Dietary Patterns, Weight Perception and Obesity Status, among 10-12-Year-Old Children; an Epidemiological Study in Greece

Knowledge, attitudes, and practices related to dietary salt among older adults in Abha, Saudi Arabia

The need to foster successful aging has intensified with the aging of the global population. This study aimed to assess the knowledge, attitudes, and practices (KAP) concerning dietary salt consumption and to investigate the correlations between sociodemographic variables and salt-related KAP. A structured interview was administered to a cohort of 200 older adults in Abha City, Saudi Arabia, recruited through a convenience sampling approach. The evaluation of salt-related KAP revealed widespread low knowledge (91.5%) as participants scored less than 3, negative attitudes (85.5%) scored less than 12, and predominantly unsatisfactory practices (69.5%) with scores less than 26. Noteworthy differences emerged between participants with poor overall KAP (81.5%) and those with good KAP (18.5%). Significantly weak negative correlations were found between age (r=-0.212), marital status (-0.236), and body mass index (-0.243) with overall KAP. Further examination revealed a significantly weak positive correlation between attitude and practice (r = 0.141). KAP scores show a highly significant positive correlation with overall KAP scores (r = 0.169, 0.352, 0.969). The uncovered correlations contribute to a valuable understanding of the complex dynamics surrounding salt-related KAP. This understanding guides the design of targeted interventions, such as health education programs, promoting successful aging and public health outcomes.

Sociodemographic factors associated with weight perception of adolescents: A systematic review and meta-analysis

PURPOSE

To systematically assess the main sociodemographic factors associated with weight perception of adolescents.

METHODOLOGY

All studies related to adolescents' weight perception were retrieved from seven databases from January 2001 to July 2022. A total of 13 Medical Subject Headings (MeSH) and keywords were used to identify qualified studies, and reference lists included in the retrieved studies were manually searched to identify potentially relevant publications. Two evaluators independently assessed the eligibility and extracted data of each study. Agency for Healthcare Research and Quality (AHRQ) risk of bias evaluation tool was used to evaluate the quality and bias risk of included studies. RevMan (version: 5.3) software was used to conduct heterogeneity test and meta-analysis.

RESULTS

A total of 12 studies, published between 2003 and 2020, were selected and included in the systematic review and meta-analysis, consisting of 325,367 adolescents from five countries. The risk of bias evaluation indicated that risk of bias was low in five studies and moderate in seven studies. The results of meta-analysis showed that there were no differences in the weight perception accuracy among adolescents under different gender (odds ratio [OR] = 1.00, 95% confidence interval [CI]: 0.88-1.15, p = 0.940), place of residence (OR = 0.98, 95% CI: 0.83-1.16, p = 0.800), grade (OR = 1.73, 95% CI: 0.68-4.42, p = 0.250), and family economic level (OR = 0.94, 95% CI: 0.86-1.02, p = 0.140). Egger's linear regression showed that there was no significant publication bias in the primary analysis.

CONCLUSIONS

The current analysis indicates that gender, place of residence, grade, and family economic level were not identified as influencing factors for adolescents' weight perception accuracy. Due to the limitations of the review and included studies, more robust trials are warranted in different social and economic environments to confirm our findings.

The Synergetic Effect of Soft Drinks and Sweet/Salty Snacks Consumption and the Moderating Role of Obesity on Preadolescents' Emotions and Behavior: A School-Based Epidemiological Study

The consumption of ultra-processed foods (UPFs) is high along with the prevalence of emotional and behavioral problems among children and adolescents. The present study sought to investigate the synergetic effect of soft drinks and sweet/salty snacks consumption, and the moderating role of obesity on preadolescents' emotions and behavior. A cross-sectional study was conducted among 1728 Greek preadolescents aged 10-12 and their parents, during the school years 2014-2016. Parental and child characteristics were collected anonymously, through self-administered and validated questionnaires. Among others, soft drinks and sweet/salty snacks consumption was recorded, classifying preadolescents as low or at least moderate consumers, while anthropometric characteristics (height, weight, Body Mass Index (BMI)) were also recorded. Approximately 6 out of 10 preadolescents were characterized by at least moderate consumption of either sweet/salty snacks, or soft drinks, while 22.7% of the participants had at least moderate consumption of both soft drinks and sweet/salty snacks. Boys and preadolescents with a lower level of adherence to the Mediterranean diet, as well as those living in a more obesogenic family environment were more likely to be in the higher consumption groups. When compared to just either the moderate consumption of sweet/salty snacks, or the moderate consumption of soft drinks, the combination of both unhealthy eating habits was associated with significantly higher odds of both aggressiveness and loneliness, while the examined relationships were significantly stronger in overweight/obese children. The positive synergistic effect of soft drinks and sweet/salty snacks consumption on preadolescents' emotions of loneliness and aggressive behavior is even burdened by obesity status highlighting the urgent need for policymakers to take preventive measures to halt the detrimental consequences of UPFs consumption on health outcomes, particularly in overweight/obese children. The importance of the improvement of children's unhealthy eating habits by emphasizing the association between food intake and emotional and behavioral status is highlighted.

Parental Misperceptions of Their Offspring's Weight and Their Strategies for Child's Eating Behavior: A Narrative Review of the Recent Evidence

The aim of the present review was to explore the effect of parental misperceptions of their offspring’s weight status during childhood and early adolescence on weight control strategies and children’s eating behavior. Literature searching was limited to the PubMed database and to the English language from January 2000 to August 2022. Eligible studies had clearly associated parental misperception of offspring’s weight with child eating habits or weight management and eating strategies in childhood to early adolescence. Sixteen studies (14 cross-sectional, 1 longitudinal and 1 with cross-sectional and longitudinal analyses) were included in the analysis. Weight loss attempts and child’s eating behavior were the main outcomes. Sixteen studies found significant associations. Parental misperceptions of their offspring’s weight status do influence their child’s weight and eating behavior, especially in overweight children. Parents tend to follow potentially harmful methods when they overestimate their children’s weight (food restriction) and when they underestimate their children’s weight (pressure to eat). However, additional longitudinal studies are needed to better understand the impact of parental weight status perception on health behaviors and children’s weight gain over time. The potential need for preventive intervention studies is warranted.

Anthropometric, Lifestyle Characteristics, Adherence to the Mediterranean Diet, and COVID-19 Have a High Impact on the Greek Adolescents’ Health-Related Quality of Life

Objective: The study aimed at analyzing the relationship between anthropometric characteristics, lifestyle, and dietary habits, as well as the burden of the pandemic on the health-related quality of life among Greek pupils. Research methods and procedures: On the whole, 2088 adolescents aged 12–18 years from Attica, Greece, were enlisted in this school-based cross-sectional study that took place in May–December 2021. Health-related quality of life was estimated through the KIDSCREEN-27 questionnaire, adherence to the Mediterranean diet—through the KIDMED test. For the empirical and econometric analyses, the Mann–Whitney U and Kruskal–Wallis means comparison tests were utilized; multiple linear regression was used accordingly. Results: The present study provides evidence to the fact that boys, younger adolescents, adolescents living with both parents and with highly educated mothers had a better health-related quality of life. Concerning their eating practices, positive predictors were consuming a better-quality breakfast, having all five meals daily, consuming lunch and dinner with parents, and higher adherence to the Mediterranean diet. Moreover, sufficient night sleep time, fewer hours spent on screen viewing, more frequent walks, and having hobbies were linked to the health-related quality of life with a positive sign. In contrast, negative predictors were higher body mass index and everyday life difficulties due to the COVID-19 pandemic crisis. Conclusions: Greek adolescents’ anthropometric characteristics, BMI, lifestyle and sedentary habits, eating habits, and adherence to the Mediterranean diet were significantly related to their perceived health-related quality of life during the pandemic.

The Role of Milk on Children's Weight Status: An Epidemiological Study among Preadolescents in Greece

Milk consumption contributes greatly to children's diet, playing a pivotal role in the development and structure of bones and the functioning of the musculoskeletal system and the heart. This study investigated the association between the type of milk and childhood overweight/obesity. In the school period 2014-2016, 1728 students aged 10-12 years and their parents participated. The measurement and classification of their weight status were performed through the criteria of the International Obesity Task Force. Among others, the type of milk consumption was recorded. Four categories of the type of milk children consumed were classified (white milk, chocolate milk, both types of milk, and no milk at all). Children consuming only white milk were 33.1% less likely to be overweight/obese in comparison with children who were not consuming milk at all [OR (95% CI): 0.669 (0.516, 0.867), p = 0.002]. The consumption of chocolate milk showed a protective role against childhood overweight/obesity although its association was not consistently significant. This study highlights the significant contribution of milk (and particularly of white milk) consumption to weight management, and thus its promotion should be consistently encouraged. More studies are needed to shed light on the effects of different dairy foods on weight status in childhood.
