Abstract

Introduction: Obesity is a significant public health problem affecting more than half a billion people in both developed and developing countries. Studies on obesity awareness among school students in Saudi Arabia are scanty. A study conducted among school students in Al-Madinah, Saudi Arabia showed that most of students had insufficient knowledge of obesity.

Objectives: The objectives of the study were to determine the level of obesity knowledge of intermediate school students in Majmaah, Saudi Arabia and to determine the relation between students’ nutritional status and their obesity knowledge.

Methodology: The research design was cross-sectional. The sample size was calculated as 350. The data was collected by a pretested questionnaire and medical examination. Weight and height of the students were measured to calculate the Body Mass Index (BMI). SPSS for windows was used for data analysis.

Results: Most of the students had adequate level of obesity knowledge 214 (61.1%). The obese students who had adequate knowledge were 60 (72.3%). The overweight, the normal and the underweight students who had adequate knowledge were 63.4%, 59.6% and 47.3% respectively.

Conclusion: In Conclusion, most school students have adequate knowledge about obesity: however, knowledge of students who are obese or overweight is better than those who are normal or underweight. The study recommends more studies about students’ knowledge of obesity that involve students from all regions of Saudi Arabia.

Introduction

Obesity is a significant public health problem affecting more than half a billion people in both developed and developing countries [1]. In the past four decades the number of obese children worldwide as risen ten folds [2,3]. Worldwide over 340 million children and adolescents aged 5-19 were overweight or obese in 2016 [4,5].

In England between 2014 and 2015, 19.1% of children aged 10 to 11 years old were obese and a further 14.2% were overweight [6]. The estimated prevalence of childhood overweight and obesity in Africa in 2010 was 8.5% and is expected to reach 12.7% in 2020. In India the prevalence of childhood and adolescent obesity was estimated as 19.3% [7]. The prevalence of obesity among school children in the Gulf Countries ranges from 5% to 14% in males and from 3% to 18% in females [8]. In the United Arab Emirates, the prevalence of obesity among children and adolescents is continuously increasing [9].

In Saudi Arabia, the disease is a common health problem and the prevalence among children and adolescents increased significantly [10]. The kingdom is now having one of the highest obesity and overweight prevalence rates worldwide [11]. The prevalence of obesity among the age group 5 to 18 years was 11.3%. The prevalence of the disease among females and males aged of 5-12 years was 11.0% and 7.8% respectively [12].

Regarding knowledge, studies showed that awareness of school children about obesity in Tanzania and Bahrain was moderate and enough respectively [13,14]. Studies on obesity awareness among school students in Saudi Arabia are scanty. A study conducted among school students in Al-Madinah, Saud Arabia showed that most of students had insufficient knowledge of obesity [15].

The objectives of the study were to determine the level of knowledge of intermediate school students in Majmaah Saudi Arabia about obesity, to determine the relation between students’ nutritional status and their obesity knowledge and to determine the effect of parents’ education on the level of students’ obesity knowledge.

Materials and Methods

Study design and population

The study was cross-sectional conducted on intermediate school children in Majmaah, Saudi Arabia whose age was between 12 and 17 years. Female students were excluded from the study.

Sampling

At the level of schools stratified sampling was considered and five schools were chosen. Inside the schools the sample was taken by simple randomization using the table of random selection. The sample size was calculated as 336 taken as 350.

Data collection and analysis

The data was collected by a pre-tested questionnaire and medical examination. The questionnaire respondents were school children themselves. The questionnaire consisted of social data such as age, father and mother education. Education level of the parents was taken by asking the students and information was cross-checked by examination of the school records. If data was inconsistent contact of the parents took place to confirm the information. The questionnaire included examination section to state the BMI data. Nutritional status of the students was performed by measuring the weight and height of the students. The height of the students was measured by a measuring tape while a student is standing, looking straight and without shoes. The weight was measured by a weighing machine (GEEPAS DIGITAL PERSONAL SCALE) while a student was wearing light clothes and without shoes. The BMI was measured by the following formula: BMI= weight (Kg m)/ Height (miter) 2 [16].

To assess students’ Knowledge regarding obesity, Likert scale was employed. Five basic questions about obesity were asked. Students who answered correctly four or five questions were considered as having adequate knowledge about obesity; those who answered correctly three questions were considered to have average knowledge while those who answered correctly less than three questions were categorized as having poor knowledge. The data were analyzed by statistical package for social sciences (SPSS), version 22 (SPSS, Chicago, Illinois, USA). Descriptive statistics was used (frequency and standard deviation). For qualitative data, comparisons between groups were done by the chi-square test. P value less than 0.05 was considered significant and all tests were 2-sided.

Ethical concern

The ethical approval was obtained from the ethical committee of the Basic and Health Research Centre of Majmaah University. Informed consent was obtained from the participant’s parents or guardians. This work was coordinated with the education administration of Majmaah province along with the selected schools.

Results

Table 1 shows the age distribution of the students. Students with age between thirteen and fourteen years were 187 (53.3%). Students with age between fifteen and sixteen years were 160 (48.5%). Only three students were more than sixteen years of age (0.9%).

Table 3 shows the relation between nutritional status and students’ knowledge about obesity. The Obese students have the highest level of obesity knowledge (72.3%). The level of adequate knowledge of underweight, normal weight and overweight were 47.3%, 59.6% and 63.4% respectively. The relation between nutritional status and students’ knowledge about obesity is significant (p=0.007).

Table 4 shows the relation between students’ knowledge about obesity and parents’ education. One hundred and twenty-nine (60.3%) of the students whose fathers had general education have adequate knowledge of obesity compared to 85 (39.7%) of students whose fathers had high education (p=0.19). One hundred and thirtythree (62.1%) of the students whose mothers had general education have adequate knowledge of obesity compared to 81 (37.9%) of students whose mothers had high education (p=0.61).

Discussion

In the current study we found that most of the students have adequate obesity knowledge (61.1%), this finding is inconsistent with studies conducted in Italy and India where only 8.6% and 7.0% of students had adequate knowledge about obesity [15,16]. This finding is also inconsistent with studies conducted in Riyadh and Taif in KSA which revealed inadequate Knowledge of the students regarding obesity. This finding me be explained by the fact that great effort was played by local health authorities to raise awareness of school students about health problems including obesity. Majmaah school health program ranked the first in Riyadh region for the year 2017-2018. The support of college of Medicine, Majmaah University to Majmaah school health program can also play a role in this achievement [17-19]. Our results found that the awareness of students who were overweight and obese was higher than that of underweight and normal (p=0.007). This may be explained that obese children tend to know more about obesity, this may be guided by their parents, unlike those who are normal who show no drive to know about the condition. This finding is inconsistent with other studies which found no significant differences in nutrition knowledge between the obese and non-obese students [20,21]. A research work by Moses N in her study on school students reported an exaggerated concern with obesity regardless of body weight or nutrition knowledge [22].

Our study shows no relation between Father and mother education with their children knowledge regarding obesity (p=0.19 and 0.61). A study conducted in northeast India showed that obesity was more common among the students whose mothers are highly educated: however, in Egypt a study showed that lower parent’s education is a risk factor for child obesity [23,24]. A study in Madina, KSA showed a relation between father education and student’s obesity, most fathers of the obese students had high education level [25].

Conclusion

In Conclusion, most school students have adequate knowledge about obesity: However, knowledge of students who are obese or overweight is better than those who are normal or underweight. The study recommends more studies about students’ knowledge of obesity that involve students from all regions of Saudi Arabia.
