decreased duration of breastfeeding at age 6 and 12 months as well as with consumption of salty snacks. CONCLUSIONS: Initiatives to improve infant and toddler feeding practices should focus on assisting mothers who have less than a college education, who are unmarried, whose child is in day care, or who are enrolled in the Special Supplemental Nutrition Program for Women, Infants, and Children.

Feeding Infants and Toddlers Study: meal and snack intakes of Hispanic and non-Hispanic infants and toddlers.

OBJECTIVE: To describe meal and snack patterns of Hispanic and non-Hispanic infants and toddlers. DESIGN: A cross-sectional telephone survey in which mothers or other primary caregivers reported their infants' and toddlers' food and beverage intake for a 24-hour period. SUBJECTS/SETTING: Subjects were a subset of the national random sample of children aged 4-24 months who participated in the 2002 Feeding Infants and Toddlers Study. The Feeding Infants and Toddlers Study includes a stratified random sample of 3,022 infants and toddlers aged 4-24 months. Three hundred seventy-one Hispanic and 2,637 non-Hispanic children who had 24-hour dietary recalls are included in the subset. ANALYSES: Means+/-standard errors of daily intakes of energy, nutrients, and nutrient densities were calculated, as were percentages of children consuming foods at each eating occasion. RESULTS: Hispanic and non-Hispanic infants and toddlers, on average, were fed seven times per day. Overall, the percentages of children who ate snacks increased with age, and more than 80% of toddlers aged 12-24 months consumed afternoon snacks, with more than 90% of Hispanic children consuming an afternoon snack. In each age group, there were significant differences between ethnic groups in nutrient intakes by eating occasion. No significant difference was seen for energy across all meal occasions. At age 6-11 months, Hispanic children had a significantly lower intake of carbohydrate at dinner and lower intake of saturated fat at afternoon snacks compared with non-Hispanic children (P<.05). The main difference between Hispanic children's and non-Hispanic children's intakes by eating occasion is at age 12-24 months. Hispanics aged 12-24 months had significantly (P<.05) lower percentages of energy from fat and saturated fat and a significantly (P<.05) higher percentage of carbohydrate at lunch compared with non-Hispanic children. For dinner, Hispanic toddlers had significantly (P<.05) lower intakes of total fat and saturated fat compared with non-Hispanic toddlers at age 12-24 months. Overall fiber intake contributed 2 g/meal for both ethnic groups. Snacks contributed, on average, less than 1 g fiber, except Hispanic toddlers had significantly higher fiber intake at afternoon snacks (1.5 g) than non-Hispanic toddlers. Foods frequently consumed at meals and snacks were lacking in whole grains, vegetables, and fruits. Most nutrients were not significantly different between Hispanics and non-Hispanics for meals and snacks. CONCLUSIONS: Considering the sizeable contribution that snacks make toward overall energy, parents and caregivers should plan toddlers' snacks to complement meals by including additional fruits, vegetables, and whole grains that are culturally appropriate rather than fruit drinks, cookies, and crackers. This will increase fiber intake and limit fat and sugar intakes. To develop healthful eating patterns, introduce toddlers to foods eight to 10 times to increase food acceptance and the likelihood of establishing healthful eating patterns. Dietetics professionals need to consider cultural differences when developing meal and snack patterns for Hispanic and non-Hispanic infants and toddlers.
