Is overweight associated with health-related quality of life (HRQoL) among Tehranian school children?

The validation of a Farsi version of the Clinical Impairment Assessment (F-CIA) among Iranian adolescent boys and girls

PURPOSE

Although some studies have been conducted to examine general psychosocial impairment in Iran, there is no research to date on clinical impairment secondary to disordered eating in Iranian adolescents. The purpose of this study was to evaluate the Farsi version of the Clinical Impairment Assessment (F-CIA) among Iranian adolescents.

METHODS

A total of 1112 adolescents (age_{M [SD]} = 15.55 [1.59], body mass index [zBMI] _{M [SD]} = - 0.00 [1.0]; 54.6% girls) were recruited from four cities (Tehran [Capital], Tabriz [North-Western], Kurdistan [West], and Rasht [North]) in Iran. After translation and back-translation procedures, the F-CIA, Eating Disorder Examination Questionnaire (EDE-Q), and Beck Depression Inventory-Second Edition (BDI-II) were administered to adolescents. We used confirmatory factor analysis (CFA), measurement invariance, independent samples t tests, Pearson correlation, chi-square tests, and internal consistency to test validity and reliability.

RESULTS

CFA indicated that F-CIA demonstrated good fit to the data and supported a three-factor model. The scale was invariant across gender and zBMI. The F-CIA had good internal consistency (αs = 0.76-0.93) and positive associations (rs = 0.13-0.62; p < 0.001) with zBMI, disordered eating symptoms, and binge/purge symptoms. We found no gender differences across mean scores on the F-CIA, but adolescents with higher zBMI reported higher scores on the F-CIA relative to those with lower zBMIs. Finally, adolescents scoring above CIA cutoffs reported higher zBMI, disordered eating outcomes, and depression.

CONCLUSION

Findings suggested that the F-CIA is a reliable and valid measure of clinical eating disorder-related impairment in Iranian adolescents.

Maternal Emotional States in Relation to Offspring Weight and Health-Related Quality of Life: Tehran Lipid and Glucose Study

BACKGROUND

Maternal characteristics have been known to be associated with parenting practices, which could eventually influence their child's weight and health-related quality of life (HRQoL).

OBJECTIVES

This study aimed to assess the direct and indirect associations of maternal emotional states (depression, anxiety, and stress) with body mass index (BMI) and HRQoL in their children.

METHODS

This study was conducted within the framework of the Tehran lipid and glucose study (TLGS). Participants were the children (n = 231) enrolled in TLGS during 2014 - 2016, who had complete data on maternal emotional states. The body weight and height of children were measured using the standard protocol, and BMI Z-score was determined using Anthroplus. Also, HRQoL in children and emotional states in mothers were assessed using the Iranian version of the pediatric quality of life inventory (PedsQLTM4.0) and the depression, anxiety, and stress scale (DASS-21), respectively. Structural equations modeling (SEM) was used to assess the direct and indirect relations of maternal emotional states with children's BMI Z-score and HRQoL.

RESULTS

Mean age, BMI Z-score, and HRQoL total score in children were 13.8 ± 3.1 years, 0.74 ± 1.5, and 84.7 ± 11.3, respectively. In the mothers, median DASS-21 scores (interquartile ranges) in the three scales of depression, anxiety, and stress were 4 (0 - 10), 6 (2 - 12), and 14 (8 - 20), respectively. Maternal level of education was significantly associated with the DASS-21 score (β = -0.23, 95% CI: -0.37,-0.07). Maternal DASS-21 score was significantly associated with BMI Z-score only in girls (β = 0.25, 95% CI: 0.06, 0.53). Significant determinants of HRQoL in boys were the child's age (β = -0.21, 95% CI: -0.40, -0.01) and maternal education (β = -0.24, 95%CI: -0.44, -0.02) and emotional state (β = -0.24, 95% CI: -0.44, -0.03). The child's age (β = -0.33, 95% CI: -0.53, -0.10) and maternal emotional state (β = -0.31, 95% CI: -0.54, -0.08) were significantly associated with HRQoL in girls.

CONCLUSIONS

The maternal emotional state is an important determinant of HRQoL in children, regardless of their weight status. Further research is recommended to examine the current hypothesized model in rural and suburban populations, taking into consideration more influential factors.

The association between children's food habits, anthropometric parameters and health-related quality of life in Chilean school-age children

Introduction

Introduction: children's food habits have an influence on physical and mental health and should be monitored. Objective: the purpose of this study was to determinate the association between children's food habits (i.e., Mediterranean diet adherence), anthropometric parameters and health-related quality of life (HRQoL) in Chilean schoolchildren. Material and methods: girls (n = 282, 11.86 ± 0.82 years) and boys (n = 352, 12.02 ± 0.87 years) enrolled in public schools were included in this study (n = 634). Body mass index (BMI), waist circumference (WC), waist-to-height ratio (WtHR), body fat (BF), nutritional level and HRQoL were evaluated. Results: the schoolchildren with high nutritional levels reported higher HRQoL (p = 0.018) and presented lower BMI, WC and WtHR (p < 0.001). Likewise, according to the following questions: Have your parent(s) treated you fairly? and Have you felt full of energy? The schoolchildren with high nutritional levels reported the major proportion in very and extremely answers (p < 0.001). The BMI was negatively correlated with HRQoL (r = -0.33, p < 0.05). Beside, children's food habits had significant correlation with HRQoL (r = 0.48, p = 0.002). The BMI (B = -0.41, 95% CI = -0.55, 0.93, p = 0.001) and children's food habits (B = -0.78, 95% CI = -0.09, -0.02, p = 0.002) reported associations with HRQoL. Conclusion: in conclusion, the nutritional level (i.e., Mediterranean diet adherence) and BMI presented associations with HRQoL in Chilean schoolchildren; therefore, it is important to consider these results and develop different strategies in schoolchildren to improve their nutritional levels, as HRQoL represents a measure of happiness or satisfaction with life.

Weight associated factors in relation to health-related quality of life (HRQoL) in Iranian adolescents

Objective

This study aimed to explore body weight factors associated with HRQoL of Iranian adolescents.

Methods

A total of 584 adolescents (12–18 years) were included in this cross-sectional study. Participants were selected using a multi-stage sampling method from schools located in Isfahan city in Iran. Body weight, height and waist circumference of adolescents were measured according to standard protocol and body mass index-for-age was determined using Anthroplus software. Adolescents completed a set of self-administered questionnaires which included questions about perceptions of adolescents regarding their body weight status and adolescents’ satisfaction regarding their body weight. To assess HRQoL, adolescents completed the Iranian version of the Pediatric Quality of Life Inventory™ version 4.0 (PedsQL™ 4.0).

Results

The mean age of participants was 15.1 ± 1.3 years. The overall prevalence of overweight and obesity were higher in boys compared to girls (34.5 vs. 26.7% respectively). More boys (49.5%) had incorrect perceptions regarding their body weight status compared to girls (37.0%), and more girls (39.0%) were dissatisfied with their body weight compared to boys (28.8%). HRQoL scores were not significantly different among body weight status groups except for significantly lower physical functioning scores in underweight adolescents compared to their counterparts (p = 0.049; power = 64%). Based on perception of body weight status, only boys who perceived themselves as underweight or overweight reported lower scores in different subscales of HRQoL compared to those who perceived themselves as normal weight (p < 0.05; power > 85%). In girls, body weight dissatisfaction was significantly associated with poorer HRQoL in psychosocial dimensions, while in boys, body weight dissatisfaction was significantly associated with poorer HRQoL in physical and social functioning subscales (p < 0.05; power > 85%).

Conclusion

In conclusion, impairment in HRQoL mainly depends on adolescents’ perception and dissatisfaction regarding their body weight and less on their actual body weight status. These findings implying that more attention should be paid to body image as an important target for interventions aiming at promoting HRQoL during early years of life.

Comparison of health-related quality of life (HRQoL) among healthy, obese and chronically ill Iranian children

Background

Health-related quality of life (HRQoL) has frequently been compared between both healthy and obese children and healthy and chronically ill children; however, there is glaring lack of evidence regarding comparison of HRQoL in obese children with their counterparts with chronic diseases. Therefore, this study aimed to compare HRQoL among healthy, obese and chronically ill children.

Methods

This cross sectional study was conducted among 802 children (8–12 years) who were recruited via convenience sampling method. Participants were 98 healthy, 102 obese and 602 chronically ill children with six groups of chronic conditions including different types of cancer, rheumatoid arthritis, chronic gastrointestinal, kidney, neurologic and respiratory diseases. HRQoL was assessed using the Iranian version of the PedsQL questionnaire and both reports including child self-report and parent proxy-report were obtained. To compare subscales and total scores of HRQoL among healthy, obese and six groups of chronically ill children, the general linear model was used.

Results

Mean self-reported HRQoL total scores were 73.7 ± 13.3 and 74.6 ± 11.8 in girls and boys respectively; based on the parents’ reports, mean HRQoL total scores were 71.6 ± 15.4 and 71.4 ± 13.0 in girls and boys respectively. From the prespectives of both children and parents, HRQoL total score was significantly lower in obese girls compared to both healthy girls and girls with chronic gastrointestinal, kidney, neurologic and respiratory diseases. Considering both children’s and parents’ reports, HRQoL total score was significantly lower in obese boys compared to both healthy boys and boys with chronic respiratory diseases. In terms of subscales of HRQoL, the impairment of HRQoL in obese children, compared to their counterparts with other chronic diseases, was more common in social functioning and physical functioning subscales, specifically in girls.

Conclusion

Obese children reported poorer HRQoL compared to their healthy counterparts, as well as their counterparts with chronic diseases. Current findings emphasize the important impact of childhood obesity on the perceived health of these children, particularly in the social dimension, underscoring thereby the designing, planning and implementation of health promotion programs for prevention and treatment of childhood obesity.
