Variation in Adolescent Fruit Consumption Perception: a randomized controlled community trial in Duque de Caxias – RJ

Resumo Introdução A autoavaliação do consumo é um dos fatores determinantes para adoção de uma alimentação adequada e saudável. Objetivo Avaliar o efeito de uma intervenção nutricional na percepção do consumo de frutas em adolescentes. Método Trata-se de um ensaio comunitário randomizado controlado de base escolar. A intervenção consistiu em ações integradas de prevenção primária (nas escolas) e secundária (nos domicílios). Os participantes foram classificados em otimistas e não otimistas em relação à percepção do consumo de frutas combinando duas variáveis: frequência de consumo e autoavaliação da quantidade consumida. O efeito da intervenção foi testado por modelo de regressão logística com efeitos aleatórios. Resultados A frequência de otimistas na linha de base foi 19,1% e 18,5% nos grupos controle e intervenção, e 17,5% e 17,6% pós-intervenção, respectivamente (p=0,743 para interação grupo*tempo, e p=0,802 no modelo ajustado pela cor da pele). A prevalência de otimistas foi maior entre os meninos, entre aqueles que avaliaram sua alimentação como excelente/muito boa, com menor frequência de consumo de refrigerante e de biscoito, e entre aqueles que relataram realizar café da manhã ou almoço com os pais nunca ou quase nunca. Conclusão Não houve efeito da intervenção na mudança de percepção quanto ao consumo de frutas.

THE RELATIONSHIP BETWEEN SOCIAL ECONOMY AND PEER SUPPORT WITH VEGETABLES AND FRUIT CONSUMPTION BEHAVIORS AMONG VOCATIONAL STUDENT

Adolescent generally undergo changes in their lifestyle, including their consumption pattern.. Consumption of vegetables and fruit in adolescents is very important to support growth and good health status, if teenagers consume less vegetables and fruits are at risk of experiencing degenerative diseases that usually appear in adulthood. One of the problems in the juvenile phase is the lack of consumption of vegetables and fruits which are influenced by internal and external factors. Several factors related to the adequacy of vegetable and fruit consumption in adolescents include: characteristics, socioeconomic, and social support (family and peers). The research problem is how is the socio-economic relationship with the consumption of vegetables and fruits. The aim of the study was to examine socio-economic relations with consumption of vegetables and fruit students. This research is quantitative using a cross-sectional research design. The study was conducted at the State Vocational School 1 Percut Sei Tuan in Deli Serdang District. The samples were all students of class X and class XI Department of Software Engineering State Vocational High School 1 Percut Sei Tuan Deli Serdang Regency in 2018 amounting to 97 people. Data collection tool uses a questionnaire. The test used is chi-square (bivariate). The chi-square test results show that there is no a relationship between socioeconomic with vegetable consumption (p>0.05), whereas peer support there is relationship with vegetable consumption (p<0.05) and there is a relationship between socioeconomic (income household permonth, pocket money, vegetable available) and peer support with fruit consumptio (p<0.05). Researchers suggest that families, especially parents, continue to control adolescents, including peers and in terms of consumption of vegetable and fruit both at home and outside the home.

Faktor – Faktor Yang Berhubungan Dengan Konsumsi Buah-Sayur Pada Remaja Di Daerah Rural-Urban, Yogyakarta

Vegetable consumption of the Indonesian population is still low in the teen age group both in rural and urban areas. Consumption of fruits and vegetables in adolescents is important for preventing degenerative diseases. The aim of the study was to determine the factors associated with fruit and vegetable consumption in adolescents in rural-urban areas. This study used a cross-sectional research design in Yogyakarta with 196 rural-urban teens. The analysis used was univariate, bivariate, analysis. The results showed that teenagers in urban areas ate less vegetables. Whereas in teenagers in rural areas, they consume less fruit. There is a significant relationship between vegetable consumption in adolescents in rural areas with father's education level (p = 0.031) and self-image perception (p = 0.041), while in urban areas there is a significant relationship between vegetable consumption and self-image perception (p = 0.049) and education in adolescents (p = 0.047). Fruit consumption in adolescents in rural areas that are significantly related is the perception of body image (p = 0.016), while in adolescents in urban areas that are significantly related is monthly money (p = 0.003). Suggestions that can be given are provide health education about the importance of the benefits of vegetables and fruit. 

Reliability and Validity of the Turkish Version of the Situational Self-Efficacy Scale for Fruit and Vegetable Consumption in Adolescents

The purpose of this research was to examine the psychometric properties of the Turkish version of the situational self-efficacy scale for vegetable and fruit consumption in adolescents. This was a methodological study. The study was conducted in four public secondary schools in Istanbul, Turkey. Subjects were 1586 adolescents. Content and construct validity were assessed to test the validity of the scale. The reliability was assessed in terms of internal consistency and test-retest reliability. For confirmatory factor analysis, χ(2) statistics plus other fit indices were used, including the goodness-of-fit index, the adjusted goodness-of-fit index, the nonnormed fit index, the comparative fit index, the standardized root mean residual, and the root mean square error of approximation. Pearson's correlation was used for test-retest reliability and item total correlation. The internal consistency was assessed by using Cronbach α. Confirmatory factor analysis strongly supported the three-component structure representing positive social situations (α = .81), negative effect situations (α = .93), and difficult situations (α = .78). Psychometric analyses of the Turkish version of the situational self-efficacy scale indicate high reliability and good content and construct validity. Researchers and health professionals will find it useful to employ the Turkish situational self-efficacy scale in evaluating situational self-efficacy for fruit and vegetable consumption in Turkish adolescents.

Impact of Fruit Smoothies on Adolescent Fruit Consumption at School.

We examine the impact of serving fruit smoothies during school breakfast on fruit consumption among middle school and high school students. We draw on observational plate-waste data over a 10-week period during which fruit smoothies were introduced for breakfast at two Utah schools. Our total sample includes 2,760 student-day observations. We find that the fraction of students eating a full serving of whole fruit increased from 4.3% to 45.1%. As such, school districts should consider offering fruit smoothies as part of a set of interventions designed to increase fruit consumption at school.

Don't tell me what I should do, but what others do: The influence of descriptive and injunctive peer norms on fruit consumption in adolescents

While healthy eating patterns are of high importance in adolescence, most adolescents portray quite unhealthy eating behaviour. One reason for this may be that social norms among peers tend to be unsupportive of healthy eating. The current study investigates whether communicating health-promoting descriptive and injunctive norms influences adolescents' intended and actual fruit consumption. The study employed an experimental prospective design. A norm message manipulation (descriptive vs. injunctive vs. no-norm control) was administered to high school students, after which fruit intake intention (N = 96) was assessed. At follow-up, actual fruit intake over 2 days (N = 80) was recorded. Adolescents receiving the descriptive norm did not report higher fruit intake intentions than the control group, but did consume (borderline, p = .057) significantly more fruit in the following 2 days (2.3 portions per day) than the control condition (1.7 portion per day). Adolescents receiving the injunctive norm reported lower fruit intake intentions than the other two groups, but actual fruit consumption (1.5 portions per day) was similar to that of the control group. Health-promoting injunctive norms not only had no positive effects on fruit intake but actually caused a decrease in fruit intake intentions, indicating that injunctive norms may be vulnerable to reactance. A health-promoting descriptive norm was found to positively affect fruit intake in adolescents. No effect on fruit intake intention was found. Results show that simple single-sentence norm messages hold the potential to substantially influence health behaviour.

Parental influences on adolescent fruit consumption: the role of adolescent self-efficacy

The aims of this study were to examine whether adolescent self-efficacy mediates the associations between parental control, perceptions of the importance of healthy nutrition for child health and barriers to buying fruits and vegetables and adolescent fruit consumption using a theoretically derived explanatory model. Data were drawn from a community-based sample of 1606 adolescents in Years 7 and 9 of secondary school and their parents, from Victoria, Australia. Adolescents completed a web-based survey assessing their fruit consumption and self-efficacy for increasing fruit consumption. Parents completed a survey delivered via mail assessing parental control, perceptions and barriers to buying fruit and vegetables. Adolescent self-efficacy for increasing fruit consumption mediated the positive associations between parental control and perceptions of the importance of healthy nutrition for child health and adolescent fruit consumption. Furthermore, adolescent self-efficacy mediated the negative association between parental barriers to buying fruits and vegetables and adolescent fruit consumption. The importance of explicating the mechanisms through which parental factors influence adolescent fruit consumption not only relates to the advancement of scientific knowledge but also offers potential avenues for intervention. Future research should assess the effectiveness of methods to increase adolescent fruit consumption by focussing on both improving adolescents' dietary self-efficacy and on targeting parental control, perceptions and barriers.

Family correlates of fruit and vegetable consumption in children and adolescents: a systematic review

To review associations between the family environment and young people's fruit and vegetable consumption. A systematic review. Published English-language (n 60) papers were identified using electronic databases and manual searches of personal files and reference lists. Observational research reporting a measure of fruit/vegetable intake for children (aged 6-11 years) and/or adolescents (aged 12-18 years) and at least one potential family correlate of dietary intake was included. Parental modelling and parental intake were consistently and positively associated with children's fruit and fruit, juice and vegetable (FJV) consumption. There were also positive associations between home availability, family rules and parental encouragement and children's fruit and vegetable consumption. Parental intake was positively associated with adolescents' fruit and vegetable consumption. There were also positive associations between parental occupational status and adolescent fruit consumption and between parental education and adolescents' FJV consumption. Our findings highlight the importance of targeting the family environment for the promotion of healthy eating behaviours among children and adolescents. Future interventions should encourage parents to be positive role models by targeting parental intake and to create a supportive home environment through increased encouragement and availability of fruits and vegetables and employing rules to govern eating behaviours. For adolescents, indicators of family circumstances (e.g. parental education) should be used to identify target groups for interventions aimed at promoting healthy eating.

Parenting style and adolescent fruit consumption

The importance of the social environment for dietary behaviour has been highlighted in the past decade. A type of environmental influence that has received increasing research attention in recent years is the influence that parents can have on their children's dietary behaviour through food-related parenting practices. Much of the work done so far, however, has reported inconsistent findings and poorly understood mechanisms of influence. The present study aimed to explore the possible environmental influence of general parenting style on adolescent food choice patterns. Data were collected at schools ( N=643; mean age 16.5 years), using self-administered questionnaires on parenting style, fruit intake behaviour and fruit-specific cognitions. Consistent and theoretically predictable differences were found between adolescents who described their parents as authoritative, authoritarian, indulgent or neglectful. Fruit consumption and fruit-specific cognitions were most favourable among adolescents who were being raised with an authoritative parenting style. Children of parents with indulgent parenting styles consumed more fruit than adolescents from authoritarian or neglectful homes. Consequences of these results for the interpretation of earlier studies on the influence of parenting practices are discussed, and a research model is proposed for future studies of parental influences on adolescent dietary behaviours.
