Discordance between Lifestyle-Related Health Practices and Beliefs of People Living in Kuwait: A Community-Based Study.

OBJECTIVE: To examine the concordance between lifestyle practices and beliefs of people living in Kuwait, and between their lifestyle practices and established evidence-informed recommendations for health. SUBJECTS AND METHODS: A cross-sectional interview questionnaire study was conducted using a convenience sample of 100 adults living in Kuwait (age range 19-75 years). The interview included sections on demographics, and lifestyle-related practices and beliefs related to smoking, diet/nutrition, physical activity/exercise, sleep, and stress. Diet/nutrition and physical activity/exercise benchmarks were based on international standards. Analyses included descriptive statistics and the χ2 test.
RESULTS: Beliefs about the importance of nutrition in lifestyle-related conditions were limited, and this was apparent in participants' dietary habits, e.g., low consumption of fruit/vegetables and multigrains: 16 (16%) and 9 (9%) met the recommended guidelines, respectively. Ninety-nine (99%) believed physical activity/exercise affects health overall, and 44 (44%) exercised regularly. Of the sample of 100, 20 (20%) exercised in accordance with evidence-based recommendations for maximal health. Compared with beliefs about other lifestyle-related behaviors/attributes, respondents believed nutrition contributed more than stress to heart disease, cancer, and stroke, and stress contributed more than nutrition to hypertension and diabetes.
CONCLUSION: In this study, our findings showed a discrepancy between lifestyle-related practices and beliefs, and between each of these and evidence-based recommendations for maximal health, i.e., not smoking, several servings of fruit and vegetables and whole-grain foods daily, healthy weight, restorative sleep, and low-to-moderate stress levels.

Introduction

The “Kuwait National Programme for Healthy Living: First 5-Year Plan (2013-2017)” has been a much anticipated document outlining a multisectorial strategy to curb the prevalence of lifestyle-related noncommunicable diseases (NCDs), especially obesity and type 2 diabetes mellitus, in individuals residing in Kuwait [1]. The prevalence of these conditions is at critical levels and is contributing to significant social and economic burdens to the country [2]. Risk factors associated with these conditions (e.g., elevated levels of cholesterol, blood sugar, and blood pressure; and obesity) are no longer only afflictions of older adults but also of children and young adults [3,4].

Lifestyle-related NCDs constitute a constellation of deadly conditions that are strongly associated with lifestyle choices and behaviors, yet are largely preventable [5]. These diseases include ischemic heart disease, hypertension, stroke, smoking-related conditions such as chronic obstructive lung disease, type 2 diabetes mellitus, obesity, and cancer. In addition to their associated foreboding of premature death, these diseases contribute to substantial disability and reduced quality of life, often over many years in a person's life. Multipronged strategies designed to control and prevent lifestyle-related NCDs are urgently needed in Kuwait comparable to other oil-rich countries in the Middle East [6].

The present study complements the Kuwait National Programme for Healthy Living [1] by identifying factors that may be particularly relevant to inform public health education, and health promotion practice and research in the state of Kuwait. Given no benchmark exists, the objective of this study was to examine the concordance of lifestyle-related practices and beliefs of Kuwait residents, and the concordance of their lifestyle-related practices with evidence-informed recommendations.

Subjects and Methods

The Kuwait University Health Sciences Centre Ethics Review Board approved this study and it conformed to the Declaration of Helsinki. A cross-sectional study based on a standardized interview questionnaire was conducted. Written informed consent was obtained from the participants. A sample of convenience of the people of Kuwait was used. To achieve a representative sample, residents were sampled from a range of public places, e.g., popular shopping areas, parks, and beaches in the Salmiya and Shuwaikh areas.

Adults over the age of 18 years, native or resident of Kuwait for at least 1 year, able to understand Arabic or English, and respond verbally to the questions posed by the interviewer met the inclusion criteria. The exclusion criteria were evidence of cognitive impairment and/or inability to communicate. One hundred individuals were eligible to participate. The sample of convenience consisted of 100 respondents.

Interview Survey Questionnaire

An interview questionnaire was constructed based on previous studies [7,8] that included three sections: demographics; lifestyle-related health status, and practices related to smoking, diet and body composition, physical activity and exercise, sleep, and stress; and beliefs related to these lifestyle attributes and behaviors. In the diet and body composition section, the participants were asked to self-report their weight classifications (i.e., underweight, healthy weight, and overweight), and these were compared to their body mass indices (BMIs) calculated from participants' self-reported weights and heights. This was included because of the epidemic of obesity in Kuwait. The interview was completed on average in 20-30 min.

To maximize the quality of the respondents' responses, the number of interviewers was limited to two, and it was ensured that they were comparably trained in administering the questionnaire and responding to questions. Further, we chose face-to-face data collection given cultural considerations and to limit the possibility of missing data. Also, confidentiality was emphasized to help ensure the accuracy and validity of responses.

Two female interviewers (S.A. and S.A.-M.) with bilingual proficiency in Arabic and English were trained to conduct the questionnaire in a standardized manner. Interviewers approached members of the community sequentially in each preestablished location. After a brief introduction into the study, each potential respondent was asked if he or she would like to participate and, if so, now or later. If the respondent agreed to be interviewed later, a time was arranged.

Reference Standards for Body Composition, Diet, and Physical Activity/Exercise

The World Health Organization (WHO) standards for body composition, specifically BMI, were used [9]. Nutrition guidelines for the Gulf region supported by the WHO Eastern Mediterranean Region were adopted [10]. To illustrate serving sizes, pictures from the Canadian food guidelines [11] were used. These guidelines are not dissimilar to the Gulf guidelines [10,11]. Evidence-informed regular physical activity and exercise levels for optimal health (i.e., moderate to vigorous-intense activity or exercise for 30-60 min, 3-5 days a week, i.e., 150 min a week) were based on the recommendations of the Harvard Medical School Special Health Report on exercise [12] and other established authorities [13].

Statistical Analysis

The data were analyzed using SPSSX software version 17.0 (Chicago, IL, USA). Descriptive statistics were used to summarize and analyze the demographic data. Frequencies and percentages were used to analyze and compare responses to questions about lifestyle health beliefs and practices. χ2 tests were used to assess relationships between nutritional practices and established nutrition guidelines for fruit/vegetables, grains, meat/fish, and dairy consumption. For this descriptive study, we did not stratify the data based on Kuwaiti and non-Kuwaiti, nor gender. α was set at 0.01 to adjust for multiple test comparisons.

Of the 100 respondents, 42 (42%) reported being in excellent health, 55 (55%) in somewhat good health, and 72 (72%) reported they could climb two flights of stairs without difficulty. Self-reported physician-diagnosed conditions that respondents reported included: obesity: 28 (28%); osteoarthritis: 15 (15%); anemia: 10 (10%); irritable bowel syndrome: 13 (13%); and high blood pressure: 10 (10%).

Smoking

Twenty-five (25%) respondents reported being current smokers. Of these, 10 (40%) smoked a pack or more of cigarettes daily. Of the 75 respondents who responded to the question about second-hand smoke exposure, 29 (38.7%) reported such exposure.

With respect to smoking beliefs, all respondents believed that smoking contributed to lifestyle-related NCDs. They believed that this association was less strong for stroke: 69 (69%); hypertension: 64 (64%); type 2 diabetes mellitus: 22 (22%); and osteoporosis: 16 (16%), compared with lung disease: 96 (96%), cancer: 91 (91%); and heart disease: 89 (89%).

All respondents believed that smoking was harmful to health. Of the 98 who responded to the question “what level of smoking was harmful for health”, 13 (13.3%) believed that this level was more than 1 pack/day; for 4 (4.1%), it was between 0.5 and 1 pack/day; and for 81 (81.6%) the critical amount was less than 0.5 pack/day. Of the 100 respondents, 85 (85%) believed that smoking fewer cigarettes was more beneficial than smoking more; however, based on their beliefs, they appeared less knowledgeable about the need for not smoking at all. Although 89-96 (89-96%) of participants believed smoking contributed a great deal to heart disease, lung disease, and cancer, only 64 and 69 (64 and 69%) believed this was true for hypertension and stroke, respectively.

Diet and Nutrition

Of 90 participants who responded to questions about the perceived weight category and their self-reported heights and weights, 39 (43%) respondents were in the healthy BMI range: 18.5-24.9; 7 (8%), however, perceived they were underweight, and 7 (8%) they were overweight. Of the 49 (54%) who were calculated to be overweight, 13 (14%) perceived themselves to be of a healthy weight.

Overall, 61 (67%) respondents were accurate with respect to self-reported weight classification based on BMI, and the remaining 29 (33%) were not. Of the 29 respondents, 8 (8.8%) reported being underweight when they were either healthy weight or overweight/obese, 13 (14.3%) reported being of healthy weight when they were overweight/obese, 7 (7.7%) reported being overweight/obese when they were of healthy weight, and 2 (2.2%) reported they were of healthy weight when they were actually underweight.

Ninety-nine (99%) participants believed that what people eat affects their health. Of several listed common lifestyle-related NCDs, 74 (74%) respondents believed obesity had the greatest association with diet, followed by type 2 diabetes (64; 64%), heart disease (51; 51%), and hypertension (49; 49%).

The daily number of servings of fruit/vegetables, grains, dairy, and meat products consumed by the participants are shown in Table 2. With respect to beliefs about the recommended number of daily servings of various food groups for a balanced diet, 16 (16%) respondents' beliefs were consistent with the recommended daily servings of fruit and vegetables, 9 (9%) for servings of grains; 33 (33%) for dairy products, and 25 (25%) for meat (Table 3). Overall, the number of servings was believed to be lower than recommended for all food categories except for meat and fish, which were consumed in higher quantities than recommended.

A comparison of these dietary practices with respondents' nutritional beliefs showed significant differences for grains (χ21,100 = 10.73, p < 0.01), and for meat and fish (χ21,100 = 7.34, p < 0.01). No differences between their practices and beliefs were observed, however, for vegetables and fruit and milk/dairy products (p > 0.01).

Physical Activity and Exercise

Ninety-eight participants (98%) believed that a person's physical activity and exercise levels affect health. Of several listed common lifestyle-related NCDs, 85 respondents (85%) believed diabetes and obesity had the greatest association with physical inactivity, 79 (79%) with heart disease (79%), 79 with osteoporosis (79%), and 77 with cancer (77%). Hypertension was believed to be less associated with physical inactivity (59%), whereas stroke was believed to be somewhat more associated (70%). With respect to the type and frequency of exercise that was optimal for health, of 98 respondents, 54 (55%) believed daily aerobic exercise was needed, and 26 (27%) respondents believed aerobic exercise 2-3 times per week is required.

All participants (n = 100) responded to the questions about their physical activity/exercise levels, with 44 (44%) indicating that they dedicated time for regular physical activity. Of these, however, only 20 (20%) reported exercising at the evidence-based level of type, intensity, duration, and frequency consistent with optimal health.

Sleep

Of the total 100 respondents who answered the sleep questions, 60 (60%) participants slept between 6 and 8 h nightly, and 25 (25%) were below and 13 (13%) above this range. Fifty-five (55%) respondents reported they did not sleep well (i.e., were not restored on awaking in the morning).

Stress

All respondents believed chronic psychological stress has a negative effect on health. Of the 100 respondents, 47 (47%) reported moderate stress, 31 (31%) high stress, and 22 (22%) low stress. With respect to several listed NCDs, 81 respondents believed stress has a major association with hypertension (81%), 78 with stroke (78%), and 72 with heart disease (72%); and less association with obesity (36%), cancer (35%), and diabetes (20%).

Discussion

In this study, beliefs about the role of nutrition in lifestyle-related conditions were limited, and this was apparent in participants' dietary deficits, such as low consumption of fruit/vegetables and multigrains. The majority of respondents believed physical activity/exercise affected health overall (99%); 44% exercised regularly and 20% exercised in accordance with evidence-based recommendations for maximal health. Compared with beliefs about other lifestyle behaviors/attributes, respondents believed nutrition contributed more than stress to heart disease, cancer, and stroke; and stress contributed more than nutrition to hypertension and diabetes.

Despite the fact that smoking is the leading cause of preventable death. Guidelines for optimal health recommend no amount of smoking is consistent with good health [14]. The prevalence of tobacco smoking is high in Kuwait, especially among men; smoking shisha is also culturally acceptable [15]. The degree to which the relatively low smoking rates in our sample could be explained by smoking alternatives to tobacco could not be established. With respect to beliefs about the deleterious effects of smoking on health, there was no general understanding that even a minimal amount of smoking is harmful.

The greatest disparity between lifestyle-related practices and beliefs of the respondents' was that for diet/nutrition and for physical activity/exercise versus other lifestyle behaviors/attributes (i.e., smoking, sleep, and stress), and lifestyle-related practices related to these, and evidence-based nutrition guidelines and recommendations.

Respondents' belief that a lower consumption of fruit, vegetables, and grains than that recommended for maximal health was optimal, was congruent with their low consumption of these essential food groups. This finding confirmed those of Zaghloul et al. [16]. Thus, health education aimed at both nutritional beliefs through increased knowledge and practice is needed. Healthy nutrition has to be targeted at families as well as children given the reports of rising prevalence rates of overweight and obesity among children [17,18] and impaired glucose regulation in young adults [4].

The fact that only 20% of the entire sample undertook exercise at a level that was commensurate with maximal health benefit is consistent with data from the Kuwait Health Survey showing that three quarters of respondents were inactive consistent with the recommended guidelines of 150 min of exercise at moderate to vigorous intensity weekly [12,13].

Inactivity of the people of Kuwait may be explained by a number of reasons. The people of Kuwait are at risk given their reliance on driving due to a range of environmental and societal factors, including minimal public transportation. Prolonged sitting is an independent risk factor for cardiometabolic diseases [19]. Thus, even if a person engages in regular physical activity, he or she may jeopardize health with prolonged periods of sitting. In addition, recent Canadian data show a strong association between driving and lack of physical activity [20]. Driving travel time has also been associated with increased body weight, a risk factor for type 2 diabetes mellitus [21].

Suboptimal sleep and moderate stress was reported by our respondents. Sleep deprivation has been associated with several NCDs [22,23], thus there is justification for the assessment of the sleep quality and quantity of the people of Kuwait, and intervention in the form of sleep hygiene strategies as needed. Unabated chronic stress including the accumulation of daily hassles has been associated with NCDs and impaired sleep, which further impact physical, cognitive, and mental well-being [24].

The respondents to our questionnaire showed lifestyle-related practices as well as beliefs that were inconsistent with evidence-based recommendations for maximal health. These trends may be explained by a number of factors. First, Kuwait is following the path of western countries in terms of prevalence of lifestyle-related NCDs as it grows economically [6]. Second, previous work had shown that people in Kuwait tend to be overweight, and, perhaps because of this, do not engage in recommended physical activity or are unaware of nutritional guidelines [25]. The investigators explained their findings based on cultural factors. Given the effectiveness of the public policy regarding smoking in Kuwait [26] and other countries, and considerations forthe built-in environment such that “the healthy choice is the easy choice”, such public policy solutions to the crisis of lifestyle-related NCDs in Kuwait generally warrant greater attention.

Based on our findings, knowledge about health beliefs and practices of a population could inform the design of health education campaigns and, in turn, augment people's health status. Extension studies that examine cultural, religious, and traditional practices are indicated as these are strong determinants of smoking practices, diet, activity, sleep, and stress. Aligning health education with culture and traditions as well as religion has been advocated by the WHO for many years [27]. This remains a powerful vehicle for health communication as has recently been demonstrated in a culturally adapted health education program for Saudi women at risk of type 2 diabetes mellitus [28]. In turn, such knowledge could enable health authorities in Kuwait to be proactive in maximizing the health of its population [29]. Our findings provide a basis for further studies to explore concordance of lifestyle practices and beliefs, and guidelines for lifestyle behavior change by targeting knowledge and beliefs as well as practices. Future studies including larger cohorts are needed to explore potential gender differences or differences between Kuwaiti and non-Kuwaiti respondents.

As in other questionnaire surveys, the responses to the items in our questionnaire depended upon the respondents' self-reports which are inherently challenging to validate. Self-reported health status, however, has been reported to have acceptable reliability and validity [30].

Conclusion

In this study, our findings showed a discrepancy between lifestyle-related practices and beliefs, and between each of these and evidence-based recommendations for maximal health, i.e., not smoking; several servings of fruit and vegetables and whole-grain foods daily; healthy weight; restorative sleep; and low-to-moderate stress levels. These findings could support the need for public health education in Kuwait consistent with the Kuwait National Program for health promotion and NCD risk reduction. Such education, however, could be targeted at lifestyle-related knowledge and beliefs of Kuwait's residents as well as practices to reduce the gap between them and, further, to align lifestyle-related practices and beliefs with scientific evidence for healthy living practices. Our findings have provided the basis for future studies aimed at reducing the high prevalence of lifestyle-related NCDs in Kuwait and maximize people's health through attention to lifestyle-related behaviors as well as beliefs.
