Background and Objectives: Childhood obesity and being overweight are influenced by the family environment, diet, sleep, and mental health, with parents playing a key role in shaping behaviors through routines and practices. Healthy parental habits can encourage positive outcomes, while poor routines and stress often lead to unhealthy weight gain. This study analyzed the impact of parental behaviors on children’s lifestyles and habits, as well as the trend and intensity of the effect of these behaviors on different age groups. Methods: A systematic review of 1504 articles from Web of Science, PubMed, Scopus, and APA PsycNet (as of 22 July 2024) included studies on parents and children aged 4–18 years, focusing on physical activity, sleep, screen time, nutrition, and mental health. Twenty-six studies were analyzed, including 19 cross-sectional and 7 longitudinal studies. The outcomes included physical activity, sedentary behaviors, eating and sleeping habits, mental health, and BMI. Bias was assessed using JBI tools according to the GRADE framework and Newcastle-Ottawa Quality Assessment. Results: The studies involved 89,545 youths and 13,856 parents. The key findings revealed associations between parental physical activity, sleep, dietary habits, mental health, screen time, and their children’s BMIs. Parenting styles significantly influence children’s behaviors. This review highlights the crucial influence of parenting styles and behaviors on children’s physical activity, diet, sleep, and mental health, emphasizing the link between family dynamics and childhood obesity. The findings stress the importance of targeting parental habits in interventions focused on healthy routines and stress management. Longitudinal studies are needed to determine causality, while research involving diverse populations is essential to enhance the applicability of these findings.

This article presents a set of research studies that aim to adapt Carol Ryff‘s scales of psychological well-being (SPWB) and to analyze its psychometric properties in adolescents. The first two studies focused on the reliability and factorial validity of different Portuguese short versions of SPWB, revealing measurement models inadequacies and low internal consistency. In the third study we developed a shortened version (30 items), taking into account the application of psychometric criteria suggested by van Dierendonck (2005). The scales of this version revealed better reliability and adequate goodness of fit indices for the six-factor model, as proposed by Carol Ryff’s PWB theory. Although further research focused on the psychometrical properties reanalysis of this shortened version of SPWB is needed, this article provides a contribution to the research and intervention on positive mental health during adolescence.
