Longitudinal changes in home food availability and concurrent associations with food and nutrient intake among children at 24-48 months.

OBJECTIVES: To describe changes in home food availability during early childhood, including modified, developmentally sensitive obesogenic scores, and to determine whether home food availability is associated with food and nutrient intakes of children concurrently, over time. DESIGN: Data were drawn from the STRONG Kids 2 longitudinal, birth cohort to achieve the study objectives. Home food availability was assessed with the Home Food Inventory (HFI) and included fifteen food groups (e.g. fruit and vegetables) and three obesogenic scores (one original and two modified). Food and nutrient intakes were measured using the Block FFQ and included twenty-seven food groups and eighteen nutrients (e.g. vitamins A and C, protein). HFI and FFQ were completed by trained researchers or mothers, respectively, at 24, 36 and 48 months. Repeated-measures ANOVA and Spearman's correlations were used to achieve the study objectives. SETTING: Central Illinois, USA. PARTICIPANTS: Participants were 468 children at 24, 36 and 48 months of age. RESULTS: Availability of less nutritious foods and obesogenic foods and beverages increased as children aged, and availability of both nutritious and less nutritious foods were associated with child food and nutrient intake. The three obesogenic scores demonstrated similar, positive associations with the intake of energy, saturated fat, added sugars and kilocalories from sweets. CONCLUSION: These findings offer novel insight into changes in home food availability and associations with food and nutrient intake during early childhood. Additional attention is needed examining antecedents (e.g. built environments, purchasing behaviours) and consequences (e.g. child diet quality and weight) of home food availability.

Infant temperament and mealtime distractions as predictors of preschool Children's bite speed during family mealtime.

Eating behaviors are shaped at an early age, persist into adulthood, and are implicated in the development of physical health outcomes, including obesity. Faster bite speed has been identified as an obesogenic eating behavior, prompting researchers to examine child and family factors associated with children's variability in bite speed. Child temperament, involving phenotypes of reactivity and regulation, and distractions in family food contexts are fruitful areas of investigation, but few studies have examined the interplay among these factors and their associations with bite speed. To address the gap in the literature, we examined relations between early child temperament, family mealtime distractions, and children's observed bite speed. Caregiver report of child temperament at 3 months was measured using the Infant Behavior Questionnaire Very Short Form - Revised. Child mealtime distractions and bite speed were assessed using family mealtime videos that were collected during home visits when children were 18-24 months of age (n = 109). Results revealed that children who were reported to be higher on orienting/regulation at 3 months, and who were more distracted during mealtimes at 18-24 months, had relatively slower bite speeds. No significant interactions were found. The findings from this correlational study inform further investigations into the implications of early temperament and food contexts for the development of eating behaviors implicated in obesity risk.

Avocado Consumption, Abdominal Adiposity, and Oral Glucose Tolerance Among Persons with Overweight and Obesity.

BACKGROUND: Although intake of Hass avocado has been cross-sectionally linked to lower abdominal obesity, knowledge of the effects of avocado consumption on abdominal adiposity and glycemic outcomes remains limited. OBJECTIVE: The effects of avocado consumption on abdominal adiposity, insulin resistance, oral-glucose-tolerance test (OGTT), and estimated ß-cell function were evaluated. METHODS: A total of 105 adults aged 25-45 y (61% female) with BMI ≥25 kg/m2 were randomly assigned to an intervention (N = 53) that received a daily meal with 1 fresh Hass avocado or a control (N = 52) that received an isocaloric meal with similar ingredients without avocado for 12 wk. DXA was used to assess the primary outcomes of abdominal adiposity [visceral adipose tissue (VAT), subcutaneous abdominal adipose tissue (SAAT), and the ratio of VAT to SAAT (VS Ratio)]. Fasted glucose and insulin were used to assess the primary outcomes of insulin resistance (HOMA-IR), and insulin sensitivity (Matsuda index) and ß-cell function (Insulinogenic index) were estimated using an OGTT. Changes between groups were compared using an ANCOVA. Secondary analyses were conducted based on sex. RESULTS: The control group exhibited a greater reduction in SAAT [-54.5 ± 155.8 g (control) compared with 17.4 ± 155.1 g (treatment), P = 0.017] and increase in VS Ratio [0.007 ± 0.047 (control) compared with -0.011 ± 0.044 (treatment), P = 0.024]. Among females, the treatment group exhibited a greater reduction in VAT [1.6 ± 89.8 g (control) compared with -32.9 ± 81.6 g (treatment), P = 0.021] and VS Ratio [0.01 ± 0.05 (control) compared with -0.01 ± 0.03 (treatment), P = 0.001]. Among males, there was no significant difference between groups in changes in abdominal adiposity or glycemic outcomes. CONCLUSIONS: Daily consumption of 1 fresh Hass avocado changed abdominal adiposity distribution among females but did not facilitate improvements in peripheral insulin sensitivity or ß-cell function among adults with overweight and obesity.This study was registered at clinicaltrials.gov as NCT02740439.

Quality of life, coping strategies, and supportive care needs in head and neck cancer survivors: a qualitative study.

PURPOSE: The purpose of this qualitative study was to better understand the lived experience of head and neck cancer (HNC) survivors between 6 months to 9 years post-radiation. Quality of life, coping strategies, concerns for the future, and preferences for supportive care were explored. METHODS: Semi-structured interviews were conducted in 31 HNC survivors from a Midwestern hospital. Interviews were recorded, transcribed verbatim and analyzed using qualitative thematic analysis. RESULTS: Survivors described restrictions on daily living, social eating, and financial concerns. Despite these restrictions, survivors reported an overall high mentality and enjoyment of life. Coping considerations included adapting to a new normal and increased involvement in cancer support and faith groups. Preferences for supportive care included receiving more information about and being more involved in the treatment care plan, referrals to therapy and support groups, and more comprehensive follow-up in survivorship. CONCLUSIONS: While long-term HNC survivors adapt to daily living restrictions, a high proportion continue to have unmet needs. This data can guide the development of HNC survivorship interventions to inform optimal clinical guidelines based on patients' perceived needs. This qualitative study uncovered distinct perceived needs of HNC survivors which can inform future service development. Incorporating referrals to supportive care services including speech language pathologist, physical therapists, and dietitians into the standard of care before, during, and after treatment would assist survivors in adapting to life after treatment and managing long-term health consequences of their disease.

The complexities of family mealtimes in the 21st century: A latent profile analysis.

The goal of the present study was to characterize more than 500 families regarding family mealtime organization patterns. Family profiles were developed based on patterns detected across a set of sociological and psychological variables. Latent profile analyses indicated three distinct subgroups of families: Food Secure and Organized (55% of the sample), Very Low Food Security and Disorganized (27%), and Low Food Security and Organized (18%). Examination of group membership correlates revealed significant differences related to family mealtime behaviors and food preparation strategies, but not food shopping location or areas of requested change around family mealtimes. Findings highlight homogenous subgroups of families on the basis of co-occurring psychological and sociological factors pertinent to family mealtimes, with those families possessing the highest levels of risk in multiple domains also reporting family mealtime organization patterns associated with less healthy eating. Findings provide a snapshot into the organization, and complexities, of family meals for the American family today, highlighting the need for researchers and practitioners interested in promoting healthy food intake within American families to consider both psychological and sociological factors that influence family mealtime organization.

Food parenting topics in social media posts: Development of a coding system, examination of frequency of food parenting concepts, and comparison across Reddit and Facebook.

This study presents development of a coding system to examine food parenting topics presented in posts on social media, and compared topics between two social media platforms (Facebook, Reddit). Publicly available social media posts were gathered from Facebook (2 groups) and Reddit (3 subreddits) and a coding system was developed based on the concept map of food parenting proposed by Vaughn et al. (2016). Based on the developed coding system, we coded posts into overarching food parenting practice constructs (coercive control: attempts to dominate, pressure or impose parents' will on child, structure: organization of child's environment to facilitate competence, autonomy support: supporting child's ability to self-regulate through allowing food choices, conversations about food, and a positive emotional climate) and recipes. We also coded posts dichotomously as including a question or advice-seeking. Differences in frequencies of food parenting constructs presented in posts on Facebook and Reddit were considered using chi-square tests of independence. Of the 2459 posts coded, 900 were related to food parenting (37%). In the subsample of 900, posts related to structure (43%) and recipes (40%) were the most frequent. Close to half of the posts (44%) included questions about food parenting. Frequency of food parenting topics in posts was related to social media platform, with coercive control and structure more frequently discussed on Reddit and recipes more commonly posted on Facebook. Results suggest that food parenting topics discuss on social media differ by platform, which can aid researchers and practitioners in targeting social media-based outreach to the topics of most interest for users. Findings give insight into the everyday food parenting topics and questions that parents and caregivers may be exposed to on social media. TAXONOMY: Development of Feeding; Parenting; Online Information Services.

U.S. Media Enjoyment without Strong Media Literacy Undermines Adolescents' and Mothers' Reported Efforts to Reduce Unhealthy Eating in Jamaica.

We investigate whether media literacy and media use can moderate the association between U.S. media enjoyment and unhealthy eating among remotely acculturating "Americanized" adolescents and their mothers in Jamaica (n = 164 individuals/82 dyads; Madolescent.age  = 12.83, SD = 0.48, 48% female; Mmother_age  = 39.25, SD = 5.71). Socioeconomically diverse participants completed questionnaires reporting their degree of enjoyment of U.S. media (i.e., remote acculturation), media literacy (i.e., critical thinking about food media/advertising), and adherence to national dietary guidelines to reduce sugar/fat. Multilevel modeling showed that enjoying U.S. media and consuming high levels of U.S. TV plus Jamaican TV are associated with lower efforts to reduce sugar and fat. However, high media literacy, whether one's own or a close family member's, weakens or nullifies that association.

Predictors and Outcomes of Mealtime Emotional Climate in Families With Preschoolers.

Objective: Mealtime emotional climate (MEC) is related to parent feeding and mental health, and possibly to child food consumption. However, MEC has been inconsistently assessed with a variety of coding schemes and self-report instruments, and has not been examined longitudinally. This study aims to characterize MEC systematically using an observational, count-based coding scheme; identify whether parent feeding or mental health predict MEC; and examine whether MEC predicts child food consumption and weight. Methods: A subsample of parents (n = 74) recruited from a larger study completed questionnaires when children were about 37 months, participated in a home visit to videotape a mealtime when children were about 41 months, and completed questionnaires again when children were about 51 months old. Maternal and child positive and negative emotions were coded from videotaped mealtimes. Observational data were submitted to cluster analyses, to identify dyads with similar emotion expression patterns, or MEC. Logistic regression was used to identify predictors of MEC, and Analysis of Covariance was used to examine differences between MEC groups. Results: Dyads were characterized as either Positive Expressers (high positive, low negative emotion) or All Expressers (similar positive and negative emotion). Increased food involvement feeding practices were related to decreased likelihood of being an All Expresser. Positive Expressers reported that their children ate more healthy food, compared with All Expressers. Conclusions: Observed MEC is driven by maternal emotion, and may predict child food consumption. Food involvement may promote positive MEC. Improving MEC may increase child consumption of healthy foods.

Family food involvement is related to healthier dietary intake in preschool-aged children.

Children in the United States fall far short of meeting federal dietary recommendations. The unhealthy diets common amongst young children are of crucial public health concern, given that they can inhibit healthy development and are predictive of chronic diseases in adulthood. Research investigating behaviors that are related to dietary habits is crucial to allow a better understanding of the causes of unhealthy dietary practices. Involvement in food preparation is known to be associated with healthy dietary behaviors in school-aged children, but little is known about these behaviors and their correlates in younger children. The present study sought to examine the influences and correlates of involvement in family food preparation in children at ages three and four. Parents of preschool aged children (n = 497) completed surveys including information about demographic background, their children's family food involvement, dietary intake, mealtime routines, and problematic eating behaviors. Data were collected when children were three (wave one of the survey) and four years of age (wave two). Findings from this study indicate that family food involvement at age three is predictive of healthier dietary intake at age four (increased consumption of fruits and vegetables, decreased consumption of fast food). These findings indicate that family food involvement is predictive of healthier dietary behaviors in young children, and that outreach efforts focused on family food involvement in early childhood may improve children's dietary habits.

Longitudinal factor analysis of the Comprehensive Feeding Practices Questionnaire among parents of preschool-aged children.

INTRODUCTION: The Comprehensive Feeding Practices Questionnaire (CFPQ) assesses 12 specific parent feeding practices (Musher-Eizenman & Holub, 2007). However, the original 12-factor structure may not be consistent across age groups, and no studies have yet evaluated the factor structure of the CFPQ over time. Therefore, the aim of the current study is to evaluate the model fit of the original and alternative CFPQ factor structures at two time points in early childhood. METHOD: Mothers (n = 260) of preschoolers completed validated surveys assessing parent feeding practices and child eating behaviors when children were on average 37 months of age at Time 1 (T1), and 57 months of age at Time 2 (T2). Confirmatory Factor Analysis (CFA) and Exploratory Factor Analysis (EFA) procedures were used to evaluate the original CFPQ factor structure, and to identify and evaluate modified factor structures at both time points. RESULTS: The original 12-factor CFPQ model did not adequately fit the data at T1 or T2. EFA identified a 7-factor model at T1, and a 5-factor model at T2. Bivariate correlations provided preliminary evidence for the validity of the modified scales. DISCUSSION: Overall, these findings suggest that parent feeding measures should the developmental significance of specific feeding practices, and/or that parents' reliance on certain feeding practices may shift as children age. Thus, a developmental framework to conceptualize how feeding changes during early childhood is sorely needed.

Children's family experiences: development of the PROMIS® pediatric family relationships measures.

PURPOSE: To describe the development of pediatric family relationships measures, with versions for child self-report (8-17 years) and parent-report for children 5-17 years old. Measures were created for integration into the Patient Reported Outcomes Measurement Information System (PROMIS®). METHODS: Semi-structured interviews with 10 experts, 24 children, and 8 parents were conducted to elicit and clarify essential elements of family relationships. A systematic literature review was conducted to identify item concepts representative of each element. The concepts were transformed into items that were iteratively revised based on cognitive interviews (n = 43 children) and item translatability review. Psychometric studies involving 2846 children and 2262 parents were conducted to further refine and validate the instruments. RESULTS: Qualitative procedures supported the development of content valid Family Relationships item banks. Final child- and parent-report item banks each contain 47 items. Unidimensional item banks were calibrated using IRT-modeling to estimate item parameters representative of the US population and to enable computerized adaptive test administration. Four- and eight-item short forms were constructed for standard fixed format administration. All instruments have strong internal consistency, retest-reliability, and provide precise estimates of various levels of family relationship quality. Preliminary evidence of the instruments' validity was provided by known-group comparisons and convergence with legacy measures. CONCLUSION: The PROMIS pediatric Family Relationships measures can be applied in research focused on determinants, outcomes, and the protective effects of children's subjective family relationship experiences.

Eating, feeding, and feeling: emotional responsiveness mediates longitudinal associations between maternal binge eating, feeding practices, and child weight.

BACKGROUND: Although it is known that maternal disordered eating is related to restrictive feeding practices, there is little research exploring mechanisms for this association or its effects on other feeding practices. The purpose of this study was to assess whether maternal emotion responses mediate the association between maternal binge eating (BE) and child feeding practices, in order to identify potential risk factors for feeding practices that influence child weight. METHODS: This longitudinal observational study included (n = 260) mothers and children from the STRONG Kids Panel Survey. At Wave 1, children were an average of 37 months old (SD = 6.9), and at Wave 2 children were an average of 57 months old (SD = 8.3). Mothers self-reported their frequency of binge eating behavior (Wave 1), responses to children's negative emotions (Wave 1), feeding practices (Wave 1 and Wave 2), and child height and weight were measured at both time points. Using bias-corrected bootstrapping procedures, we tested the hypothesis that longitudinal associations between maternal BE and nonresponsive parent feeding practices would be mediated by parents' unsupportive responses to children's negative emotion. We also tested a serial mediation model positing that maternal BE predicts child body mass index (BMI) percentile change 18-24 months later, indirectly through unsupportive responses to negative emotion and nonresponsive feeding practices. RESULTS: Maternal BE predicted use of more nonresponsive feeding practices (e.g. Emotion Regulation, Restriction for Health, Pressure to Eat, and Food as Reward), indirectly through more Distress responses to children's negative emotions. In the serial mediation model, maternal BE was associated with greater use of Distress responses, which indirectly predicted higher child BMI percentile through Food as Reward feeding practices. CONCLUSIONS: These results suggest that maternal eating and emotion responsiveness are important for understanding the interpersonal context of feeding behaviors, and child weight outcomes. Distress responses may serve as a risk factor for use of unhealthful feeding practices among mothers with BE and these responses may increase children's risk for weight gain. TRIAL REGISTRATION: This study used an observational prospective design. Therefore, it has not been registered as a clinical intervention trial.

The Relationship Between Food Insecurity and BMI for Preschool Children.

OBJECTIVES: The literature exploring the relationship between food insecurity and obesity for preschool-aged children is inconclusive and suffers from inconsistent measurement. This paper explores the relationships between concurrent household and child food insecurity and child overweight as well as differences in these relationships by child gender using a sample of 2-5 year old children. METHODS: Using measured height and weight and responses to the Household Food Security Survey Module collected from a sample of 438 preschool-aged children (mean age 39 months) and their mothers, logistic regression models were fit to estimate the relationship between household and child food insecurity and child BMI. Separate models were fit for girls and boys. RESULTS: Twenty-seven percent of children from food insecure households and 25 % of child food insecure children were overweight or obese (BMI ≥ 85 %). There were no statistically significant associations between either household or child food insecurity and BMI for the full sample. For girls, but not boys, household food insecurity was associated with BMI z-scores (ß = 0.23, p = 0.01). CONCLUSIONS: Although food insecurity and overweight were not significantly associated, a noteworthy proportion of food insecure children were overweight or obese. Programs for young children should address food insecurity and obesity simultaneously by ensuring that young children have regular access to nutrient-dense foods.

Quality of Life in Children With Asthma: A Developmental Perspective.

OBJECTIVE: The current study investigated whether factors associated with quality of life (QOL) in children with asthma (e.g., family functioning, asthma routines, asthma severity) differed by child age. METHODS: Participants included 192 children with asthma (5-12 years) and their caregivers. Both children and caregivers completed questionnaires at an initial research session. Family functioning was determined from a mealtime observation that occurred in family homes. RESULTS: Child age moderated the association between asthma severity and child QOL and between routine burden and QOL in children with asthma. Post hoc probing analyses revealed that among older children, QOL levels were lower in the presence of worse asthma severity and more routine burden. CONCLUSIONS: Findings suggest that associations between asthma severity, routine burden, and QOL may differ by child age. Treatment programs and health-care recommendations addressing QOL in children with asthma may need to be tailored to address differences in factors associated with QOL by child age.

Parental perception of child weight in the first two years-of-life: a potential link between infant feeding and preschoolers' diet.

Approximately 23% of preschoolers are overweight or obese. Establishing a healthy dietary lifestyle at an early age can improve later child diet and body weight. This study examined the determinants of past infant feeding practices that do not follow standard feeding recommendations (breastfeeding for less than 6 months duration, cow's milk prior to the first year of age and solid foods at or before 4 months of age). It also examined the role of parental perception of child weight in the first 2 years-of-life on past infant feeding practices as well as current child diet and body weight. Families of 497 preschoolers aged 22-63 months (39.0 ± 8.2) were recruited from 30 child care centers in East-Central Illinois. Main findings indicate that past infant feeding practices were common and varied by socio-demographic factors including race/ethnicity, parental education and child gender. Children perceived as overweight in the first 2 years-of-life tended to breastfeed for lesser duration. Additionally, the majority (79.8%) of preschoolers who were classified as overweight using BMI percentile were perceived as non-overweight by the parent in the first 2 years-of-life. Mean daily total fatty/sugary food intake was higher among those perceived to be non-overweight in the first 2 years-of-life. These findings have identified parental perception of child weight in the first 2 years-of-life as a modifiable risk factor for unhealthy child diet and obesity among preschoolers.

Identifying elevated child weight from 3 to 24 months: Early transitions into nonparental care and to solid foods.

BACKGROUND: Early entry into nonparental care (NPC) and introduction to solid foods (ITS) have been linked to elevated weight, however, little research exists on the combined influence of these transitions on child weight over time. OBJECTIVES: Identify groups of children based on early NPC and ITS timing and examine whether NPC-ITS groups differentially affect child weight over time. METHOD: Data were drawn from STRONG Kids2 (n = 468). Primary predictors include NPC (by 3M)-ITS (< or ≥6M) groups; outcome variables include child weight-for-length/height z-scores (WFL/WFHz) (3, 12, 18, and 24 months). Multilevel regression was used to examine the NPC-ITS groups as predictors of child WFL/WFHz. RESULTS: Six groups were identified: 27% Parental Care-ITS before 6M, 31% Parental Care-ITS after 6M, 12% Daycare-ITS before 6M, 14% Daycare-ITS after 6M, 10% Kincare-ITS before 6M, and 7% Kincare-ITS after 6M. Children who were in daycare (regardless of ITS) or kincare-ITS before 6M demonstrated the highest WFL/WFHz over time, compared to their parental care counterparts. CONCLUSIONS: NPC-ITS combinations on child WFL/WFHz across the first 2 years of life highlight the need for a partnership approach among parental and nonparental caregivers to support the feeding of infants throughout the transition to solid foods.

Western, Healthful, and Low-Preparation Diet Patterns in Preschoolers of the STRONG Kids2 Program.

OBJECTIVE: Identify and describe diet patterns of children during early childhood using confirmatory factor analysis (CFA). DESIGN: Longitudinal data were drawn from the STRONG Kids 2 program. PARTICIPANTS: Mothers were surveyed about their child's diet at 24 (n = 337), 36 (n = 317), and 48 (n = 289) months old. VARIABLES MEASURED: The Block Food Frequency Questionnaire for children aged 2-7 years was used to derive diet patterns; 23 food groups were created for analyses. ANALYSIS: Principal component analysis was used to obtain preliminary factor loadings, and loadings were used to form a priori hypotheses for CFA-derived diet patterns. Independent samples t tests were used to compare food groups, nutrient intakes, and child and family characteristics by CFA pattern scores above vs at/below the median. RESULTS: Three diet patterns consistently emerged: (1) processed meats, sweets, and fried foods; (2) vegetables, legumes, and starchy vegetables; and (3) grains, nuts/seeds, and condiments (only 24 and 36 months). Patterns were related to differences in added sugars, dietary fiber and potassium intakes, maternal education, and household income. CONCLUSIONS AND IMPLICATIONS: Opposing healthful vs Western patterns, extant in child and adult literature, were observed across all ages. The third pattern differed between 24/36 and 48 months, representing a potential shift in food choices or offerings as children age.

Context matters in pediatric obesity: commentary on innovative treatment and prevention programs for pediatric overweight and obesity.

This commentary reviews the 9 articles in the Special Issue on Innovative Treatment and Prevention Programs for Pediatric Overweight and Obesity. Taking a socio-ecological perspective, contextual factors such as characteristics of the child, family, community, and culture are offered as ways to improve treatment and prevention programs. Using a more tailored approach that takes into account individual differences in family communication patterns and problem solving is warranted. Pediatric psychologists are urged to consider the role of prevention and targeted efforts during early childhood to reduce the prevalence of childhood obesity.

Longitudinal changes in home food availability across the first 3 years of life and associations with family context predictors.

Background: There is limited research tracking changes in home food availability during the first 3 years of life and whether the family context influences these changes. Objective: This study examined changes in and predictors of home food availability across the first 3 years of life. Design: This study utilized longitudinal data from the STRONG Kids2 birth cohort from the target child at 6 weeks to 36 months postpartum. Participants: Mothers of 468 children were surveyed at 6 weeks, 3, 12, 24, and 36 months postpartum. Methods: Home observations were completed by trained research assistants to complete the presence of foods in the home. The primary outcomes were the availability of 10 food groups and scores from the Home Food Inventory (HFI), including dairy (regular fat), dairy (reduced fat), processed meats, other meats and non-dairy protein, savory snacks, vegetables, vegetables (no potatoes), and three obesogenic scores. Repeated measures ANOVA were used to examine changes in the HFI food groups and obesogenic scores over time. Multilevel regressions were conducted to examine whether the presence of an older sibling, entry into childcare, and mother's return to full-time work were associated with the HFI. Results: Significant changes were detected for dairy (regular fat), other meats and non-dairy protein, savory snacks, vegetables, vegetables (no potatoes), and all obesogenic scores across time. A linear trend occurred for most HFI groups, however, the third obesogenic score (without milk and cheese) was highest at 3 months, declined at 12 months, and then slowly increased from 12 to 36 months years. The presence of an older sibling was a consistent predictor of the HFI groups over time. Entry into childcare was only associated with the availability of processed meats. Conclusion: The availability of food types shift as children age and their dietary needs alter. It is important to consider the whole family context such as the presence of older siblings whose dietary needs may differ from younger children. Future efforts are warranted to consider changes in food availability among diverse samples and different family structures.

The Relationship Between Maternal and Infant Sleep Duration Across the First Two Years.

OBJECTIVES: The first objective of this study was to determine how mother-infant sleep duration is related across the first 2 years of life. The second objective was to determine whether these relationships change across the first 2 years of life. The third objective was to understand demographic and health predictors of the relationship between maternal and child sleep. METHODS: Parents of 464 infants from the STRONG Kids 2 study reported their own and infants' nocturnal sleep duration and other health information (i.e., breastfeeding) at 3, 12, 18, and 24 months postpartum. RESULTS: Latent transition models revealed 2 mother-infant sleep profiles exist at 3 to 24 months. The low maternal sleep ( LMS ) pattern was characterized by lower maternal sleep duration than the recommended amount and lower infant sleep duration. The average maternal sleep ( AMS ) pattern was characterized by average maternal sleep duration meeting the recommended standard and average infant sleep duration. Approximately half of the mothers who started in the LMS profile transitioned to the AMS profile after 12 months postpartum. The sleep profiles stabilized after 12 months postpartum with limited transitions across 12 to 24 months. More infant-signaled nighttime wakings, later bedtimes, more infant sleep problems, and more exclusive breastfeeding were predictors of being in the LMS profile. CONCLUSION: Mother-infant sleep profiles stabilized after age 12 months, and mother-infant sleep profiles are driven by infant sleep quality during the night. The findings suggest the need to establish a healthy sleep routine for mothers and infants in the first year of life to promote longer-term sleep hygiene.
