RESUMEN
BACKGROUND: Evidence suggests dietary acculturation can increase obesity and chronic disease risks. However, acculturation effects on diet quality among subgroups of Hispanic Americans is not well studied. OBJECTIVES: Estimating percentages of Hispanic Americans with low, moderate, and high acculturation using 2 proxy measures with different language variables was the first objective. Identifying similarities and dissimilarities in diet quality differences by acculturation level between Mexican Americans and other Hispanic Americans was the second objective. METHODS: The study sample included 1733 Mexican American and 1191 other Hispanic participants aged ≥16 y from National Health and Nutrition Examination Survey 2015-2018. Proxy measures included in the 2 acculturation scales were nativity/United States residence length, immigration age, language spoken at home (home), and language of dietary recall (recall). Replicate 24-h dietary recalls were conducted, and diet quality was assessed using the 2015 Healthy Eating Index. Analyses included statistical methods for complex survey designs. RESULTS: For Mexican Americans, 8%, 35%, and 58% had low, moderate, and high acculturation on the home scale compared with 8%, 30%, and 62% on the recall scale. For other Hispanics, 17%, 39%, and 43% had low, moderate, and high acculturation on the home scale compared with 18%, 34%, and 48% on the recall scale. Similarities between ethnicities included higher acculturation associated with lower intakes of fruits, vegetables, total protein foods, seafood and plant proteins, and saturated fats and greater intake of sodium. Dissimilarities included higher acculturation associated with more whole grains and added sugars intakes and less refined grains intake (Mexican Americans), and less total dairy and fatty acids intakes (other Hispanic Americans). CONCLUSIONS: Higher acculturation is associated with worsening diet quality for fruits, vegetables, and protein foods in all Hispanic Americans. However, associations of higher acculturation with worsening diet quality for grains, added sugars, dairy, and fatty acids were present only in specific subgroups of Hispanic Americans.

BACKGROUND: Evidence suggests that acculturation can increase risks of poor diet, obesity, and chronic diseases. Yet questions remain regarding acculturation proxy measures and associations with diet quality in Asian Americans. OBJECTIVES: Primary objectives included estimating percentages of Asian Americans with low, moderate, and high acculturation using 2 proxy measures of acculturation based on different language variables and determining if diet quality differences existed among acculturation levels using the 2 proxy acculturation measures. METHODS: Study sample included 1275 Asian participants aged ≥16 y from National Health and Nutrition Examination Survey 2015-2018. Nativity/length of United States residence, immigration age, language spoken at home (home), and language of dietary recall (recall) were used as proxy measures for 2 acculturation scales. Replicate 24-h dietary recalls were conducted and diet quality was assessed using 2015 Healthy Eating Index. Statistical methods for complex survey designs were used for analysis. RESULTS: Using home and recall language, 26% compared with 9% of participants were classified with low, 50% compared with 63% with moderate, and 24% compared with 28% with high acculturation. On the home language scale, participants with low and/or moderate acculturation had higher scores (0.5-5.5 points) for vegetables, fruits, whole grains, seafood and plant protein, saturated fats, added sugars, and total 2015 Healthy Eating Index than participants with high acculturation; participants with low acculturation had lower refined grain score (1.2 points) than participants with high acculturation. Results were similar for the recall language scale, except differences between participants with moderate and high acculturation were also observed for fatty acids. CONCLUSIONS: Although percentages of Asian Americans classified with low, moderate, and high acculturation differed between the 2 proxy measures for acculturation, diet quality differences among acculturation groups were remarkably similar between the 2 proxy measures. Hence, use of either language variables may yield comparable results regarding the relationships between acculturation and diet in Asian Americans.

BACKGROUND.: The purpose of this study was to collect updated school food service purchasing practices from K-12 public school food service directors (SFSD) in Mississippi and to determine their current abilities, experiences, and desires to engage in Farm to School (F2S) activities. METHODS.: The online survey was created using questionnaire items from existing F2S surveys. The survey opened in October 2021 and closed in January 2022. Descriptive statistics were used to summarize the data. RESULTS.: Of the 173 SFSD sent email invitations, 122 (71%) completed the survey. The most common fresh fruit and vegetable purchasing practices included Department of Defense Fresh Program (65%) and produce vendor (64%). Forty-three percent of SFSD purchased at least one locally sourced fruit and 40% purchased at least one locally sourced vegetable, while 46% did not purchase any locally sourced foods. The most common challenges for purchasing from farmers included no relationship with farmers (50%) and food safety regulations (39%). Sixty-four percent of SFSD were interested in at least one F2S activity. CONCLUSIONS.: Most SFSD do not purchase local foods directly from farmers and almost half do not purchase any local foods regardless of source. Lack of connection with local farmers is a significant challenge to F2S. Recently proposed framework by USDA for shoring up the food supply chain and transforming the food system may help reduce or remove ongoing challenges to F2S participation.
RESUMEN
BACKGROUND: While research exploring relationships between individual parenting practices and child physical activity (PA) exists, little is known about simultaneous use of practices. Hence, study objectives were to determine patterns of PA parenting practices and their associations with demographic, anthropometric, and PA measures in a large sample of parents and their adolescent children (12-17 years). METHODS: Dyadic survey data from Family Life, Activity, Sun, Health, and Eating (FLASHE), a cross-sectional, internet-based study, conducted in 2014 were analyzed using latent class analysis on 5 PA parenting practices - pressuring, guided choice, expectations, facilitation, and modeling. Self-report model covariates included adolescent age and parent and adolescent sex, body mass index category (based on height and weight), legitimacy of parental authority regarding PA (PA-LPA), and moderate-to-vigorous PA (MVPA). RESULTS: Based on 1166 parent-adolescent dyads, four latent classes were identified representing a continuum of practice use (high to low) - Complete Influencers (26%), Facilitating-Modeling Influencers (23%), Pressuring-Expecting Influencers (25%), and Indifferent Influencers (27%). Compared to dyads with parent underweight/healthy weight, dyads with parent overweight/obesity had 84% higher odds of belonging to Indifferent Influencers. Compared to dyads with adolescent underweight/healthy weight, dyads with adolescent overweight/obesity had 50 and 46% lower odds of belonging to Facilitating-Modeling and Indifferent Influencers. Odds of belonging to Pressuring-Expecting and Indifferent Influencers were less than 1% lower for every 1 min/day increase in parent MVPA and 2 and 4% lower for every 1 min/day increase in adolescent MVPA. Compared to dyads with high parental and adolescent agreement with PA-LPA, dyads with low agreement had between 3 and 21 times the odds of belonging to Facilitating-Modeling, Pressuring-Expecting, or Indifferent Influencers. CONCLUSIONS: Findings suggest that parents utilize distinct patterns of PA practices ranging from use of many, use of some, to low use of any practice and these patterns are differentially associated with parent and adolescent PA. When planning PA interventions, a counseling or intervening approach with parents to use combinations of practices, like facilitation and modeling, to positively influence their adolescents' and possibly their own participation in PA may prove more efficacious than parental pressuring or lack of practice use.

BACKGROUND: Children's food preference and intake patterns are affected by parental child feeding practices. The objective was to determine patterns of food parenting practices regarding junk food and sugary drinks (JS) and investigate their associations with demographic characteristics and dietary intake in a large cohort of parents and their children (12-17 years). METHODS: Dyadic survey data from the cross-sectional, internet-based Family Life, Activity, Sun, Health, and Eating Study, conducted in 2014, were analyzed using latent class analysis to identify patterns of use for six JS parenting practices - negative emotions, restriction, monitoring, availability, modeling, and child involvement - based on parent and child report. Model covariates included self-reported parent and child sex, age (child only), body mass index category (based on height and weight), added sugars intake, and legitimacy of parental authority. RESULTS: Based on 1657 parent-child dyads, five parenting practice patterns were identified representing different levels of practice use - Complete Influencers (28%; reference class), Indifferent Influencers (21%), Negative Influencers (20%), Minimal Influencers (18%), and Disagreeing Influencers (13%). Compared to older child dyads, younger child dyads were less likely to belong to Indifferent and Minimal Influencers (79 and 63% lower odds, respectively). Greater parent added sugars intake increased the odds of belonging to Indifferent and Negative Influencers (4 and 5% higher for every teaspoon increase, respectively) while greater child added sugars intake decreased the odds of belonging to Minimal Influencers (6% lower for every teaspoon increase). Compared to dyads with high scores, dyads with low child scores for legitimacy of parental authority regarding JS were 18 times as likely to belong to Disagreeing Influencers. CONCLUSIONS: The study findings suggest that parents utilize distinct patterns of feeding practices regarding JS ranging from use of many practices, use of some practices, to low use of any practice, with differential associations with parent and child intakes of added sugars. Counseling or intervening with parents to use a mix of structure practices, such as availability and modeling, to positively influence their child's and possibly their own intake of sugary snacks and drinks may prove more efficacious than use of coercive control practices, such as negative emotions.

INTRODUCTION: The Lower Mississippi Delta is characterized by several factors associated with poor diet quality. Our objective was to measure local nutrition environments of pregnant women and their infants who participated in a nutrition and physical activity intervention to assess environmental exposures potentially influencing their dietary habits. METHODS: We measured the nutrition environments of 5 towns in which participants resided by using the Nutrition Environment Measures Survey for grocery stores, convenience stores, full-service restaurants, and fast food restaurants. We used general linear models to test for differences in ratio scores, calculated by dividing each food outlet score by the maximum score possible, among food outlet classes and subclasses. RESULTS: Mean total ratio scores (expressed as percentages) for the Nutrition Environment Measures Survey among 4 classes of food outlets were significantly different from one another except for convenience stores and full-service restaurants. On average, grocery stores (n = 11) had 54% of maximum points possible, followed by full-service restaurants (21%; n = 50), convenience stores (16%; n = 86), and fast food restaurants (8%; n = 119). We found no significant differences in mean total ratio scores among convenience store subclasses. For fast food restaurant subclasses, stand-alone restaurants (n = 81) had 19% of maximum points possible, significantly higher than grocery store delicatessens (6%; n = 8), corner stores that sold fast food (3%; n = 5), and gas stations that sold fast food (4%; n = 25). CONCLUSION: These 5 Lower Mississippi Delta towns scored low on nutrition environment measures associated with healthful eating. Behavioral interventions designed to bring about positive changes in dietary habits of rural residents are needed; however, effects may be minimal if environmental factors supportive of healthful eating are not available.

INTRODUCTION: Our objective was to determine aspects of the built environment that may have contributed to the low levels of physical activity reported in both the gestational and postnatal periods by women participating in a diet and physical activity intervention in the rural Lower Mississippi Delta. METHODS: The built environments of 12 towns were measured by using the Rural Active Living Assessment tools and the Community Park Audit Tool. Correlations between town assessment scores and town size variables were computed by using Kendall τ coefficient. The street distance from a participant's home address to the nearest park was computed by using network analysis in ArcGIS. RESULTS: Rural Active Living Assessment scores were low with mean values between 0% (town policy) and 68% (parks and playgrounds) of the highest possible scores. The mean (standard deviation) number of parks per town was 2.6 (3.2), and 55% of the 31 parks were in the 2 largest towns. Most parks (87%) had a single amenity while 1 park had more than 4 amenities. Distance from a participant's home to the nearest park ranged from less than 0.1 to 8.8 miles (mean [standard deviation], 1.2 [1.8]). CONCLUSION: These 12 Lower Mississippi Delta towns scored low on assessments of physical environment features and amenities, town characteristics, and programs and policies associated with physical activity in rural communities. To increase the physical activity levels of rural residents, it may be necessary to first improve the built environment in which they live.

INTRODUCTION: Although modifications to dietary and physical activity (PA) behavior can reduce blood pressure, racial disparities in prevalence and control of hypertension persist. Psychosocial constructs (PSCs) of self-regulation, processes of change, and social support are associated with initiation and maintenance of PA in African Americans; which PSCs best predict lifestyle behavior changes is unclear. This study's objective was to examine relationships among PSC changes and postintervention changes in PA and dietary outcomes in a community-based, multicomponent lifestyle intervention. METHODS: This study was a noncontrolled, pre/post experimental intervention conducted in a midsized, Southern US city in 2010. Primarily African American adults (n = 269) participated in a 6-month intervention consisting of motivational enhancement, social support, pedometer diary self-monitoring, and 5 education sessions. Outcome measures included pedometer-determined steps per day, fitness, dietary intake, and PSC measures. Generalized linear mixed models were used to test for postintervention changes in behavioral outcomes, identify predictors of PSC changes, and determine if PSC changes predicted changes in PA and diet. RESULTS: Postintervention changes were apparent for 10 of 24 PSCs (P < .05). Processes of change components, including helping relationships, reinforcement management, and consciousness raising, were significant predictors of fitness change (P < .05). CONCLUSION: This article is among the first to address how measures of several theoretical frameworks of behavior change influence changes in PA and dietary outcomes in a multicomponent, community-based, lifestyle intervention conducted with African American adults. Findings reported identify PSC factors on which health behavior interventions can focus.

RESUMEN
INTRODUCTION: Effective strategies are needed to reach and treat people who lack awareness of or have uncontrolled hypertension. We used data from a community-based participatory research initiative, Hub City Steps, to quantify the prevalence of undiagnosed hypertension and determine the relationship between hypertension status at baseline and postintervention improvements in blood pressure and health-related quality of life. METHODS: Hub City Steps was a 6-month preintervention-postintervention lifestyle intervention targeting hypertension risk factors. Outcome measures were collected at baseline, 3 months, and 6 months. Generalized linear mixed models were used to test for effects by time and hypertension status. RESULTS: Of the enrolled sample (N = 269), most were overweight or obese (91%), African American (94%), and women (85%). When considering hypertension status, 42% had self-reported diagnosis of hypertension (self-reported subgroup; 84% with antihypertensive medication use); 36% had no self-reported medical history of hypertension, but when blood pressure was measured they had a clinical diagnosis of prehypertension or hypertension (undiagnosed subgroup); and 22% had no self-reported or clinical hypertension diagnosis (no hypertension subgroup). From baseline to 6 months, systolic blood pressure significantly improved for participants with self-reported hypertension [8.2 (SD, 18.2) mm Hg] and undiagnosed hypertension [12.3 (SD, 16.3) mm Hg], with undiagnosed participants experiencing the greatest improvements (P < .001). Effects remained significant after controlling for covariates. Health-related quality of life significantly improved for all 3 hypertension subgroups, with no apparent subgroup differences. CONCLUSION: This study reveals advantages of a culturally appropriate community-based participatory research initiative to reach those with undetected hypertension and effectively improve blood pressure status and health-related quality of life.

Background: Links between diet and food security are well established, but less is known about how food and nutrition security affect a household's ability to decide what to consume. Objectives: This study's purpose was to quantify and compare causal pathways from 1) food and nutrition security to perceived dietary choice and 2) food and nutrition security to perceived healthfulness of food choice while testing for mediation by perceived limited availability of foods and utilization barriers to healthful meals. Methods: Causal mediation analysis was conducted using an observational data set. Exposures included food insecurity and nutrition insecurity; mediators included perceived limited availability and utilization barriers; outcomes included perceived dietary choice and healthfulness choice; covariates included income and education. Results: Dietary choice (range 0-4) was 0.9 to 1.1 points lower for participants with food/nutrition insecurity compared with participants with food/nutrition security (direct effects). Neither mediation nor moderation by perceived limited availability were present. Seventeen percent and 11 %, respectively, of the effects of food and nutrition security on dietary choice could be contributed to utilization barriers (mediation). Moderation by utilization barriers was present only for nutrition security (differences in dietary choice only present when barriers were low). Healthfulness choice (range 0-4) was 0.6 to 0.7 points lower for participants with food/nutrition insecurity compared with participants with food/nutrition security (direct effects). Mediation by perceived limited availability and utilization barriers was not present. Moderation was present only for nutrition security (differences in healthfulness choice only present when perceived limited availability was low; differences in healthfulness choice only present when barriers were low). Conclusions: Food and nutrition security affect food choices, with utilization barriers acting as an intermediary step. When environmental and household utilization barriers to healthful food purchasing and preparation are high, the ability to decide what to consume does not differ between households with nutrition security and those with nutrition insecurity.
RESUMEN
PURPOSE: To estimate the percentage of United States adults who accurately assessed their diet quality (DQ). DESIGN: Observational, cross-sectional, nationally representative. SETTING: National Health and Nutrition Examination Survey, 2015-2018. SAMPLE: 9757 (86%) of 11 288 adults aged ≥20 years. MEASURES: Perceived DQ was assessed by asking participants, how healthy is your diet? The five responses included excellent, very good, good, fair, and poor. Measured DQ was assessed using 24-hours dietary recalls scored with 2015 Healthy Eating Index; scores were categorized using a 10-point grading scale. ANALYSIS: Matches between perceived and measured DQ that were classified as accurate included: excellent = A, very good = A or B, good = B or C, fair = C or D, and poor = D or F. All others were classified as inaccurate. Analyses included descriptive statistics and multivariable logistic regression for complex survey designs. RESULTS: 63% of adults perceived their DQ as very good or good while 70% scored DQ grades of F. Overall, 15% of adults accurately assessed their DQ with 96% accuracy in the poor perception group and <23% in the other 4 groups. Overall, 75% of adults overrated their DQ. Females, adults with lower educational attainment, and those with low food security were more likely to accurately assess their DQ. CONCLUSION: Adults cannot accurately assess their DQ except for those perceiving their DQ as poor, and the majority overrate their DQ.

The study's purpose was to determine small farm product amounts and seasonality and examine spatial relationships between small farms and K-12 public schools in Mississippi. Online survey participation invitations were sent via email to farmers and school food service directors from October 2021 to January 2022. Data were summarized using descriptive statistics and proximities between farms (n = 29) and schools (n = 122) determined using spatial analysis. Median yearly amounts for both fresh fruits and vegetables ranged from 1-50 to 201-500 pounds while other product amounts ranged from 1-50 to >1000 pounds. Fresh fruits, fresh vegetables, and other product seasonality ranged from 1 to 6 months, 1 to 12 months, and 3 to 12 months, respectively. In total, 8 out of 12 fresh fruits, 24 out of 25 fresh vegetables, and all other products were harvested during the academic school year. Fifty percent of the schools were within a 20-mile radius of at least one small farm, while 98% were within a 50-mile radius. While many product amounts were small (1-50 pounds), most were harvested during the school year and in close proximity to at least one school. Contracting directly with farmers may be more attractive to school food authorities given current supply chain disruptions and decreasing product availability for school meal programs.

BACKGROUND: Walking for exercise remains the most frequently reported leisure-time activity, likely because it is simple, inexpensive, and easily incorporated into most people's lifestyle. Pedometers are simple, convenient, and economical tools that can be used to quantify step-determined physical activity. Few studies have attempted to define the direct relationship between dynamic changes in pedometer-determined steps/day and changes in anthropometric and clinical outcomes. Hence, the objective of this secondary analysis was to evaluate the utility of several descriptive indicators of pedometer-determined steps/day for predicting changes in anthropometric and clinical outcomes using data from a community-based walking intervention, HUB City Steps, conducted in a southern, African American population. A secondary aim was to evaluate whether treating steps/day data for implausible values affected the ability of these data to predict intervention-induced changes in clinical and anthropometric outcomes. METHODS: The data used in this secondary analysis were collected in 2010 from 269 participants in a six-month walking intervention targeting a reduction in blood pressure. Throughout the intervention, participants submitted weekly steps/day diaries based on pedometer self-monitoring. Changes (six-month minus baseline) in anthropometric (body mass index, waist circumference, percent body fat [%BF], fat mass) and clinical (blood pressure, lipids, glucose) outcomes were evaluated. Associations between steps/day indicators and changes in anthropometric and clinical outcomes were assessed using bivariate tests and multivariable linear regression analysis which controlled for demographic and baseline covariates. RESULTS: Significant negative bivariate associations were observed between steps/day indicators and the majority of anthropometric and clinical outcome changes (r = -0.3 to -0.2: P < 0.05). After controlling for covariates in the regression analysis, only the relationships between steps/day indicators and changes in anthropometric (not clinical) outcomes remained significant. For example, a 1,000 steps/day increase in intervention mean steps/day resulted in a 0.1% decrease in %BF. Results for the three pedometer datasets (full, truncated, and excluded) were similar and yielded few meaningful differences in interpretation of the findings. CONCLUSIONS: Several descriptive indicators of steps/day may be useful for predicting anthropometric outcome changes. Further, manipulating steps/day data to address implausible values has little overall effect on the ability to predict these anthropometric changes.

RESUMEN
Background: Little is known about the simultaneous use of screen time (ST) parenting practices in children. Hence, study objectives were to determine patterns of ST parenting practices and associations with demographic, anthropometric, and sedentary behavior measures in parents and their adolescent children (12-17 years). Methods: Dyadic survey data from Family Life, Activity, Sun, Health, and Eating, a cross-sectional, internet-based study, conducted in 2014 were analyzed using latent class analysis on six ST parenting practices-permissive, rules/limits, monitoring, modeling, accessibility, and negotiated rules. Self-report model covariates included adolescent age and parent and adolescent sex, body weight category, and sedentary behavior. Results: Based on 1200 parent-adolescent dyads, five latent classes were identified representing a continuum of practice use (high to low)-Complete Influencers (16%, reference class), Disagreeing Influencers (18%), Positive Influencers (24%), Negative Influencers (23%), and Indifferent Influencers (20%). Disagreeing, Indifferent, and Negative Influencers were 50%-81% and 45%-49% less likely to contain younger adolescent dyads and male adolescent dyads, respectively. Dyads with adolescent overweight/obesity had twice the odds of belonging to one of the other four classes. Odds of belonging to one of the other four classes were 3%-9% lower for every 1 minute/day increase in adolescent sedentary behavior. Conclusions: Parents utilize distinct patterns of ST practices, which are differentially associated with adolescent age, sex, weight, and sedentary behavior. Advocating for parental use of combinations of practices, like rules/limits and monitoring, to decrease their adolescents' ST may prove more beneficial than no practice use.

Objectives: In this study, we tested for moderation by neighborhood food outlet presence on relationships between food outlet shopping or meal sources and dietary intake. Methods: We used generalized linear models to analyze parent-adolescent (12-17 years) dyad data from the 2014 Family Life, Activity, Sun, Health and Eating. Questions included food outlet presence in home (parent) and school (adolescent) neighborhoods (yes or no), shopping at food outlets (parent) (never, rarely, sometimes, often or always), and sources of food consumed away from and at home (weekly frequency). We captured food and beverage intakes via a dietary screener. Results: Relationships between adolescent added sugar intake and scratch cooked evening meals and meals away from home were found only when grocery stores and fast food restaurants, respectively, were present in adolescents' school neighborhoods. Shopping at fruit and vegetable (FV) markets and scratch cooked evening meals were associated with the largest increases in parent and adolescent FV intakes, respectively. Meals away from home at convenience stores were associated with the largest increases in parent and adolescent intakes of added sugars. Conclusions: Neighborhood grocery store and fast food restaurant presence moderated relationships between meal sources and dietary intake only in adolescents.

OBJECTIVE: The primary objective was to use the Healthy Eating Index-2015 (HEI-2015) to describe diet quality by categories of body mass index (BMI) and by sociodemographic characteristics within categories of BMI using a nationally representative sample of US children. METHODS: Dietary datasets from three cycles of the National Health and Nutrition Examination Survey (2009-2014) were analysed for children 2 to 18 years of age (N = 8894). Using the population ratio method, mean and 95% confidence intervals for HEI-2015 total and component scores were computed by BMI (underweight, normal weight, overweight, and obese) and by age (2-5, 6-11, and 12-18 y), gender, race/ethnicity (non-Hispanic black, non-Hispanic white, Mexican American, other Hispanic, and other race), and family poverty to income ratio (below and at/above poverty threshold). RESULTS: HEI-2015 mean total scores were 50.4, 55.2, 55.1, and 54.0 out of 100 points for children with underweight, normal weight, overweight, and obesity, respectively, and were not significantly different. Within BMI categories, significant differences in total and mean component scores were present for age and race/ethnicity groups. CONCLUSIONS: Total and most components of diet quality did not significantly differ among child populations classified by BMI status. Within BMI categories, significant diet quality differences were found for age and race/ethnicity groups, although scores were low for all child groups. Researchers may need to address or target specific dietary components with low quality in various child populations to have the greatest effect on improving nutrition nationwide.
RESUMEN
Background: The study's objective was to determine patterns of food parenting practices regarding fruit and vegetables (FV) and their associations with demographic characteristics and dietary intake in parents and adolescents (12-17 years). Methods: Dyadic survey data from Family Life, Activity, Sun, Health, and Eating, a cross-sectional, Internet-based study, conducted in 2014 were analyzed using latent class analysis. Self-report model covariates included adolescent age and parent and adolescent sex, BMI, FV intake, and FV legitimacy of parental authority (FV-LPA). Results: Based on 1657 parent-adolescent dyads, 5 latent classes were identified representing use of all 6 to use of few FV parenting practices. Parent and adolescent responses agreed in four classes. The high use class was the reference class. Compared with early adolescent dyads, middle adolescent dyads had 58% and 66% lower odds of belonging to moderate and low use classes. Compared with female parent dyads, male parent dyads had over three times greater odds of belonging to low use class. Compared with female adolescent dyads, male adolescent dyads had 44% lower odds of belonging to disagreeing class. The odds of belonging to one of the other four classes were 19%-63% lower for every one cup equivalent increase in parent FV intake. Compared with dyads with high parental or adolescent agreement with FV-LPA, dyads with low agreement had 2.5-7 times the odds of belonging to another class. Conclusions: Distinct patterns of FV parenting practices exist and are associated with parent and adolescent demographic characteristics, dietary intake, and FV-LPA.
