Association between Fathers' and Mothers' Parenting Styles and the Risk of Overweight/Obesity among Adolescents in San José Province, Costa Rica.

Parenting styles are a risk factor for adolescents overweight/obesity worldwide, but this association is not well understood in the context of Latin America. This study examines the association between the parenting styles of mothers and fathers and the risk of overweight/obesity among Costa Rican adolescents. Data are cross-sectional from a sample of adolescents (13-18 years old) enrolled in ten urban and eight rural schools (n = 18) in the province of San José, Costa Rica, in 2017. Hierarchical logistic regression analyses were performed to assess the likelihood of adolescents being overweight according to the mothers' and fathers' parenting styles. A significant association was found between the risk of adolescent overweight/obesity and the paternal authoritarian style only in rural areas (B = 0.622, SE = 0.317, Wald = 3.864, ExpB = 1.863, p = 0.04), and between said risk and the paternal permissive style only in male adolescents (B = 0.901, SE = 0.435, Wald = 4.286, ExpB = 2.461, p = 0.038). For maternal parenting styles, no associations reached significant levels once logistic regression models were adjusted for the fathers' parenting styles. These findings underscore the importance of further studying the role of fathers' paternal parenting styles on Latin American adolescent weight outcomes. Expanding our understanding of the parenting styles of fathers has important implications for the design and implementation of culturally- and gender-appropriate family interventions.

Gender-based eating norms, the family environment and food intake among Costa Rican adolescents.

OBJECTIVE: To examine the association between family environment variables (parenting styles, family meal atmosphere), gender-based stereotypes and food intake in Latin American adolescents. DESIGN: Structural equation modelling applied to cross-sectional data, 2017. SETTING: Urban and rural sites of San José, Costa Rica. PARTICIPANTS: n 813; 13-18 years old. RESULTS: Data suggest direct associations between gender-based stereotypes and intake of fruits and vegetables (FV) (ß = 0·20, P < 0·05), unhealthy foods (fast food (FF)) (ß = -0·24, P < 0·01) and ultra-processed foods (ß = -0·15, P < 0·05) among urban girls; intake of legumes among rural girls (ß = 0·16, P < 0·05) and intake of sugar-sweetened beverages (SSB) among rural boys (ß = 0·22, P < 0·05). Family meal atmosphere was associated with legume intake (ß = 0·19, P <·05) among rural girls. Authoritative parenting style was associated with FV intake (ß = 0·23, P < 0·05) among urban boys and FF intake (ß = 0·17, P < 0·05) among urban girls. Authoritarian parenting style was associated with FV consumption (ß = 0·19, P < 0·05) among rural boys, and with SSB and FF consumption (ß = 0·21, P < 0·05; ß = 0·14, P < 0·05, respectively) among urban girls. CONCLUSIONS: Findings are the first to describe the complex family environment and gender-based stereotypes within the context of a Latin American country. They emphasise the need for culturally relevant measurements to characterise the sociocultural context in which parent-adolescent dyads socialise and influence food consumption.

Modelling Longitudinal Directional Associations Between Self-regulation, Physical Activity, and Habit: Results from a Cross-lagged Panel Model.

BACKGROUND: The directionality of associations between self-regulatory variables, behavior, and automaticity is seldomly tested. In this study, we aimed to examine a volitional, self-regulatory sequence of variables proposed in the Health Action Process Approach framework (intention → action plans → action control → behavior) and its relationship with the construct of automaticity of the physical activity habit. METHODS: Longitudinal data was collected from high school students (N = 203, Mage = 15.39 (SD = 1.43), 52% women) at three measurement points. First, a confirmatory factor analysis measurement model was used to examine the study variables across measurement points. Next, a cross-lagged panel model was used to test directionality between variables. RESULTS: After adequate fit of the measurement model was confirmed, a mechanism integrating self-regulation with behavior and automaticity was examined. The hypothesized directionality between variables was verified overall by cross-lagged analysis. However, for the intention-action plan association, the inverse relationship was found: plans were associated with subsequent intentions, but intentions did not predict plans. Moreover, automaticity was not associated with subsequent physical activity behavior. CONCLUSIONS: In general, our findings supported the hypothesized longitudinal direction of the associations, confirming that self-regulation may lead to behavior performance and automaticity. Unexpected findings and implications for intervention and future research are discussed.

Gender-based food intake stereotype scale (GBFISS) for adolescents: development and psychometric evaluation.

Objective. The study aimed to develop and test the validity and reliability of a gender-based food intake stereotype scale (GBFISS) to further the understanding of gender stereotype influences on food intake. Design. Two cross-sectional studies were conducted among adolescents. In the first one (n = 611), exploratory and confirmatory factor analyses were performed on subsamples to identify and cross-validate the scale's structure. Evidence of concurrent validity (correlation with sexism) was also examined. In the second study (n = 813), confirmatory factor analysis was conducted to confirm the scale's dimensionality on a different sample. Further evidence of construct validity (correlations with food intake and social desirability) was examined. Invariance was tested for different features as well. Main outcome. The Gender-Based Food Intake Stereotype Scale. Results. Factor analyses on the first and second studies helped identify and confirm the GBFISS as a three-dimensional scale. The studies also provided evidence of construct validity. Support for invariance by gender and age was found, and reliability was acceptable. Conclusion. The evidence suggests that the GBFISS is valid and reliable. Further research is recommended. The contribution of gender stereotypes, as measured by the GBFISS, to well-established health behavior models should be examined.

Re-evaluating the self-report habit index: the cases of physical activity and snacking habits.

Objectives: The Self-Report Habit Index (SRHI) was originally reported as one-dimensional; however, habit has been described as characterised by several features. Moreover, one-dimensional models for the SRHI have demonstrated poor fit. Therefore, we aimed to compare multidimensional models with a one-dimensional model in both snacking and physical activity habits, besides examining further instrument characteristics. Design: A cross-sectional study was conducted with high school and university students (n = 555). Main outcome measure: The SRHI adapted for physical activity and for snaking habits was applied at one time point. Results: Nested models with one factor, two factors and three factors were compared. Next, a hierarchical second-order model was tested, and further validity issues, as well as invariance between habits, were examined. Three-dimensional models represented a better fit for both habits. However, fit was still inadequate in the snacking version. In addition, discriminant validity concerns emerged for the physical activity SRHI. Moreover, invariance between the snacking and the physical activity versions was not confirmed. Conclusions: Considering the SRHI as composed by the dimensions of 'lack of awareness', 'lack of control' and 'history of behavioural repetition' seems to be more accurate. Nevertheless, our findings suggest that further research is needed.

Social-cognitive antecedents of hand washing: Action control bridges the planning-behaviour gap.

OBJECTIVES: To examine motivational and volitional factors for hand washing in young adults, using the Health Action Process Approach (HAPA) as a theoretical framework. DESIGN: In a longitudinal design with two measurement points, six weeks apart, university students (N = 440) completed paper-based questionnaires. MAIN OUTCOME MEASURES: Prior hand washing frequency, self-efficacy, outcome expectancies, intention and action planning were measured at baseline, and coping planning, action control and hand washing frequency were measured at follow-up. RESULTS: A theory-based structural equation model was specified. In line with the HAPA, the motivational factors of self-efficacy and outcome expectancies predicted intention, whereas the volitional factors of planning and action control mediated between intention and changes in hand washing frequency. Action control was confirmed as the most proximal factor on hand washing behaviour, thus representing a bridge of the planning-behaviour gap. CONCLUSIONS: Both motivational and volitional processes are important to consider in the improvement of hand hygiene practices. Moreover, the statistically significant effects for planning and action control illustrate the importance of these key self-regulatory factors in the prediction of hand hygiene. The current study highlights the importance of adopting models that account for motivational and volitional factors to better understand hand washing behaviour.

Effects of Self-Rated Health and Self-Rated Economic Situation on Depressed Mood Via Life Satisfaction Among Older Adults in Costa Rica.

OBJECTIVE: The study examined the relationship of self-rated health and self-rated economic situation with depressed mood, and life satisfaction as mediator of this relationship among older adults in Costa Rica. METHOD: A longitudinal study was conducted with a subsample (N = 1,618) from the Costa Rican Longevity and Healthy Aging Study (CRELES). Self-rated health, self-rated economic situation, depressed mood, and life satisfaction were measured at baseline, and depressed mood was reassessed 18 months later. Putative mechanisms for changes in depressed mood were examined by means of conditional process analysis. RESULTS: Self-rated health was negatively associated to depressed mood. This effect took place via life satisfaction. An interaction showed that better economic situation compensated the effect of a low self-rated health on life satisfaction. DISCUSSION: This study suggests that subjective variables such as self-rated health, economic situation, and life satisfaction should be considered when addressing the onset of depressed mood.

Promoting action control and coping planning to improve hand hygiene.

BACKGROUND: We examined a brief educational intervention addressing hand hygiene self-regulatory mechanisms, and evaluated which psychological mechanisms may lead to hand hygiene behaviours. METHODS: Two hundred forty two students (mean age = 21 years, SD = 3.9) received either an experimental (n = 149) or a control condition on action control and planning (n = 93). Hand hygiene, coping planning, and action control were measured at baseline and six weeks later. By applying repeated measures ANOVA, we compared the experimental condition addressing planning to perform hand hygiene with a control condition. Additionally, working mechanisms were evaluated by means of mediation analysis. RESULTS: The intervention had an effect on action control, as reflected by a time by treatment interaction. The direct effect of the intervention on behaviour was, however, non-significant. Changes in action control led to changes in coping planning. These social-cognitive changes mediated the effect of intervention on behaviour, after controlling for gender, baseline behaviour, and classroom membership. DISCUSSION: In spite of the associations between the intervention and self-regulatory strategies, no direct effect was found of the intervention on behaviour. Further research on how to increase hand sanitizing, involving enviromental characteristics, is required. CONCLUSION: The intervention led only indirectly to an improvement of hand hygiene via changes in self-regulatory factors. Results indicate the importance of promoting action control and coping planning to initiate changes in hand hygienic behaviours.

Action control bridges the planning-behaviour gap: a longitudinal study on physical exercise in young adults.

OBJECTIVES: Maintaining physical exercise levels may not only require motivation and planning but also action control which is supposed to mediate between planning and exercise. DESIGN: Behavioural intention, action planning, coping planning and past behaviour were assessed at baseline, and action control and concurrent exercise were measured one month later in 497 young adults. METHOD: Three nested structural models were specified to examine different mediation mechanisms. One model reflected the intention-planning-behaviour chain, the other one focused on the intention-action control-behaviour chain and the third model comprised the full sequence. RESULTS: Indirect effects from intentions on exercise involved either planning or action control as mediating variables. In Model 3, all three constructs (action planning, coping planning and action control) were sequential mediators between intentions and later physical exercise levels. Action and coping planning were not directly but indirectly related to exercise via action control. CONCLUSIONS: Findings support the sequential mediation for planning and action control as antecedents of physical exercise. Action control is needed for exercise, because planning in itself is not always sufficient. Maintaining exercise levels may be attributed to effective self-regulatory strategies such as action control in combination with planning.

Synergistic effects of social support and self-efficacy on dietary motivation predicting fruit and vegetable intake.

BACKGROUND: Self-efficacy and social support are considered relevant predictors of fruit and vegetable intake. This study examines whether the effect of self-efficacy on fruit and vegetable intake is mediated by intention and whether this motivational process is moderated by received dietary social support. METHODS: A longitudinal study with two measurement points in time, four weeks apart, on fruit and vegetable intake was carried out with 473 students aged 19 years on average (52% women). In a conditional process analysis, dietary intention was specified as a mediator between self-efficacy and fruit and vegetable intake, whereas received dietary support was specified as a moderator of the self-efficacy-intention association, controlling for baseline fruit and vegetable intake. RESULTS: Self-efficacy was positively associated with fruit and vegetable intake four weeks later, and intention mediated this process. Moreover, an interaction between received dietary support and self-efficacy on intention emerged. CONCLUSIONS: The effect of self-efficacy on fruit and vegetable intake was fully mediated by intention. Moreover, received support exhibited a moderating role within the motivational process: high dietary support appeared to accentuate the positive relationship between self-efficacy and dietary intention.

Self-efficacy, action control, and social support explain physical activity changes among Costa Rican older adults.

BACKGROUND: Self-efficacy, action control, and social support are considered to influence changes in physical activity levels in older adults. This study examines the relationship among these variables and explores the putative mediating and moderating mechanisms that might account for activity changes. METHODS: A longitudinal study with 54 older adults (≥ 50 years of age) was carried out in Costa Rica. In a moderated mediation analysis, action control was specified as a mediator between self-efficacy and physical activity, whereas social support was specified as a moderator between self-efficacy and action control. Baseline physical activity, age, and sex were specified as covariates. RESULTS: Action control mediated between self-efficacy and physical activity. An interaction between social support and self-efficacy on action control pointed to a synergistic effect at the first stage of the mediating process. CONCLUSIONS: The effect of self-efficacy on physical activity was partly explained by action control, providing evidence of action control as a proximal mediator of physical activity. Moreover, the moderator role of social support was confirmed: high social support appeared to compensate for low levels of self-efficacy.
