Relationship of parental health-related behaviours and physical fitness in girls and boys

Associations between Dietary Patterns and Physical Activity with Physical Fitness among Adolescents in Shandong Province, China: A Cross-Sectional Study

Background: The trend of physical fitness (PF) and physical activity (PA) among Chinese adolescents is not optimistic, and unhealthy dietary behaviors are common. PA and dietary patterns (DPs) have been linked to PF in adolescents, but the associations between DPs and PF with PF in Chinese adolescents are rarely discussed. Methods: A total of 8796 adolescents aged 11–18 were enrolled from Shandong Province, China. The CNSPFS battery was applied to assess PF. PA levels and diet quality were determined using the Physical Activity Questionnaire for Adolescents and the modified Chinese Diet Quality Questionnaire, respectively. This study used factor analysis to identify DPs and linear regression models to investigate the association between PF and related factors. Results: The average PF score of the participants was 75.67. Adolescents who were girls, lived in rural areas and were active in PA performed better on the PF test (p < 0.05). Boys whose fathers were university educated or above had a higher probability of achieving higher PF scores (OR 4.36, 95% CI 1.32–14.36); however, if their mothers were university educated or above, they had a lower probability of achieving higher PF scores (OR 0.22, 95% CI 0.063–0.76). Unhealthy dietary pattern was negatively correlated with cardiorespiratory fitness in boys (OR 0.56, 95% CI 0.31–0.98). The association between unhealthy dietary pattern and girls’ BMI became significant after adjustment for PA (p < 0.05). Conclusions: Girls performed better in PF than boys. Highly educated fathers could contribute to improve the PF performance in boys. There were four DPs among adolescents in Shandong Province, and different DPs may have different effects on PF in boys and girls.

Association of low physical activity with higher respiratory tract infections frequency among pre-school children

BACKGROUND

There is no consensus on the benefits of physical activity (PA) regarding upper respiratory tract infections (URTIs) among children. This study aimed to determine an association between the PA level and URTIs in preschoolers.

METHODS

In 4-7-year-old participants, URTI symptoms were monitored using the Polish version of the Wisconsin Upper Respiratory System Survey for Kids. The daily number of steps, PA intensity, and sleep duration were measured with a Garmin-vivofit pedometer. The lag effect between the initial level of daily PA and the frequency of infections was evaluated.

RESULTS

The average daily step count from healthy days was a significant determinant of the total number of days with the URTI symptoms, and it accounted for 44% (p < 0.001) of this variable variance. A low level of baseline PA (initial 14-day "run-in" observation period) was associated with an increased risk of URTI. In the non-sport group, the severity of the URTI symptoms depended on the number of daily steps. No significant correlation was found between sleep duration and the number of URTI days.

CONCLUSION

Low levels of PA in preschoolers result in increased susceptibility to respiratory infections. Parents should encourage children to engage in PA to prevent URTIs.

IMPACT

In pre-school children, higher physical activity (PA) is associated with fewer days of upper respiratory tract infection symptoms (URTIS). Children with a higher average daily step count have fewer days with URTIS over a long-term observation period. A change in the average number of steps per day by 1000 changed the number of days with symptoms of URTI by 4 days. The severity of URTIS was inversely related to the degree of PA. Children who participate in sports 3 or more hours per week have fewer URTIS than those who do not engage in sports regularly.

Relationship between both cardiorespiratory and muscular fitness and health-related quality of life in children and adolescents: a systematic review and meta-analysis of observational studies

Background

No review to date has evaluated the association between physical fitness and health-related quality of life (HRQoL) in healthy children and adolescents. The aims of this systematic review and meta-analysis were to examine the relationship between both cardiorespiratory fitness (CRF) and muscular fitness (MF) and HRQoL in healthy subjects under 18 years of age and to describe the dimensions of HRQoL in which these relationships are more robust.

Methods

The Medline, Embase, Cochrane Library, SCIELO, SPORTDiscus and PEDro databases were systematically searched to collect observational studies that examined the relationship between CRF and HRQoL and between MF and HRQoL in participants under 18 years of age without any diagnosed medical condition. Pooled effect sizes (ES) were estimated for the associations between both CRF and MF and the various HRQoL dimensions.

Results

The pooled ES (95% CI) estimates for the relationship between CRF and HRQoL were as follows: 0.19 (0.10 to 0.27) for physical well-being, 0.19 (0.07 to 0.32) for psychological well-being, 0.20 (− 0.14 to 0.55) for perceived health status, 0.10 (0.00 to 0.20) for self-perception/self-esteem, 0.07 (− 0.05 to 0.19) for quality of family relationship, 0.14 (0.04 to 0.25) for quality of peer relationship, 0.17 (0.04 to 0.29) for everyday functioning at school and 0.20 (0.12 to 0.28) for total HRQoL score. The pooled ES (95% CI) estimates for the relationship between MF and HRQoL were: 0.25 (0.12 to 0.37) for physical well-being, 0.11 (0.04 to 0.17) for psychological well-being, 0.08 (0.01 to 0.15) for quality of family relationship, 0.14 (0.03 to 0.25) for quality of peer relationship, and 0.09 (0.03 to 0.14) for total HRQoL score.

Conclusions

Our data suggest that both CRF and MF are positively associated with HRQoL, mainly in physical, psychological and peer relationships. Moreover, CRF is positively associated with school dimensions and MF is positively associated with family relationships.

Parental Self-Efficacy as a Predictor of Children's Nutrition and the Potential Mediator Effect between the Health Promotion Program "Join the Healthy Boat" and Children's Nutrition

Overweight and obesity, as well as their associated risk factors for diseases, are already prevalent in childhood and, therefore, promoting healthy eating is important. Parental self-efficacy (PSE) and early health-promotion can be helpful in promoting healthy eating. The aim of this study was to examine the influence of PSE on children's nutrition behavior and identify PSE as a mediator between an intervention and children's nutrition. The kindergarten-based health-promotion program "Join the Healthy Boat" was evaluated in a randomized controlled trial with 558 children (4.7 ± 0.6 years; 52.3% male) participating at both times. Linear and logistic regressions as well as mediation analyses with potential covariates such as parental outcome expectancies or parental nutrition were carried out using questionnaire data. In children, PSE was positively associated with fruit and vegetable intake (β = 0.237; p < 0.001) and showed a protective effect on soft drink consumption (OR 0.728; p = 0.002). Parental nutrition was a stronger predictor of children's intake of fruit, vegetables (β = 0.451; p < 0.001), and soft drinks (OR 7.188; p < 0.001). There was no mediator effect of PSE. However, outcome expectancies were associated with PSE (β = 0.169; p = 0.032). In conclusion, interventions should promote self-efficacy, outcome expectancies, and healthy nutrition for parents as well in order to strengthen the healthy eating habits of children.

Estimated physical fitness and sociability: an interdisciplinary pilot study among French students

BACKGROUND

The aim of this pilot study is to explore the main social factors influencing estimated physical fitness.

METHODS

During the academic year of 2014/2015, 909 students from two French universities of the Hauts-de-France region completed a study including standardized anonymous self-reported questionnaires. Data were related to age, sex, social class, physical activity, social life and sociability. Physical fitness estimation was assessed through a validated VO<inf>2max</inf> questionnaire.

RESULTS

A total of 749 17- to 24-year-old students were included. The mean age was 19.58. The sample was composed mainly of girls (59.68%). The mean estimated VO<inf>2max</inf> was 39.30±2.29 for males and 32.79±2.56 for girls. Some significant dependence and risk factors were found between estimated PF and some sociocultural aspects.

CONCLUSIONS

Our study shows the importance of the socialization environment. The role, the age and the employment status of the parents are significant as they are a reference for the practice of sports and physical activities. The level of independence and sociability is strongly correlated to estimated physical fitness. These findings stress the need to develop a more holistic study, based on comprehensive and interdisciplinary approaches.

Sports activities in preschool children differed between those born to immigrants and native Italians

AIM

Despite the health benefits of physical activity in early childhood, little is known about sports practices in preschool children with different ethnic origins. The aim of this study was to investigate the sport activity patterns in native and immigrant children in northern Italy. The influence of some child and family determinants on the child's practice of club-organised sport was analysed to plan interventions.

METHODS

The study group comprised 2682 preschool children (49.5% girls) aged 5.9 ± 0.3, 2396 fathers and 2478 mothers. All the children had their height and weight measured and their parents completed a self-administered questionnaire on their child's sports participation and family characteristics.

RESULTS

Sports activities were significantly more frequent in native Italian girls than in native Italian boys and immigrant girls. Multiple linear regression analysis showed that the weekly amount of club-organised sport in preschool children was related to the sex and migrant status in the whole sample, to paternal educational level and occupation in the native-born sample and to paternal body mass index, offspring and paternal occupation in the immigrant group.

CONCLUSION

This study highlighted the need to develop specific interventions for native and immigrant preschool children to promote a healthy lifestyle.
