Abstract

Objective

To investigate the barriers to weight maintenance among university students in Kuwait by gender and obesity.

Methods

A sample of 530 students was selected at convenience from four universities in Kuwait (2 public and 2 private). The age of students ranged from 19 to 26 years. A self-reported pretested questionnaire was used to obtain the barriers, which were divided into barriers to healthy eating and barriers to physical activity. Weight and height were based on self-reporting, and the students were grouped into non-obese and obese according to the WHO classification. The response options to barriers were: very important, somewhat important and not important.

Results

The main barriers to healthy eating for both genders were: “Do not have skills to plan, shop for, prepare or cook healthy foods” and “Not having time to prepare or eat healthy food”. In general, there were no significant differences between men and women in barriers to healthy eating. There were highly significant differences between men and women regarding barriers to physical activity (P values ranged from <0.001 to <0.016). “Not having time to be physically active” and “The climate is not suitable for practising exercise” were the main barriers reported. Obese men were more likely to face barriers to healthy eating than non-obese men. There were no significant differences between obese and non-obese women regarding barriers to healthy eating and physical activity.

Conclusion

The findings of this study can be utilized in intervention activities to promote a healthy lifestyle and to combat obesity in Kuwait, and maybe in other Arab countries.

Introduction

Obesity has received a great deal of attention worldwide as one of the main risk factors for non-communicable diseases [1]. The prevalence of obesity in Kuwait, both in children and adults, is considered one of the highest in the world, as data have shown that 78 and 82 % of men and women in Kuwait are overweight and obese, respectively [2]. Obesity is associated with several social, psychological and environmental factors that may interfere with healthy eating and physical activity [3]. Such factors differ across communities, and therefore each community needs to investigate the particular components that may be an obstacle to eating a healthy diet and to practising physical activity.

Studies in Kuwait have focused on factors associated with obesity among children [4, 5] and adults [6, 7]; however, none of these studies have investigated the barriers to weight maintenance. Barriers to healthy eating and physical activity may contribute to obesity. Prior studies in Western countries have reported several social and environmental barriers to weight maintenance [8, 9]. However, our knowledge of the possible barriers that contribute to obesity among Arab communities has been impeded by the limited information on barriers to controlling diet and practising a healthy lifestyle.

Young adults (aged 19–30 years) are rarely investigated in the Arab world, as the focus is mainly on children (<19 years) or adults (>30 years). In Kuwait, Al-Isa [10] found that 34.4 % of university women were overweight or obese; the prevalence among university men was 49.6 % [11]. The prevalence reached an alarming level in 2009 as El-Ghazali et al. [12] found that about 93 % of both male and female university students were overweight or obese, and that their dietary habits were characterized by the high consumption of fast foods and sweets. Among these students, 10.8 % of males and 13.4 % of females were physically active.

The high rate of obesity and the low prevalence of physical activity among university students in Kuwait have created the need to establish a programme to promote a healthy lifestyle for this section of the population. Such a programme would not be effective if it did not include activities to overcome barriers to weight maintenance. To our knowledge, no studies have focused on barriers to weight maintenance among university students in Arab countries in general and in Kuwait in particular. Therefore, the current study aimed to investigate the perceived personal, social and environmental barriers to healthy eating and physical activity among university students in Kuwait, as well as the association of gender and weight status with these barriers.

Methods

Participants

The target group was university students at public and private universities. The total sample comprised 530 students (203 males and 327 females); of these 333 were selected from two government universities and 197 students from two private universities in Kuwait. The ages of students ranged from 19 to 26 years. The students were selected at convenience and interviewed during their break times and lunch break by Kuwaiti medical students. One to two medical students were visited at the colleges and the data collected, either in the cafeteria where the participants gathered for snacking or lunch break or in the main hall of the colleges. The medical students explained the purpose of the study to the participants and gave them the choice to accept to participate in the study or deny. Then the questionnaire was distributed to those who agreed to participate and they were asked to fill it on the spot in the presence of the medical students. The study was ethically approved by the Family and Community Medicine Department at the College of Medicine and Medical Sciences at the Arabian Gulf University, Bahrain. Data were collected during July and August 2010.

Questionnaire

The questionnaire was based on statements related to barriers to healthy eating and physical activity that had been previously published and used a validated self-reported questionnaire on young women [13]. Some statements were modified to adjust them to the Arab culture as the base study was carried out in Australia. The Arabic version of the questionnaire consisted of 10 statements related to barriers to healthy eating and 14 statements related to barriers to physical activity. The barriers were divided into personal, social and environmental. Response options to the statements about the barriers were: not important, somewhat important and very important.

The Arabic version of the questionnaire had been previously tested on 628 Kuwaiti secondary students, and Cronbach’s alpha coefficient reliability test was applied. The values of Cronbach’s alpha coefficient for the statements related to healthy eating were between 0.652 and 0.686, while the values for those related to physical activity ranged from 0.711 to 0.762; this indicated moderate internal reliability, which was very close to the original English version [13]. Detailed information on the validation and reliability of the questionnaire has been described elsewhere [14]. The reproducibility of the Arabic version of the questionnaire used in Musaiger et al. study [14] was measured using Cronbach’s alpha coefficient. It was found that the value of Cronbach’s alpha coefficient for the current questionnaire was 0.877, suggesting a very good reliability to reproduce this questionnaire.

Obesity measurement

Weight and height of the students were provided by self-reporting, and students who did not know their weight and/or height were not included in the study. Obesity was calculated using the body mass index (BMI) according to the recommendations of the World Health Organization [1] as follows: “normal (BMI; 18.5 to <25 kg/m2), overweight (BMI; 25 to <30 kg/m2) and obese (BMI > 30 kg/m2)”. For the purpose of analysis the students were divided into two categories: non-obese (BMI < 24.9) and obese (BMI > 24.9).

Data analysis

The data were analysed using SPSS statistical package, version 17. The Chi-square test was used to measure the association between gender and obesity and the barriers.

Results

Mean values for age and anthropometric characteristics of university students are shown in Table 1. The mean age for men was 21.5 year compared to 20.6 year for women. The difference was statistically significant (P < 0.001). However, there were no significant differences between genders and age, when grouping the age to less than 21 and over 21 years. There were significant differences between men and women in relation to mean weight, height and BMI (P < 0.001).

The percentages of university students in Kuwait reporting of perceived barriers to healthy eating by gender are presented in Table 2. In general, men were more likely to report that these barriers were very important than women. “Do not have skills to plan, shop for, prepare or cook healthy foods” and “Not having time to prepare or eat healthy foods because of university commitment” were the main barriers to healthy eating perceived by the students. For the combined response categories of very important and somewhat important, 69 % of men and 70 % of women reported the first barrier; whereas the proportions reporting the second barrier were 66.5 and 76.8 % for men and women, respectively. There were no significant differences between men and women in perceiving these barriers, except for the barriers related to lack of time to prepare or eat healthy foods because of university commitment (P < 0.012).

The proportions of university students in Kuwait reporting each of perceived barriers to physical activity by gender are given in Table 3. Except for three barriers, there were highly significant differences between men and women regarding barriers to physical activity (P values ranged from <0.001 to <0.016). Men were more likely than women to report most of the barriers to physical activity as not important. The main barriers to physical activity for both males and females were: “Not having time to be physically active” and “The climate is not suitable for practising exercise”. Approximately 38 and 35 % of men reported the former as very important and somewhat important, respectively, compared to 55 and 31 % of women, respectively. The corresponding proportions for the second of these barriers were 35.5 and 42.9 % among men and 58.7 and 30.9 % among women.

The association between obesity among university students in Kuwait with perceived barriers to healthy eating by gender is shown in Table 4. Obese men had a greater tendency to report most of barriers to healthy eating as very important or somewhat important than non-obese men. This phenomenon was not clearly observed among women. There was a significant differences (P < 0.001) between obese and non-obese men in relation to the barrier “Not having time to prepare or eat healthy foods because of university commitment”, as 23.7 % of the obese men reported that this barrier was not important, compared to 45 % of non-obese men. There were no significant differences between obese and non-obese women regarding barriers to healthy eating.

The association of obesity among university students in Kuwait with perceived barriers to physical activity by gender is presented in Table 5. There were statistically significant differences between obese and non-obese men for all three personal barriers (P values were 0.027, 0.005 and 0.012). However, this was not the case for women. Although obese men and women reported that most of the barriers to physical activity were very important or somewhat important, there were no significant differences between the obese and non-obese regarding these barriers, except for the barrier “Feeling shy when practising exercise outdoors” among women, and personal barriers among men.

Discussion

The current study demonstrated that there were several personal, environmental and social barriers related to healthy eating and physical activity facing young adults in Kuwait. However, the magnitude of these barriers varies between men and women, and between obese and non-obese subjects. With regard to barriers to healthy eating, men were more willing to report that these barriers were very important than women. In contrast, men were more prone than women to report that barriers to physical activity were not important. Obesity had a different association with these barriers for men and women. It seems that obese men face more barriers to healthy eating than non-obese men, while this situation existed less among women.

Lack of information on healthy eating combined with not having skills to plan, shop for, prepare or cook healthy foods seem to be important barriers to healthy eating among Kuwaiti young adults. These findings are in agreement with those reported in Western countries [13, 15]. Nutrition education programmes for the public in Arab countries, including Kuwait, have been found to be deficient and outdated [16]. This may lead people to search for nutrition knowledge from other unreliable sources, especially commercial magazines and websites. El-Sabban and Bader [17] found that the nutrition knowledge of university students in Kuwait had several deficiencies in some areas of knowledge; therefore, the investigators recommended the establishment of a simplified compulsory course, focused on healthy nutrition and lifestyle for all university students.

Most people, including university students, depend on their physicians as reliable sources of nutrition information [18]. However, several studies have shown that physicians lack much essential knowledge of nutrition [19, 20]. In Kuwait, it was reported that physicians provided inaccurate nutrition information related to common health problems such as obesity, hypertension and osteoporosis. It has been suggested that a nutrition course should be introduced into medical education at universities, as well as refreshment training courses for physicians [21]. Given the lack of nutrition information among university students and physicians, there is a need to implement educational nutrition programmes in Kuwait and other Arab countries, either through the mass media or school and university curricula.

The support of parents appears not to be an important barrier among university students, which may indicate that the parents advocate that their sons and daughters eat a healthy diet. Parents provide the environment in the home for the early experiences with foods and eating habits [22]. It is well documented that parents play a considerable role in the eating of healthy foods such as fruits and vegetables [23]. The nutritional knowledge and habits of parents have a significant impact on the eating behaviour of their children [24]. Some studies in the West have shown that parents lack adequate knowledge of healthy nutrition [25, 26]. Therefore, the nutrition background and skills of parents can help to promote the healthy eating of the family members.

More than 50 % of Kuwaiti university students in this study perceived that they received less support from friends and teachers for eating healthy foods. In the USA, Stepherd et al. [27] reported that peers and teachers were the least commonly cited sources of nutrition information. However, despite that, several studies have indicated that peers and teachers can be efficiently employed in providing nutrition intervention [28, 29].

A sedentary lifestyle, which includes long periods of viewing television, playing video games, using the internet and using cars for all transportation, have become typical of the lifestyle of Kuwaiti adolescents [4]. Kuwait experienced nutrition transition earlier than most Arab countries, which has resulted in a great change in socio-economic status and a marked alteration in the way of life. The World Health Organization [30] reported that 65 % of Kuwaiti adults aged 15 years and above were less active. Therefore, promoting physical activity among Kuwaiti people has to be one of the main elements of any programme to promote a healthy lifestyle.

This study showed that having a hot climate and not having time to be physically active were the main barriers for both males and females. It is well known that Arab Gulf countries, including Kuwait, are characterized by a long summer season, which may continue for about six months. Therefore, the chance to exercise outdoors during the year is less for Kuwaiti people than it is for those in Western countries. However, lack of time to practise physical activity was also mentioned as a barrier in the Western countries [31].

In general, the differences between men and women in barriers to physical activity in the current study were highly statistically significant, with a higher reporting by women of the categories important and somewhat important for most of these barriers. This could be due to socio-cultural factors that favour men, since in other Arab Gulf countries Kuwaiti women have less access to sports facilities than men. For cultural and religious reasons, many families do not allow their women to practise exercise at the same place as men, to practise exercise outdoors or to use sports dress to exercise outdoors [2]. Therefore, it is not surprising that “Do not have motivation to do physical activity, exercise or sport” was perceived as a barrier more by women than by men in this study.

Although obese university students in this study perceived the barriers to healthy eating as very important or somewhat important more than non-obese students, the differences between the two groups were not significant, except for two barriers among women. This could be attributed to both groups being keen to control their diet and eat some healthy food. Nevertheless, such a finding needs further in-depth investigation, which is beyond the scope of this study. As for the barriers to physical activity, the picture is slightly different. Obese men faced more significant personal barriers than non-obese men. These barriers are: “Do not have motivation to do physical activity”, “Not enjoying physical activity” and “Do not have skills to do physical activity”. This may be due to obese men experiencing more personal problems associated with their weight.

This study has two limitations which should be mentioned. First, weight and height were based on self-reporting, but not on actual measurements. This may affect the prevalence of obesity in the sample. Also, excluding those who did not know their weight and/or height was considered as a limitation, due to the reduced sample size. However, it is strongly believed that university students who reported their weight and height were actually aware of these measurements. Second, the study should have included more socio-cultural barriers, especially those related to physical activity. Lack of data on prevalence of smoking among university students is also considered as one of the limitations, as smoking habits may be associated with some barriers to weight maintenance. Alcohol drinking may also be associated with healthy eating and physical activity. However, it is worth mentioning that the Kuwaiti authority bans selling and consumption of all types of alcoholic drinks. Nonetheless, this study is the first attempt to investigate barriers to weight maintenance among university students in Kuwait and may be the first in Arab countries as well. Its findings can be used as the basis for further in-depth studies and for intervention activities to promote a healthy lifestyle among the Kuwaiti population.

The current health situation of young Kuwait men and women is characterized by the high availability of unhealthy foods coupled with sedentary lifestyle. This environment is promoting a high prevalence of overweight and obesity. Therefore, to combat the epidemic of obesity and related comorbidities, Kuwait authority should first correct the current environment. The results of this study highlighted some of the barriers that are associated with negative nutrition and unhealthy lifestyles in Kuwaiti young people. A preventive plan of action to overcome barriers to healthy eating and physical activity in Kuwait is urgently needed and should take into consideration the support from families and teachers, time management, self-motivation, increased nutrition awareness, socio-cultural variables, and the provision of facilities for university men and women to practice physical activity inside and outside the university. Increasing the availability of healthy foods in university canteens and providing an environment that encourages physical activity are also essential elements for supporting a healthy lifestyle among this age group. We hope that this study stimulates other researchers to carry out further in-depth studies related to factors that are associated with unhealthy eating and sedentary lifestyle in the Arab world.
