ABSTRACT
The purpose of the study is to determine the effect of obesogenic environment and sociodemographic characteristics on children’s obesity awareness levels.
The sample of the study was composed of a total of 540 children studying at the 5th grade (63), 6th grade (73), and 7th grade (79) in the private school and at the 5th grade (131), 6th grade (108), and 7th grade (86) in the public school specified between the dates when the study was conducted. “Descriptive Information Form”, “Obesogenic Environmental Evaluation Form (OEEF)” and “Obesity Awareness Scale (OAS)” were used to collect the data.
It was determined that OEEF mean score was higher in children studying in the public school (10.50±2.23) than those studying in the private school (7.77±2.36) and the difference between them was significant. OAS “physical activity” subscale mean score was significantly higher in children studying in the public school.
When OEEF and OAS mean scores were examined according to sociodemographic variables, it was found that there was a significant difference between the groups in terms of some variables. It was determined in the study that the children studying in the public school were affected more by the obesogenic environmental conditions and gender increased the obesity awareness level of the children. Within the scope of the fight against obesity, it is recommended to conduct consciousness-raising and awareness programs related to obesogenic environment in all educational institutions primarily in public schools.
Introduction
Obesity is an important health problem that can cause social, psychological and many medical problems arising from the pathological increase of adipose tissue in proportion to body weight in the cases where the energy intake is more than energy consumption (1). Obesity is not only a chronic disease that negatively affects quality of life and life expectancy but it is also an important health problem of the developing world (2). Obesity is a serious public health problem with an increasing prevalence worldwide. According to the data of the World Health Organization, 6% of girls and 8% of boys in age group of 5-19 years were obese in 2016 (3). The childhood obesity starts frequently in the first year of life, the ages of 5-6 years, and adolescence period (1).
In the development of obesity, heredity, intrauterine factors, diet, culture, environmental factors and psychological factors play a role (1). There are many factors that are responsible for the etiology of obesity. One of these factors is the “obesogenic environment” (causing obesity, gaining weight) supported by overeating and immobility (4,5). The studies conducted about increasing childhood obesity have showed that obesogenic environment and behaviors are an important factor for obesity (4,6). Although dietary options and nutrition environment supporting obesity are regarded as an environmental contribution to obesity, the rapid increase in global obesity rates is associated with the obesogenic environment (7,8).
It is important that people have high awareness against factors causing obesity such as obesogenic environment. In terms of social psychology, “Awareness is a term used to indicate how much people are aware of their attitudes and behaviors”. As awareness increases, behaviors appropriate to attitudes increase. It is used in various ways in daily life such as psychological awareness, political awareness, legal awareness, awareness about environmental issues, obesity awareness, and women’s rights awareness. In this way, problems are handled by raising both individual and mass awareness from general areas to specific and certain issues, measurements are performed and briefly, the society is tried to be changed (9). In recent years, the number of studies investigating the obesity awareness has increased. In their study, Murphy and Polivka (10) reported the awareness of parents of school-age children about obesity and body mass index and more than 80% of the participants reported immobility, malnutrition, lack of control in the children’s diet and overeating as the main causes of obesity. In their study, Fahlman et al. (11) assessed the effect of Michigan Model, an education program about nutrition applied to secondary school students, on their eating habits and awareness and found that it caused significant positive changes in both eating knowledge and behaviors of children. Lee et al. (12) investigated the physical activity perception of students by applying a physical activity program to obese students and found results helping them to better understand their exercise perception. Washington et al. (13) investigated the effect of ecological factors and family in normal and overweight children in preschool period and found that they were effective. In their study, Atlı et al. (14) investigated obesity awareness of secondary school students and they found a significant difference between body mass index and gender. In their study, Sözen and Bebek (15) examined the obesity awareness of university students and found that women had more obesity awareness than men.
In terms of community health, children’s body weight and weight gain tendency should be carefully monitored by healthcare professionals in routine health checks, families should be informed about this issue and necessary measures should be taken (1). In this regard, nurses have an important position in the management of childhood obesity. Nursing approach in obesity management is multidimensional and includes physical, social, and emotional evaluation of the child and his/her family such as health promotion, increasing physical activity, measuring body mass index, height and weight follow up, determining family practices affecting the food intake of the child, being sensitive to family needs, and collaborating with family (16-18).
In the studies on obesity, physical aspect of obesity is generally focused and psychosocial factors are ignored. Number of studies examining the obesogenic environment and obesity awareness levels is still insufficient today. In this respect, the study was designed to determine the effect of obesogenic environment and sociodemographic characteristics on the obesity awareness levels of children.
Material and Methods
Setting and Sample
This descriptive study was conducted in a public primary school and a private primary school in Erzurum city between May and June 2017. The population of the study was composed of children studying in primary schools in Erzurum city. The primary schools in city center of Erzurum were stratified as public and private schools in terms of socioeconomic aspect. Selecting a school from each stratum and including it in the study were conducted by using simple random sampling method. The sample of the study was composed of all of 5th, 6th and 7th graders (n=550) studying in the public and private schools determined. Since institution and parent permissions could not be obtained for participation of 8th grade students due to their preparation for high school exam in Turkey, the study was conducted with 5th, 6th and 7th grade students. As a result of the power analysis conducted in the study, when 535 students were included in the study, it was determined that its size effect was 0.141, power was 95% and α type error estimation was 0.05. By predicting that there would be losses, 550 students were included in the study and the study was completed with 540 students. This number pointed out that the sample size was adequate (19).
Measurement
The “Descriptive Information Form”, “Obesogenic Environmental Evaluation Form”, and “Obesity Awareness Scale” were used to collect the data of the study.
Introductory Information Form
This form, prepared by the researchers based on literature (20-22), is composed of questions about the children’s age, gender, height, weight, school, grade, family type, socioeconomic level, mothers’ age, educational background and occupation, and fathers’ age, educational background and occupation
Obesogenic Environmental Evaluation Form
Obesogenic Environmental Evaluation Form is a questionnaire prepared by Yayan and Çelebioğlu (22) in order to determine obesogenic properties of the environment where the child lives. The form includes 20 questions evaluating the child’s school, neighborhood and home environments in terms of obesogenic properties. In the form, all responses including obesogenic environment properties get 1 point. Accordingly, some questions are reversely scored. While the highest score that can be taken from the form is 20, the lowest score is 0. High score signifies that the child lives in an obesogenic environment (22).
Obesity Awareness Scale
Obesity Awareness Scale was developed by Allen in 2011 to measure obesity awareness in children. The original version of the scale has 23 items and three subscales. The subscales of the scale are obesity awareness, nutrition, and physical activity. The scale has a 4-point Likert type scale from negative to positive (23). Turkish validity and reliability study of OAS was conducted by Kafkas and Özen in 2014. The Turkish version of the scale consists of 20 items and three subscales. The highest score to be taken from the scale is 80; whereas, its lowest score is 20. High score indicates obesity awareness. Cronbach’s Alpha reliability coefficient of the scale was determined as 0.87 (20). In this study, the Cronbach’s alpha coefficient of the scale was found as 0.82. This value shows that the scale has a high reliability.
Data Collection
The data were collected in accordance with the work schedule prepared by the school management by considering the syllabus of all 5th, 6th, and 7th grades in both schools between May and June 2017. According to this schedule, the data collection forms were applied to the students in the classroom environment at the time determined for each class after making the necessary explanations about the forms. It took about 20-30 minutes to complete this process.
Ethical Considerations
Before starting the study, ethical approval from Ethics Committee (2017/3-11), official permission from the Ministry of National Education, written consents from the parents of the children and verbal consents from the children were obtained. “Informed Consent Form” which was prepared for the purpose of obtaining written consents of the parents of the children were distributed in closed envelopes to the parents through their children and their written consents were obtained. Before applying the data collection forms, the children were informed about purpose and benefits of the study and their verbal consents were obtained so that their participation in the study was ensured.
Data Analysis
The data was assessed in the computer environment with SPSS (Statistical Package for Social Sciences) 20.0 package program. Number, percentages, minimum and maximum values and mean and standard deviation were used in the data analysis, and Kurtosis and skewness coefficients were used to determine the compatibility of data to normal distribution. Independent samples t-test and Anova (for normally distributed data) and Mann Whitney-U test and Kruskal-Wallis test (for non-normally distributed data) were used. Cronbach’s alpha coefficient calculation, power analysis and Tukey and Dunnett’s-C analysis as advanced analysis were used. Significance level was accepted as p<0.05.
Results
When the descriptive characteristics of the children were examined, it was determined that 59.1% of the children studying in the private school were in the age group of 10-12 years, 58.1% were boy, 36.7% were 7th graders, 90.2% were the members of a nuclear family, 87.4% expressed their socioeconomic status as high, 70.7% of their mothers had a bachelor’s degree and 52.1% of them were employed, 86.5% of their fathers had a bachelor’s degree and 63.2% were involved in the civil servant/worker group. For the children studying in the public school, it was determined that 68.6% of the children were in the age group of 10-12 years, 51.7% were girl, 40.3% were 5th graders, 78.8% were the members of a nuclear family, 65.8% expressed their socioeconomic status as high, 51.1% of their mothers had primary school degree and 89.5% of them were unemployed, 45.5% of their fathers had secondary school degree and 54.5% of them were involved in the civil servant/worker group (Table 1).
In the study, it was found that obesogenic environmental evaluation form mean score was higher in the children studying in the public school and the difference between them was statistically significant (p<0.05). Although OAS mean scores were higher in children studying in the private school, the result was not statistically significant (p>0.05). OAS physical activity subscale mean score was significantly higher in children studying in the public school (p<0.05, Table 2).
When OEEF mean scores of the children were compared according to age groups, a significant difference was determined between the groups (p<0.05). As a result of the advanced analyses, the significance was found between the children in both age groups studying in the private school and the children in both age groups studying in the public school (Table 3).
When OEEF mean scores of the children were compared in terms of gender in the study, a significant difference was found between the groups (p<0.05). As a result of the advanced analyses, the significant difference between the groups was determined between the girls studying in the private school and the boys and girls studying in the public school (Table 3).
It was found in the study that OEEF mean scores of children in all grade levels of the public school were higher than those in the private school and this difference between the groups was statistically significant (p<0.05). As a result of the advanced analyses, the significant difference between the groups was determined between children studying at all grade levels in the private school and the children studying at all grade levels in the public school (Table 3).
When OEEF mean scores were compared in terms of family types, it was found that there was a significant difference between the groups (p<0.05). As a result of the advanced analyses, it was determined that the significance between the groups was present between the children, who were studying in the private school and living in the nuclear and extended families, and the children who were studying in public school and living in nuclear and extended families (Table 3).
When OEEF mean scores were compared in terms of socioeconomic status, it was determined that there was a significant difference between the groups and the difference was observed between the children in both groups studying in the private school and the children in both groups studying in the public school (p<0.05, Table 3).
Mothers’ educational background was found to be effective on OEEF mean scores (p<0.05). As a result of the advanced analyses, the significant difference between the groups was found to be between the children in all three groups studying in the private school and the children in all three groups studying in the public school (Table 3).
When OEEF mean scores were compared in terms of mothers’ employment status, it was found that there was a significant difference between the groups (p<0.05). As a result of the advanced analyses, the significant difference between the groups was found between the children, who were studying in the private school and had employed and unemployed mothers, and the children, who were studying in the public school and had employed and unemployed mothers (Table 3).
Similarly, when OEEF mean scores were compared in terms of fathers’ educational background, it was determined that there was a significant difference between the groups (p<0.05). As a result of the advanced analyses, the significant difference between the groups was determined between the children, who were studying in the private school and had father with secondary school degree and bachelor’s degree, and the children, who were studying in the public school and had fathers with primary, secondary school and bachelor’s degree, (Table 3).
When OEEF mean scores were compared according to the fathers’ occupation, a significant difference was determined between the groups (p<0.05). As a result of the advanced analysis, the significant difference between the groups was found between the children in all groups studying in the private school and the children who were studying in the public school and had civil servant, self-employed and retired fathers (Table 3).
When OAS mean scores were compared in terms of descriptive characteristics of the children, it was revealed that variables such as age, grade, family type, socioeconomic status, mothers’ education level and employment status, and fathers’ education level and profession were not effective on OAS mean scores of the children (p>0.05). When OAS mean scores were compared in terms of the gender of children, it was determined that there was a significant difference between the groups and the difference between the groups was determined between the boys in the private school and public school and the boys and girls in the public school (p<0.05, Table 4).
Discussion
Obesity is an important health problem that can result in social, psychological and many medical problems (1). The studies conducted on increasing childhood obesity have showed that obesogenic environment and behaviors is an important factor for obesity (4,6).
In the study, obesogenic environmental characteristics of the children studying in the private and public schools were evaluated with OEEF and the mean score of the children studying in the private school (7.77±2.36) was lower than the mean score of the children studying in the public school (10.50±2.23) (Table 2). This result showed that the living spaces of children studying in the public school had more obesogenic properties. When the literature was examined, no study was found investigating the environments of the children in the public and private schools from an obesogenic perspective. In the study conducted by Yayan and Çelebioğlu (22) to investigate the “effect of obesogenic environment and social support for health behaviors on body mass index and body image of adolescents”, they determined that obesogenic environment mean score (13.10±2.75) was higher than the mean score obtained in this study. When the items of OEEF were examined, it can be asserted that there was a difference between the private schools and public schools in the city center of Erzurum in terms of sportive activity areas. In terms of the areas of sports activities and opportunities for activities in the school campus, private schools provided more advantages to children. In relation to this, it can be thought that the school environment of the children in the public school had more obesogenic properties. Sedentary lifestyle and low physical activity level cause overweight and obesity in childhood (24). Overweight in children and adolescents is generally caused by low physical activity and unhealthy diet resulting in excessive energy intake (25). The result of the study is a striking finding, especially in terms of showing that the environments of children studying in the public school should be examined more from obesogenic aspect.
In the study, it was found that OAS mean score of children in the private school was higher than the mean score of the children studying in the public school (Table 2). There are a limited number of studies in literature investigating the obesogenic awareness levels of students studying in private and public schools. Among these studies, the Obesogenic Awareness Scale general mean score determined in the study by Atlı et al. (14) is similar to the score received by the students studying in the private school in the present study (58.28±8.66). The fact that the children studying in the private school had higher obesity awareness may be associated with their living standards, school facilities and awareness of their parents.
When OEEF mean scores of the children studying in the public and private schools were examined in terms of age groups and grade levels in the study, it was found that there was a significant difference between the groups and as the age of children increased, their mean scores increased (Table 3). In the study by Yayan and Çelebioğlu (22), it was found that age affected OEEF mean score and as the age of adolescents increased, their mean scores increased. The result of the study showed that as the age of the children increased, their tendency to obesogenic environment increased.
When OEEF and OAS mean scores of the children studying in the public and private schools were examined in terms of gender in the study, it was determined that there was a significant difference between the groups (Table 3,4). The significant difference for OEEF was caused by the lower mean score of girls studying in the private school. In their study, Çınar and Çavuşoğlu (26) examined the obesity condition according to gender and found that male students had a higher rate of obesity than female students and the difference between male and female students in terms of obesity was statistically significant. Likewise, in another study, Özilbey et al. (27) examined obesity prevalence and eating habits in primary school students in two private and two public schools. As a result of the regression analysis, the obesity rate was found to be higher in boys with high income level. This result in the study suggest that girls paid more attention to body image caused by the fact that girls paid more attention to obesogenic environmental conditions and obesity was seen less. The significant difference for OAS was caused by higher mean score of boys studying in the private school. Atlı et al. (14) found in their study that girls had higher subscales and scale mean scores compared to boys but there was no significant difference. This difference in the study suggested that boys studying in the private school had high obesity awareness.
When OEEF mean scores were examined in terms of family types in the study, a significant difference was determined between the groups and this difference was due to the higher mean score of children studying in the public school (Table 3). In their study, Yayan and Çelebioglu (22) found that obesogenic environmental mean score of adolescents living in the nuclear family was higher but the difference was not found to be statistically significant. Different results of the study may be due to the reasons such as decreased control of families on their children because of high number of individuals in extended family and failure to monitor where, when and what type of food the children eat.
In the study, when OEEF mean scores were examined in terms of socioeconomic status, a significant difference was determined between the groups and this difference was caused by higher mean score of the children in the public school (Table 3). When the literature is reviewed, there is an inverse correlation between socioeconomic status and obesity (28). It is known that in the countries with low national income per capita, children do not eat healthy and measures to protect children from obesity are not taken sufficiently in schools and family (29). Likewise, it is stated that while environmental factors of children living in neighborhoods with low-income support their energy intake, there is insufficient or little opportunities for their expenses (30). In a study investigating “the effect of eating behaviors of primary school students and the eating style of parents on childhood obesity”, more obesity was observed in the school with a moderate and high socio-economic level compared to the school with low socio-economic level (21). In a study conducted by Alphan et al. (31) in 2002 to compare eating habits of adolescents studying in the private and public schools, malnutrition was determined to be higher in students with low socioeconomic status. In 299 children aged between 6-15 years at a primary school with high socio-economic level in 2003 in Bakırköy, Istanbul, it was determined that the obesity prevalence was 8.4% and overweight prevalence was 26.7% (32). In the study by Atlı et al. (31) obesity increase was found to be higher in schools with high socioeconomic level. Different study results may be associated with the fact that the opportunities provided to children studying in private schools are better (health eating conditions, high number of sportive activities, etc.), families with high income level generally have high education level and are aware of the obesogenic environment.
In the study, when OEEF mean scores were examined in terms of education level and employment status of parents, it was found that there was a significant difference between the groups and this difference was due to the higher mean scores of children studying in the public school (Table 3). When the literature is examined, the status and education of mothers is an effective factor on conscious and correct behavior of children in food consumption. It was found out that there was a positive correlation between the education level of mothers and the importance of nutrition and the growth and development of the child (33). Likewise, in the study by Alphan et al. (31), they detected that education levels of mothers of students studying in a private school were high and these children had balanced diet. Since parents who have insufficient knowledge about nutrition education have no idea how children should be fed, body composition of the child deteriorates (34). In the study by Yayan and Çelebioğlu (22), it was found that mothers’ education level and working status had an effect on OEEF mean score but fathers’ education level and working status did not affect OEEF mean score. The study result may be caused by higher awareness levels of parents of children studying in the private school since their education level and working status were generally higher compared to the parents of children studying in the public school.
Study Limitations
At the time of the survey as they prepare for the high school exams in Turkey lack of 8th grade students to participate in research studies is limited.
Conclusions
It was determined in the study that children studying in the public school were more affected by obesogenic environment conditions and gender increased the obesity awareness level of children. Within the scope of the fight with obesity, it is recommended to carry out consciousness-raising and awareness programs related to obesogenic environment in all educational institutions, primarily in public schools.
Providing holistic education and awareness efforts including family, school, children and the people who interact with children about healthy nutrition and importance of physical activity, strengthening the policies related to this issue, monitoring the growth including weight and height follow-up from birth and maintaining and evaluating the growth until the end of adolescence period are important approaches.
