1. Introduction
Physical activity (PA) refers to any physical activity produced by the skeletal muscles that consumes energy. According to the World Health Organization (WHO), the first sign of health at the community level is PA [
1]. It is clear that PA plays a crucial role in social and physical development. In addition, PA has been used to maintain weight loss and weight gain and provides physical, social, emotional, and cognitive benefits [
2,
3]. On the other hand, governments have also recognized the large-scale negative impacts of physical inactivity on health-related problems worldwide. In developing and developed countries, chronic health conditions and non-communication diseases, such as obesity, are mainly associated with physical inactivity [
4,
5]. Hypertension, hyperglycemia, smoking, obesity, and a lack of physical exercise are the five major causes of death [
6]. It is noteworthy that men self-reported a decrease in occupational, domestic, transportation, and leisure PA from 350 MET (metabolic equivalent) hours per week in 1997 to 253 MET hours per week in 2006. Women’s PA decreased from 390 MET working hours per week in 1996 to 246 MET working hours in 2006.
Obesity is considered to be the primary cause for many non-communication diseases (NCDs), including diabetes, hypertension, osteoporosis, and stroke [
7]. Obesity is a complex disease involving excess body fat, which has a lack of physical exercise as one of the main causes [
8]. As mentioned earlier, this is a medical problem that increases the risk of developing other diseases and health problems, such as heart disease, diabetes, hypertension, and some cancers [
7]. Obesity is calculated by body mass index (BMI). WHO has developed different BMI guidelines for the global population and South Asia [
9]. For the global population, WHO uses a number of 25 for normal BMI, which ranges from 25 to 30 for overweight, 30 to 35 for class I obesity, 35 to 40 for class II obesity, and 40 or more for obese people in class III. However, in South Asian countries, a normal BMI is 23, overweight is 23–27.5, class I obesity is 27.5–32.5, class II obesity is 32.5–37.5, and the BMI of the class III obese population is 37.5 or above (
Table 1). However, the BMI does not measure body fat directly, so some people, like body-builders, may be categorized as obese even if they do not have excess body fat.
Taking into account the WHO guidelines on BMI in South Asia as a standard, the Hayatabad Medical Complex, Pakistan Endocrine Society (PES), University of Manchester, University of Glasgow, and Khyber Medical College University conducted a real-time study in Pakistan of 19,000 subjects across the country, showing that 29% of the Pakistani population is obese, with 31% suffering from class I obesity, 13% from class II obesity, and 7% from class III obesity [
9]. This indicates that the obesity rate is 20% higher than that of 31% for the rest of the world (20% in class I, 7% in class II, and 7% in class III). Pakistan is the ninth most obese country in the world, and around 3.4 million Pakistani people died because of obesity in 2010 alone [
10]. The risk factors of obesity have been interpreted as a high-fat diet, sedentary work, and motor transport [
11]. According to Farooq et al., the main reason for the increase in obesity in Pakistan is a lack of exercise [
12]. Among Pakistan’s growing population, there is an urgent need to increase the ratio of PA to reduce obesity. As Professor Dr. AH Amir from Hayatabad Medical complex told the participants at the PES’ fifth annual mid-summer endocrine conference, “This real-time research survey provides the most reliable data on obesity prevalence in Pakistan, so it should be used as a call for action” [
9].
The main object of this study is to highlight the rising obesity rates among university employees in Pakistan due to a sedentary lifestyle. Then, the focus is shifted to overcoming this problem mainly by participating in physical activities. In the current study, the impact of physical activities on the obesity of university employees is measured with the help of a self-designed knowledge attitude and practice (KAP) questionnaire, which is used to enhance the knowledge, attitudes, and practices of specific themes [
13,
14,
15,
16]. We used Yin–Yang theory (discussed in the “Methods” section in more detail) as the theoretical framework of the current study, which helped in developing the questionnaire survey. The current study offers a fresh understanding of the relationship between the obesity ratio and physical activity participation rate of Pakistani university employees.
2. Studies on Obesity in Pakistan
Pakistan is the sixth most populous country in the world, with an urban population of 39.1% [
10]. Pakistan is a developing country and is facing many crises in the field of health due to a lack of awareness. In 2015, there were around 56.4 million deaths worldwide, among which 70% died of non-communicable diseases. In total, 1.6 million died of obesity-related health problems [
10]. Obesity is often accompanied by other diseases, and many studies have shown that obesity is a major cause of non-communicable diseases, leading to serious cardiovascular problems, diabetes, and premature death [
17,
18,
19]. In Pakistan, 46% of deaths are caused by NCDs, comprising around 380,000 males and 300,000 females, and the majority of NCD deaths are related to obesity [
17,
18,
19,
20]. The main causes of overweight and obesity in Pakistan are unawareness, high-density diet consumption, and physical inactivity. Notably, studies have shown that people living in Pakistan’s big cities are more likely to be obese than those in rural areas [
21]. However, there are few studies in Pakistan on the link between a lack of physical exercise and obesity, especially among university employees. A few empirical studies have been conducted [
10,
17], but the existing literature may oversimplify the relationship between overweight and sedentary work among university employees. Some studies have focused on the difference between overweight and obesity between urban and rural residents, finding that residents living in urban areas are more likely to be overweight or obese than residents living in rural areas, and a parallel gap was drawn between the workload of employees and sports participation [
19,
22].
5. Discussion
At present, data on the knowledge, attitudes, and practices related to physical activities and obesity are still lacking. This study is the first to highlight university employees’ KAP about PA and obesity in Pakistan using the concept of the Yin–Yang model. The purpose of the current study was to identify the impact of physical activities on obesity through a KAP survey among university employees in Pakistan. According to the basic principles of the KAP survey, an improvement in knowledge will lead to a modification of attitudes and behaviors, thereby reducing the burden of disease and promoting a healthy lifestyle [
11,
35,
36]. In addition, the KAP model emphasizes the beneficial effects of physical practices on health promotion, disease management, and risk reduction [
37]. According to the WHO, the head of the household plays a major role in determining health policies for the family and society and has a significant impact on the health of current and future generations [
38]. Therefore, this study selected teachers and other faculty members from different universities, who are considered as important guides that can lead their households and society towards a healthy lifestyle.
We found that the knowledge about the impact of physical activities on obesity was reasonable. This result indicates that participants understand the consequences of a sedentary lifestyle and were aware that engaging in physical activity and eating a healthy diet can overcome obesity. Only 6.8% of the respondents indicated that they did not know the correlation between physical activity and obesity. Among the respondents, the ratio of the administration staff (5.5%) was higher than that of the teaching staff (2%), possibly because the administration staff among our participants were not as highly educated or had less scientific knowledge about the human body compared to the teaching staff. According to Bookari et al. [
39], knowledge can be the main factor in moving towards a healthier lifestyle. A good attitude is also the foundation of good behavior. A positive attitude helps to improve the level of knowledge and produce appropriate behavior. In this study, most of the participants showed a very positive attitude towards participating in physical activities, and most of them agreed to reduce or control their obesity levels. Positive attitude and knowledge can lead towards the Yang (functional or physically active in this case) part of the Yin–Yang concept. According to the results, there is not a significant difference in obesity and PA-related attitudes between big (Karachi and Hyderabad) and small (Jamshoro and Sukkur) cities (see
Table 6). This indicates that, regardless of whether they live in small or big cities, all respondents had positive attitudes towards PA and obesity-controlling behaviors. As far as practice is concerned, we found that most of the participants (84.8%), despite their high level of knowledge and positive attitudes, did not participate in physical activities at all; the ratio of females was higher than that of males. These results contradict those of some other studies, which argue that an improvement in knowledge will lead to changes in attitudes and behaviors and that knowledge may be the main factor leading to changes in people’s behaviors and habits [
11,
35,
36,
39]. On the other hand, fewer members of the population engage in good/healthy eating habits to control overweight or obesity. For example, 64% of the participants consumed fast/junk/sugary/oily food or soft drinks either daily or once–twice a week, and most of the employees (81.5%) finished their dinner at 8–9 or after 9 p.m., which is not the healthiest time according to WHO guidelines [
38]. These results support the Yin concept, which is related to less energetic qualities, sedentary lifestyle, and unhealthy eating habits. Furthermore, the results showed that only 21% of the participating university employees had a normal weight, while most of the participants (63.1%) were categorized under various classes of obesity (Class I-III). Notably, these results agree with those of some other studies [
9,
10], showing that 73% of the population suffers from obesity of at least one class (class I–III). This makes Pakistan the ninth most obese country in the world. The present study reveals that most university employees in the surveyed areas of Pakistan suffer from obesity problems because of their eating habits and sedentary lifestyles.
This KAP study provides a better understanding of university employees’ behaviors towards obesity and PA by implementing the concept of Yin–Yang and offers valuable information about the knowledge levels among teaching and administration staff, the attitudes of people in big and small cities, and gender-wise differences in their practical habits. These results could be used to plan lifestyle-counselling programs for employees with obesity and/or sedentary lifestyle issues. The results of this study may be significant for future obesity control and enhancing physical activity policies. Research that focuses on institutions such as universities may play a significant role in health promotion and the prevention of health problems. There are, however, some limitations to this study. This study used a KAP survey, which is a first-generation approach in health behavior research. Recently, third-generation theory-based methods and fourth-generation multi-theory-based methods have been used in health-related research. This KAP survey used predefined questions to capture information on the important knowledge, attitudes, and practices related to the most common eating habits and sedentary lifestyle issues [
40]. The area (Sindh province, Pakistan) is large, but the sample size was relatively small, which could have affected the accuracy and reliability of the survey. As a result, the investigators were trained to control the data. Female participants also spoke to a male surveyor. Indeed, the female respondents, who were voluntary participants, felt relaxed and did not seem conservative when talking to the male researchers. Generally, in Pakistani society, it is difficult to obtain information from universities, especially when the participants include females. Our first attempt was met with many rejections. Lastly, the socio-cultural and religious characteristics of the selected sample were homogeneous, which may have resulted in bias. The investigators attempted to recognize any biases to avoid such results.
6. Conclusions
This study on university employees in Pakistan living in Sindh province is the first to use the KAP model based on Yin–Yang theory. In this study, we examined the influence of physical activity participation knowledge, attitudes, and practices (KAP) among university employees on obesity in Pakistan. The research results clearly show that university employees in Pakistan, especially teaching staff, have a good level of knowledge regarding obesity, its causes, and the consequences of physical inactivity. Most employees have a positive attitude about not being overweight or obese by maintaining healthy eating habits and know that they should participate in physical activities; however, they have a very low level of practically applying this knowledge. In terms of the Yin–Yang concept, the knowledge and attitude of Pakistani university employees towards the logic of Yin is very much clear and positive but the practice towards its functional part (Yang) needs to be improved. Furthermore, this study shows that the knowledge, practices, and attitudes of university employees largely affect their BMI status. This study shows that the awareness and attitude of Pakistani residents about obesity and PA is constantly increasing, but their practices need to be improved. Further studies should be conducted to investigate the reasons for not practicing these activities. For example, despite having positive attitudes and sufficient knowledge that participating in physical activities is good for mental and physical development and that obesity is one of the most fatal NCDs, why do Pakistani individuals not adopt healthy eating styles and participate in physical activities?
