Diet and Physical Activity by Prediabetes Status Among U.S. Adolescents: National Health and Nutrition Examination Survey, 2007-2018.

Background: Prediabetes among adolescents is on the rise, yet it is unclear if modifiable risk factors vary by prediabetes status. Methods: This study examined associations between diet (primary objective) and physical activity (secondary objective) by prediabetes status among U.S. adolescents (12-19 years) who participated in the National Health and Nutrition Examination Survey from 2007-2018. Differences in Healthy Eating Index (HEI)-2015-2020 scores (total and 13 component scores), nutrients of public health concern, and physical activity were examined by prediabetes status (no prediabetes vs. prediabetes). Results: Adolescents (n = 2,487) with prediabetes had significantly lower whole grains component scores and intakes of vitamin D, phosphorus, and potassium (all p < .05), than adolescents without prediabetes. Physical activity levels were not optimal for either group, there were no differences by prediabetes status (n = 2,188). Conclusion: Diabetes prevention interventions for adolescents are needed and should promote a healthy diet target and encourage physical activity.

Adolescent Independent Eating Occasions, Dietary Intake, and Parenting Practices During the COVID-19 Pandemic: A Qualitative Study of Parents and Adolescents From Households With Low Income.

OBJECTIVE: Examine how experiencing the coronavirus disease 2019 (COVID-19) pandemic influenced adolescent independent eating occasions (iEOs) and iEO-related parenting practices from the perspective of parents and adolescents METHODS: Cross-sectional remote interviews were conducted for this basic qualitative research study. Participants were a purposive sample of multiracial/ethnic adolescents aged 11-14 years and their parents from households with low income (n = 12 dyads) representing 9 US states. The main outcome measures were iEOs and iEO-related parenting practices. Data were analyzed using directed content analysis. RESULTS: About half of the parents indicated that their adolescents had more iEOs during the COVID-19 pandemic and that there were changes in the types of foods consumed during iEOs. In contrast, most adolescents indicated their iEOs had not changed remarkably in frequency or foods consumed since the onset of the pandemic. Most parents reported no change in how they taught their adolescents about healthy food, the rules for foods/beverages permitted during iEOs, or how they monitored what their adolescents ate during iEOs; adolescent reports were in general agreement. Most parents indicated that family members were home together more often during the pandemic, which increased cooking frequency. CONCLUSIONS AND IMPLICATIONS: The effect of the COVID-19 pandemic on adolescents' iEOs varied, and the parenting practices used to influence iEOs remained stable during the pandemic. Families experienced having more time together and cooking at home more often.

Mixed-Methods Evaluation of Father Participation in an Adolescent Obesity Prevention Program With Multiple Delivery Methods.

Padres Preparados, Jóvenes Saludables was a Latino family-based obesity prevention intervention implemented from 2017 to 2020 across eight programs in-person only, in a blended format (online/in-person), and online only. The intervention aimed to enhance father parenting skills to improve adolescent diet and activity behaviors. Mothers were encouraged to attend. Factors associated with participation were explored using a mixed-methods, qualitative (focus group/individual interviews by Zoom) and quantitative (process evaluation) design. Eleven focus group and 24 individual interviews were completed after participation with 24 fathers, 27 mothers, and 40 adolescents with responses not sorted by delivery method before analysis. Binomial logistic regression models examined associations between fathers' program completion and predictor variables of delivery characteristics, father demographic characteristics, and family attendance patterns. Parents were married (96% fathers, 76% mothers), had low income, a high school education or less (68% fathers, 81% mothers), and had lived in the United States a mean of 19 years. Parents were motivated to participate to improve health, and to be involved with and improve communication with their child. Common barriers to participation were work and life priorities and programmatic factors including scheduling conflicts and technological issues. Participation was greater for fathers attending sessions in-person compared with online only (OR = 11.6). Fathers were more likely to participate if they attended sessions with family members vs. not attending with family members (OR = 7.2). To maximize participation, findings suggest involving multiple parents/caregivers and adolescents, addressing contextual and programmatic barriers, and promoting benefits of better health and relations with family members.

Parenting Practices Are Associated With Adolescent Food Choices During Independent Eating Occasions.

BACKGROUND: Frequency of independent eating occasions (iEOs) has been linked to intake of unhealthy foods and overweight or obesity among adolescents. Parenting practices involving modeling healthy food intake and making healthy foods available have been associated with healthy food intake among adolescents; however, little is known about these associations during iEOs. OBJECTIVE: To determine whether parenting practices involving structure (monitoring, availability, modeling, and expectations), lack of structure (indulgence), and autonomy support reported by adolescents or parents were associated with adolescent iEO intake of junk foods, sugar-sweetened beverages (SSBs), sugary foods, and fruit and vegetables. DESIGN: Cross-sectional study measuring parenting practices and adolescent iEO food choices via an online survey and adapted food frequency questionnaire. PARTICIPANTS/SETTING: Parent/adolescent dyads (n = 622) completed surveys (November-December 2021) using a national Qualtrics panel database. Adolescents were 11 to 14 years of age and had iEOs at least weekly. MAIN OUTCOME MEASURES: Primary measures included parent- and adolescent-reported frequency of food parenting practices and adolescent-reported iEO intake of junk foods, sugary foods, SSBs, and fruits and vegetables. STATISTICAL ANALYSES PERFORMED: Multivariable linear regression models were used to examine associations between parenting practices and iEO intake of foods/beverages, adjusting for adolescent's age, sex, race and ethnicity, iEO frequency, parent's education and marital status, and household food security status. Bonferroni multiple comparison corrections were conducted. RESULTS: More than half of parents were female (66%) and 35 to 64 years of age (58%). Adolescents/parents identified as White/Caucasian (44%/42%), Black/African American (28%/27%), Asian (21%/23%), and Hispanic ethnicity (42%/42%). Positive associations were observed among adolescent-reported and parent-reported autonomy support, monitoring, indulgence and expectations parenting practices, and adolescent-reported daily iEO intake frequencies of junk foods, sugary foods, and fruits and vegetables (P < 0.001). CONCLUSIONS: Structural and autonomy support parenting practices were positively associated with both healthy and unhealthy iEO food intake by adolescents. Interventions to improve adolescent iEO intake could promote positive practices associated with healthy food consumption.

Diabetes prevention program outcomes by in-person versus distance delivery mode among ethnically diverse, primarily lower-income adults.

Objective: Physical activity and weight loss outcomes of a diabetes prevention program were compared for ethnically diverse adults, with the majority participating in public assistance programs. Outcomes were compared for those who completed the program in person versus by distance delivery. Methods: A two-group, pre-post study design compared National Diabetes Prevention Program outcomes based on in-person delivery (2018-2020 pre-COVID-19 pandemic, n = 47) and distance delivery (after March 2020, n = 31). Outcomes were measured or self-reported depending on the delivery method. Linear mixed models with a random intercept for coach and covariates were used to assess delivery mode group differences in percent weight loss and weekly physical activity minutes. Results: Completion rates were similar by in-person versus distance delivery mode (57% vs. 65%). Among those who completed the program, the mean age was 58 years, the mean baseline body mass index was 33, and 39% were Hispanic. The majority were female (87%), participating in a public assistance program (63%), and living in a micropolitan area (61%). Percent weight loss was greater in the distance delivery group (7.7%) compared to the in-person group (4.7%) in the unadjusted analysis (p = 0.009) but not when adjusted for covariates. No differences were observed in adjusted weekly physical activity minutes between the in-person (219 min) versus the distance group (148 min). Conclusions: No differences were observed by delivery mode in percent weight loss or weekly physical activity minutes, indicating that distance delivery does not compromise program effectiveness.

Factors Associated with Fathers' Attendance in a Latino Family Obesity Prevention Program.

Community-based programs may contribute to Latino pediatric obesity prevention; however, attendance remains low. This study aimed to identify factors associated with Latino father/male caregiver attendance in family-based adolescent obesity prevention programs conducted as part of a randomized controlled trial. The study used cross-sectional data from 137 fathers in the program, involving eight weekly sessions to improve their children's energy balance-related behaviors. Evaluation data were collected at baseline and post-intervention. Fathers in a waitlisted control group attended sessions after post-intervention data collection. Attendance patterns were identified using cluster analysis: consistently high attendance (50% of fathers), declining attendance (19%), and non-attendance (31%) clusters. Multinomial logistic regression was used to examine associations between attendance patterns and variables. Compared to consistently high attendance, fathers in the non-attendance cluster were more likely to have been assigned to the control group (odds ratio [OR] = 7.86, p < 0.001), tended to have lower household income (OR = 2.50, p = 0.098), and attended the program at a site where the program occurred weekdays (OR = 0.35, p = 0.094). Maintaining contact during waiting periods and providing sessions online or during weekends could reduce non-attendance by enhancing convenience for low-income fathers working multiple jobs.

Padres Preparados, Jóvenes Saludables: A Randomized Controlled Trial to Test Effects of a Community-Based Intervention on Latino Father's Parenting Practices.

Parenting practices have been associated with adolescent lifestyle behaviors and weight status. Evidence is limited regarding the efficacy of interventions to address father influences on adolescent lifestyle behaviors through availability and modeling practices. Therefore, the purpose of this study was to evaluate changes in father parenting practices after Latino families with adolescents participated in the Padres Preparados Jóvenes Saludables (Padres) program. Time-1 (baseline) and Time-2 (post-intervention) data were used from Latino father/adolescent (10-14 years) dyads enrolled in the Padres two-arm (intervention vs. delayed-treatment control group) randomized controlled trial in four community locations. The program had eight weekly, 2.5-h experiential learning sessions on food preparation, parenting practices, nutrition, and physical activity. Two types of parenting practices (role modeling and home food availability) were assessed by father report via questionnaire for each of 7 lifestyle behaviors, for a total of 14 parenting practices. Linear regression mixed models were used to evaluate the intervention effects. A total of 94 father/adolescent dyads completed both Time-1 and Time-2 evaluations. Significant positive intervention effects were found for frequencies of fruit modeling (p = 0.002) and screen time modeling (p = 0.039). Non-significant results were found for the other 12 father parenting practices.

Feasibility of a remotely delivered program to prevent Latino adolescent obesity in the Midwestern USA.

Adolescent obesity prevention programs focusing on Latino fathers may be useful to address Latino adolescent obesity. Adolescent obesity has become an urgent issue because of the coronavirus disease 2019 pandemic, with limited ability to deliver prevention programs in-person. This study aimed to assess the feasibility of a community-based, adolescent obesity prevention program for Latino father-adolescent dyads delivered remotely, adapted from the in-person Padres Preparados, Jóvenes Saludables program. A quasi-experimental design was used to assess the feasibility of the remotely delivered program based on criteria adapted from other feasibility studies of community-based health promotion programs for Latino families. Father-adolescent dyads were recruited at two sites in a Midwestern state during 2020; mothers were also encouraged to participate. Recruitment met the feasibility criteria (65 families expressed interest between August and October) with 26 families participating in this study. The retention ratio (percentage of participants who completed a post-session survey to those who completed the baseline survey) among fathers was acceptable (77%), while a lower percentage of adolescents were retained (68%). The session attendance ratio (number of sessions attended of the eight total sessions offered) was higher among adolescents (88%) and lower among fathers (68%) compared to the criteria. Satisfaction ratings (≥88%) and completeness of data collection at both baseline and post-session survey (≥76%) were acceptable. Favorable results were obtained for parent outcomes, while adolescent outcomes were not favorably changed. This remotely delivered adolescent obesity prevention program was feasible for Latino fathers; however, additional engagement with adolescents may be needed.

Adolescent obesity became a more urgent issue because of the coronavirus disease 2019 pandemic with less physical activity under lockdown, more food insecure families and limited in-person access to programs. Our study concluded that a remotely delivered version of a community-based, adolescent obesity prevention program for Latino father­adolescent dyads (the Padres Preparados, Jóvenes Saludables program) was feasible based on participation, satisfaction and parent outcomes. Additional engagement in activities to improve adolescent health behaviors may be needed to improve the overall effectiveness of the program.

Food Away from Home Frequency, Diet Quality, and Health: Cross-Sectional Analysis of NHANES Data 2011-2018.

The consumption of meals prepared away from home (FAFH) in the U.S. has been commonly linked to overall poorer diet quality; however, less is known about the relationship with health parameters. The aim of this cross-sectional study was to assess the diet quality and health parameters of adults who reported the frequency of obtaining or eating FAFH using a combination of four 2-year cycles of National Health and Nutrition Examination Survey (NHANES, 2011−2018) data. Data from 14,999 adults aged 20 to 65 years were used to examine the associations between diet and health outcomes and the weekly frequency of FAFH. Multivariable regression models were used to compare Healthy Eating Index-2015 (HEI-2015) scores by FAFH frequency, adjusting for sociodemographic variables. Adults with more frequent FAFH meals were more likely to be younger, male, lower-income, and unmarried. Total HEI-2015 scores and component scores for greens and beans, total and whole fruits, whole grains, saturated fats, and added sugars were significantly lower in those consuming >2 FAFH meals/week vs. ≤2 FAFH meals/week. BMI and waist circumference tended to be higher for women having more frequent FAFH meals. More frequent FAFH meals among adults were associated with poorer diet quality and weight outcomes, building on results from earlier studies.

How is weight teasing cross-sectionally and longitudinally associated with health behaviors and weight status among ethnically/racially and socioeconomically diverse young people?

BACKGROUND: Weight stigma is prevalent among young people and harmful to health. The current study used a health equity lens to examine cross-sectional and longitudinal associations between experiencing weight teasing (a form of weight stigma) with a range of weight-related health behaviors and weight status in an ethnically/racially and socioeconomically diverse sample of young people. We also assessed whether ethnicity/race and adolescent socioeconomic status (SES) operated as effect modifiers in these relationships. METHODS: Adolescents (n = 1568) were enrolled in EAT 2010-2018 (Eating and Activity over Time) and followed into young adulthood. Weight teasing; screen time; moderate-to-vigorous physical activity (MVPA); sleep duration; breakfast frequency; fruit, vegetable, sugar-sweetened beverage (SSB), and fast-food intake; and body mass index (BMI) were assessed at baseline (mean age = 14.4 years) and eight-year follow-up (mean age = 22.2 years). Multivariate linear regression estimated marginal means and 95% confidence intervals. All analyses adjusted for BMI and sociodemographic characteristics. RESULTS: Weight teasing was cross-sectionally associated with longer screen time, shorter sleep duration, and higher BMI during adolescence; and cross-sectionally associated with shorter sleep duration, lower breakfast frequency, higher fast-food intake, higher SSB intake, and higher BMI during young adulthood. In the longitudinal analyses, weight teasing was not associated with health behaviors but did predict higher BMI (teased: 28.2 kg/m2, not teased: 26.4 kg/m2, p < 0.001). White and higher adolescent SES subgroups had higher MVPA, more frequent breakfast intake, lower fast-food intake, and lower BMI than their respective counterparts. The relationships between weight teasing and health behaviors and weight status were largely consistent across ethnic/racial and adolescent SES subgroups. CONCLUSIONS: Findings add to growing evidence that weight-based mistreatment poses a threat to weight-related health and that young people across ethnic/racial and SES subgroups are vulnerable to the negative effects of weight teasing. Limitations include attrition at follow-up and the self-reported nature of many measures. Results suggest a need for increased attention to existing recommendations to reduce weight stigma in young people from diverse ethnic/racial and socioeconomic backgrounds including training for healthcare providers to better equip them to address the harms of weight teasing and foster more compassionate care to promote health-supporting behaviors in young people.

Relationship between Family Racial/Ethnic Backgrounds, Parenting Practices and Styles, and Adolescent Eating Behaviors.

Obesity is more prevalent among racial minority children in the United States, as compared to White children. Parenting practices can impact the development of children's eating behaviors and habits. In this study, we investigated the relationships among racial/ethnic backgrounds, parenting practices and styles, and eating behaviors in adolescents. Fifty-one parent-adolescent dyads were interviewed to characterize parenting practices and styles, as well as the consumption of dairy, fruits and vegetables, and unhealthy snacks. Height and weight were measured to calculate parent BMI and adolescent BMI-for-age percentiles. Three parenting practice categories-modeling, authoritative, and authoritarian-were found to be related to race/ethnicity. A higher score in authoritarian parenting practices was related to higher BMI percentiles among African American adolescents, whereas a higher score in monitoring practices was related to lower BMI percentiles among non-Hispanic White adolescents. Modeling, reasoning, and monitoring led to higher consumption of fruits and vegetables among adolescents; however, the consumption of unhealthy snacks was higher with rule-setting and lower with reasoning and authoritative practices. Finally, an analysis of the relationships between environmental factors and snack intake showed that adolescents consumed significantly more unhealthy snacks when performing other activities while eating. In conclusion, the findings from this study suggest that families' racial heritages are related to their parenting practices, BMI percentiles, and their adolescents' food consumption and eating behaviors. The results of this study can be used to develop and improve adolescent nutrition education and interventions with consideration of their racial/ethnic backgrounds.

Collecting, Using, and Reporting Race and Ethnicity Information: Implications for Research in Nutrition Education, Practice, and Policy to Promote Health Equity.

This report will describe approaches for collecting, analyzing, and reporting race and ethnicity information in nutrition education and behavior research, practice, and policy to advance health equity. Race and ethnicity information is used to describe study participants and compare nutrition and health-related outcomes. Depending on the study design, race and ethnicity categories are often defined by the research question or other standardized approaches. Participant self-reported data are more acceptable than researcher adjudicated identification data, which can add bias and/or error. Valid methods to collect, use, and report race and ethnicity information are foundational to publication quality, findings of value, contribution to the knowledge base, and health equity.

Serum ß-carotene concentrations are associated with self-reported fatty acid intake in United States adults from the National Health and Examination Surveys.

Bioavailability of dietary ß-carotene (BC) is dependent on dose, quantity, dispersion, and presence of fat in the diet. Fats are comprised of a variety of fatty acids, which may impact the bioavailability of carotenoids. However, there is a gap in research on whether specific fatty acid classes affect serum BC concentrations in population samples. The primary objective of this study was to assess the association between reported fat and fatty acid intake and serum BC concentrations utilizing data from the National Health and Nutrition Examination Surveys (NHANES) 2003-2006. Data from 3278 NHANES participants 20-85 years old were analyzed to estimate the relationships between serum BC concentrations and reported saturated (SFA), monounsaturated (MUFA), and polyunsaturated (PUFA) fatty acid intakes. Multiple linear regression estimated ln(serum BC) based on reported fatty acid intakes adjusted for age, sex, race/ethnicity, and reported dietary BC intakes. Mean and standard error (SE) for serum BC concentrations were 14.31 ± 0.05 µg/dl. Means and SE for total fat, SFA, MUFA, and PUFA were 85.7 ± 1.3, 26.9 ± 0.4, 31.1 ± 0.5, and 17.8 ± 0.4 g, respectively. There was a significant trend for association between serum BC and reported total fat intakes (r = -0.002, p < 0.0001), but the association was not strong. Multiple linear regression showed positive associations between serum BC concentrations and higher reported dietary PUFA consumption. PUFA alpha-linolenic acid intakes are positively associated with serum BC concentrations, while MUFA palmitoleic acid and SFA stearic acid were inversely associated with serum BC. The inverse association between MUFA and SFA suggests there may be multiple post-digestion factors affecting serum carotenoid concentrations.

Impacts of A Taste of African Heritage: A Culinary Heritage Cooking Course.

OBJECTIVE: To examine changes in cooking and dietary behaviors and health outcomes following participation in A Taste of African Heritage, a culinary heritage cooking course. DESIGN: One group, pre-post program design, surveys, and physical assessments. SETTING: Community centers, churches, health care settings, homes, and housing complexes. PARTICIPANTS: Participants (n = 586, 84% women) were recruited by partner organizations from 2013-2018 across 21 states and the District of Columbia. INTERVENTION(S): A 6-week cooking curriculum that teaches history, nutrition, and cooking techniques to reconnect participants with the vibrant, healthy traditions of the African Diaspora. MAIN OUTCOME MEASURE(S): Weekly frequency of cooking, food group intake, and exercise assessed by surveys, measured weight, waist circumference, and blood pressure. ANALYSIS: Linear and logistic mixed-effects models with random intercepts for participant and teacher, sex and site type as covariates comparing pre-post physical measurements and binary behavioral outcomes, P < 0.0033 for statistical significance after Bonferroni correction. RESULTS: Intake frequencies of fruit, vegetable, and greens and exercise frequency were improved from preprogram to postprogram (all P < 0.0021). Weight, waist circumference, and systolic blood pressure were also improved from preprogram to postprogram (all P <0.0001). CONCLUSIONS AND IMPLICATIONS: Participation in A Taste of African Heritage was associated with positive behavior changes and health outcomes. Integrating cultural heritage and behaviors are positive components to connect participants to healthy old ways or traditions.

Frequency of Meals Prepared Away from Home and Nutrient Intakes among US Adolescents (NHANES 2011-2018).

Frequency of consuming foods prepared away from home has been associated with lower diet quality among adults and adolescents in several earlier studies. Nutrient and food group intake and Healthy Eating Index (HEI)-2015 scores were compared among a U.S. nationally representative sample of adolescents (12-19 years, n = 3975) by frequency of consuming food prepared away from home ≤2 times/week (n = 2311) versus >2 times/week (n = 1664) using National Health and Nutrition Examination Survey (NHANES) data from 2011-2018. Regression analyses were used to compare intakes among adolescents by frequency of eating meals prepared away from home adjusting for covariates. Older (16-19 years) vs. younger (12-15 years) adolescents and those from homes with higher vs. lower family income to poverty ratios had greater frequency of eating meals prepared away from home. Intakes of nutrients of concern for adolescents including choline, vitamin D, potassium, magnesium, fiber, phosphorus, folate, iron, and total HEI-2015 scores and component scores for total vegetables, and greens and beans were lower among adolescents who consumed meals prepared away from home more vs. less often. However, no differences were noted among food group intakes considered good sources of nutrients of concern such as total fruit, total vegetables, whole grains, and total dairy, except for beans and peas by frequency of eating foods prepared away from home. Greater frequency of eating foods prepared away from home was associated with lower diet quality among adolescents in a nationally representative sample of U.S. adolescents.

Nutrient and Food Group Intakes among U.S. Children (2-5 Years) Differ by Family Income to Poverty Ratio, NHANES 2011-2018.

Family income may influence nutrient and food group intakes among preschool children, thus increasing risk of nutrient deficiencies. This study compared nutrient and food group intakes and diet quality among a U.S. sample of children 2-5 years of age by family income to poverty ratio (PIR) based on National Health and Nutrition Examination Survey (2011-2018) data (n = 2249). Regression analyses were used to compare dietary intakes based on proxy-reported 24-h dietary recalls and Healthy Eating Index-2015 total scores by low PIR versus mid-high PIR levels adjusted for covariates. PIR levels varied by child race/ethnicity and household reference person's sex, marital status, and education. More than half of the children in the low PIR group (56%) were reported to have received WIC benefits in the past year. Marginally lower calcium (p = 0.008) and lower fiber intakes, lower total HEI-2015 scores, and lower intakes of fruits and whole grain foods (all p < 0.007) were observed among children in low PIR households compared to mid-high PIR households. However, iron intakes were higher (p = 0.0003) among children in low PIR households compared to mid-high PIR households. Lack of other differences in nutrient and food group intakes may be attributable to WIC benefits.

Adolescent-Reported Latino Fathers' Food Parenting Practices and Family Meal Frequency Are Associated with Better Adolescent Dietary Intake.

Most studies of food-related parenting practices, parental meal involvement, and adolescent dietary intake have focused on maternal influences; studies of paternal influences, particularly among marginalized groups, are lacking. This study examined lower-income, Latino fathers' food parenting practices and involvement in planning meals, buying/preparing foods, and family meal frequency, separately and in combination, to identify relationships with adolescent food intake. Baseline data were used from Latino adolescents (10-14 years, n = 191, 49% boys) participating with their fathers in a community-based overweight/obesity prevention intervention. Fathers reported sociodemographic characteristics. Adolescents reported frequency of fathers' food parenting practices, fathers' food/meal involvement, and family meals and participated in 24 h dietary recalls. The analysis included regression models using GLM (generalized linear mixed model) and PLM (post GLM processing) procedures. Most fathers were married, employed full-time, and had annual incomes below USD 50,000. Favorable fathers' food parenting practices were associated with adolescent intake of more fruit and vegetables and fewer sugar-sweetened beverages, sweets/salty snacks, and less fast food (p < 0.05 or p < 0.01). No independent effects of family meal frequency or fathers' food/meal involvement were observed on adolescent dietary outcomes. Additional analyses showed favorable food parenting practices in combination with frequent family meals were associated with adolescents having a higher intake of fruit (p = 0.011). Latino fathers can have an important positive influence on adolescent dietary intake.

Influence of paternal general parenting on Latino early adolescents' energy balance-related behaviours and interactions with behaviour-specific parenting practices.

OBJECTIVE: To investigate the influence of general parenting dimensions on adolescents' energy balance-related behaviours (EBRB) and its interactions with behaviour-specific parenting practices based on Darling and Steinberg's contextual model of parenting style. DESIGN: Multiple linear regression analyses and the Hayes PROCESS procedure to analyse self-reported cross-sectional survey data. SETTING: In-person survey. PARTICIPANTS: Latino early adolescents and their fathers (n 225 dyads) recruited using convenience sampling from metropolitan areas of north-central USA. RESULTS: Both paternal parenting dimensions of warmth and autonomy granting were positively associated with adolescents' fruit intake, vegetable intake and physical activity. Coercive control was positively associated with adolescents' sugary drink intake and sweets/salty snack intake. These associations were predominantly mediated by the parenting practices of setting expectations/allowances, role modelling, and managing availability and accessibility for corresponding EBRB. After adjusting for parenting practices, paternal warmth was inversely associated with adolescents' screen time, paternal autonomy was positively associated with sugary drink intake, and both paternal warmth and autonomy granting were positively associated with adolescents' fast food intake. In addition, positive associations between fathers' parenting practices and adolescents' sugary drink intake were significantly stronger among those who perceived high v. low levels of paternal warmth and autonomy granting. CONCLUSIONS: Paternal warmth and autonomy granting showed mixed effects on adolescents' EBRB, and coercive control showed undesirable relationships with adolescents' dietary intake via interactions with behaviour-specific parenting practices. Lifestyle intervention programmes for Latino adolescents need to consider incorporating paternal parenting education components.

Differences in reporting food insecurity and factors associated with differences among Latino fathers and mothers.

BACKGROUND: Food security status has been assessed as a representative score for households; however, different members in the same household may perceive and report food insecurity differently. A high prevalence of food insecurity has been reported among Latino households, therefore understanding differences in reporting food insecurity by Latino father-mother dyads may improve accuracy of assessment and plans to address food insecurity. This study aimed to 1) determine demographic characteristics and/or food-related factors associated with perceptions of food security status among Latino father-mother dyads, and 2) identify factors associated with discordance in perceptions of food insecurity between dyads. METHODS: Baseline data were used from a community-based, youth obesity prevention program among Latino families (n = 106 father-mother dyads). Food security was assessed with a 2-item food insecurity screen. Logistic regression models were used to evaluate associations between reporting food security status and predictor variables for fathers, mothers, and dyad-discordant responses. RESULTS: Food insecurity was reported by 39% of fathers and 55% of mothers. Adjusted odds of reporting food insecurity were significantly higher for fathers perceiving their neighborhood was unsafe vs. safe (OR: 3.7, p < 0.05) and reporting lower vs. higher household income (OR: 3.2, p < 0.05). Adjusted odds of reporting food insecurity were significantly higher for mothers perceiving their neighborhood was unsafe vs. safe (OR: 4.1, p < 0.01) and reporting lower vs. higher home availability of fruit and vegetable (OR: 5.5, p < 0.01). Dyad discordance in reporting food security status occurred in 24% of the dyads. Adjusted odds of dyad discordant reports of food insecurity status were significantly higher for dyads reporting discordant responses regarding previous nutrition education (OR: 3.4, p < 0.05) and higher home fruit and vegetable accessibility (OR: 3.1, p < 0.05) compared to dyads reporting concordant responses. Among the 28 dyads who reported discordant nutrition education participation, 21 reported that fathers had never participated but mothers had participated more than once. CONCLUSIONS: Differential factors were associated with reporting food security among Latino father-mother dyads. Nutrition education for fathers that improves awareness of home food supplies and a better understanding of how food accessibility influences maternal perceptions may improve dyad discordance in reporting household food security.

Skin Carotenoid Scores Assessed with Reflection Spectroscopy Are Associated with Self-Reported Fruit and Vegetable Intake Among Latino Early Adolescents.

BACKGROUND: Latino early adolescents have a high prevalence of overweight and obesity. Interventions to address healthy eating among Latino youth frequently focus on fruit and vegetable (FV) intake. Reflection spectroscopy assessed skin carotenoid (SC) levels has been proposed as an easy, noninvasive method to evaluate FV intake, but validation studies involving ethnically diverse youth are lacking. OBJECTIVE: This study aimed to assess the association between reflection spectroscopy-measured SC scores and self-reported FV intake among low-income, urban, Latino early adolescents, controlling for potential confounding factors. DESIGN: This study was a cross-sectional secondary analysis of baseline data from a community-based intervention program (Padres Preparados, Jóvenes Saludables) involving Latino fathers and adolescents to improve paternal parenting practices and youth energy balance-related behaviors. PARTICIPANTS/SETTING: Participants were 195 low-income, Latino early adolescents (aged 10 to 14 years). Data were collected in the Minneapolis/St Paul metropolitan area from 2017 to 2020 during fall or winter months. MAIN OUTCOME MEASURES: SC scores were measured using reflection spectroscopy, usual intakes of FV and carotenoid compounds were estimated based on the assessment using 24-hour dietary recalls. STATISTICAL ANALYSIS: Multivariable linear regression analyses were used to estimate associations of SC scores and each dietary component and potential confounding factors after assessing variables for inclusion in the analyses. RESULTS: The mean SC score was 225 ± 95. The mean FV and total carotenoid intakes were 3.3 ± 0.5 servings/day and 8,360 ± 786 µg/day, respectively. Higher SC scores were observed among youth who had higher FV (ß = .37 and P < 0.01) or total carotenoid intakes (ß = .31 and P < 0.01). SC scores measured during fall were higher than scores measured during winter. Study participants with higher home FV availability and accessibility had higher SC scores. CONCLUSIONS: Findings supported using SC score as a potential easy-to-use indicator of FV intake among Latino youth with consideration of seasonal variation and home FV availability and accessibility.
