Lupine Publishers | TRACK Implementation Among Bangladeshi Population

 Lupine Publishers | Journal of Clinical & Community Medicine


Abstract

With the increasing burden of non-communicable diseases in low-income and middle-income countries (LMICs), biological risk factors, such as hyperglycemia, are a major public health concern in Bangladesh. Optimization of diabetes management by positive lifestyle changes is urgently required for prevention of comorbidities and complications, which in turn will reduce the cost. Diabetes had 2 times more days of inpatient treatment, 1.3 times more outpatient visits, and nearly 10 times more medications than non- diabetes patients, as reported by British Medical Journal. And surprisingly, 80% of people with this so called “Rich Man’s Disease” live in low- and middle-income countries. According to a recent study of American Medical Association, China and India collectively are home of nearly 110 million diabetic patients. The prevalence of diabetes in this region is projected to increase by 71% by 2035. Bangladesh was ranked as the 8th highest diabetic populous country in the time period of 2010-2011. In Bangladesh, the estimated prevalence of diabetes among adults was 9.7% in 2011 and the number is projected to be 13.7 million by 2045. The cost of diabetes care is considerably high in Bangladesh, and it is primarily driven by the medicine and hospitalization costs. According to Bangladesh Bureau of Statistics, in 2017 the annual average cost per T2DM was $864.7, which is 52% of per capita GDP of Bangladesh and 9.8 times higher than the general health care cost. Medicine is the highest source of direct cost (around 85%) for patients without hospitalization. The private and public financing of diabetes treatment will be severely constrained in near future, representing a health threat for the Bangladeshi population.

Background

Bangladesh is among the top 10 countries with the highest rates of projected age-standardized mortality among selected LMICs due to chronic diseases, particularly for CVDs and diabetes [1]. The age adjusted death rate 40 per 100,000 of population ranks Bangladesh 57 in the world, says WHO [2]. Diabetes is one of the four major types of non-communicable diseases that make the largest contribution to morbidity and mortality worldwide. The International Diabetes Federation (IDF) estimated that, worldwide, approximately 425 million people had diabetes in 2017, projected to be 629 million by 2045. Again, worldwide $727 billion was spent in 2017 for treating and preventing diabetes, projected to be US$776 billion by 2045 [3]. In Bangladesh, specifically, the IDF projects the prevalence of diabetes will increase to more than 50% in the next 15 years [4]. About 129,000 deaths were attributed to diabetes in Bangladesh in 2015, as reported by leading research organization ICDDR, B [5]. According to the WHO-Diabetes country profile of Bangladesh in 2016, the physical inactivity was prevailing among 25.1% of population [6]. Around 85% population of age group 25-65 never checks for diabetes [7]. A recent study by British Medical Journal says, 1 in 10 Bangladeshi adults aged ≥18 years have hyperglycemia (among urban residents) [4]. Even in rural Bangladeshi community, undiagnosed diabetes was high, 7.2% found in a 2016 [8] and 10% in 2019. Roughly 20%-30% of adults in rural areas of Bangladesh have abnormal fasting glucose or impaired glucose tolerance, with the prevalence of diabetes (mostly type 2 diabetes) expected to reach 24%-34% by 2030 [9]. And IDF says, there are 7.1 million people with undetected diabetes in Bangladesh and this number will be double by 2025 [10]. Das et al. [11] reported prevalence of dyslipidemia was over 70% to both male and female subjects, which indicates the urgency of lifestyle intervention strategies to prevent and manage this important health problem and risk factor. Among 8400 stroke patients from different hospitals in Bangladesh over a period of sixteen years, diabetic patients were nearly 25% [12]. Prevention strategies should focus on increasing physical activity, weight loss, smoking cessation, and stricter control of hypertension and glycemic level [13]. (Figure 1)

Material and Methods

The TRACK concept

National Eye Health Education Program (NEHEP) developed a tool using the word “TRACK” to help you remember how to stay on track with diabetes. To keep blood sugar level on target and avoid problems with eyes, kidneys, heart and feet, patients should eat right and be active, and may need to take medication. This helps them make choices in eating and being active so body can perform at its best. By regularly monitoring, patients get it on track and prevent long-term health problems [14,15]. TRACK was developed for diabetic retinopathy prevention but in real life it prevents all other diabetic complication by disease progression. The criteria, in short are regular health checkup and compliance of treatment guidelines along with some lifestyle modifications.

Methodology

Research conducted a year-round comprehensive literature search, which included technical newsletters, newspapers journals, and many other sources. The present study was started at the beginning of 2019. PubMed, ALTAVISTA, Embase, Scopus, Web of Science, and the Cochrane Central Register were thoroughly searched. The keywords were used to search for different publishers’ journals such as Elsevier, Springer, Willey Online Library, and Wolters Kluwer which were extensively followed. Medicine and technical experts, pharmaceutical company representatives, hospital nurses, and journalists were given their valuable suggestions. Projections were based on TRACK criteria of regular health checkup by diabetic and non-diabetic Bangladeshi population. There are many studies regarding diabetes in Bangladeshi population. This is the first study so far, where TRACK criteria (suggested by NEHEP of National Institute of Health, England) fulfillment is studied in Bangladesh.

Results and Discussion

TRACK Vs Bangladesh: perplexity of the present situation

Compliance issue: Poor adherence is a well-documented obstacle in therapeutic control of diabetes. For an effective control and prevention of diabetes, 87% of Bangladeshis were noncompliant, compared to 71% of Indians and 52% Europeans [16]. Out-ofpocket expenditure, emotional status, frequency of counseling, patient’s family priorities, availability of medication (mainly insulin) are the factors greatly influence patient compliance to treatment guidelines. In 2016, the median monthly cost of diabetes maintenance was close to $10, approximately 10% of the median monthly income [17]. According to a 2018 BBC record, insulin availability found supplies were low in six countries - Bangladesh, Brazil, Malawi, Nepal, Pakistan and Sri Lanka [18]. Also, huge gap between the number of diabetic patients and doctors are wellknown. The Diabetic Association of Bangladesh (DAB) record shows, except Dhaka and Chittagong, there are no tertiary facilities in Bangladesh to preventing blindness due to diabetic retinopathy [19]. Children with diabetes are still managed by adult physicians or occasionally by adult diabetologists, except in institutions like BIRDEM, and Dhaka Shishu Hospital. Children and adolescents have special needs at different stages e.g., nutrition, schooling, growth, puberty etc. Improving detection, awareness, and treatment strategies is urgently needed to prevent the growing burden associated with diabetes [20].

Overweight issue: Overweight or obese children have a higher risk of becoming obese in adulthood and are at higher risk of associated chronic diseases [21]. Al Muktadir et al. [22] revealed that around 22% to 27% Bangladeshi youth were recorded as obese with different stages of obesity. Another study says nearly 40% Bangladeshi youth, taking fast foods were recognized as overweight where 32% were noted as obese with different phases of obesity and overall prevalence of fast food consumption was about 53.8% [23]. In a newspaper interview, Professor AK Azad Khan, President, Diabetic Association of Bangladesh said 40% school going children of Dhaka city were either obese or overweight [24]. “Children with type 2 diabetes is rising “alarmingly” in Bangladesh. A 300% raise in the last five years”, according to the Changing Diabetes in Children Program of the BIRDEM hospital [25]. A community level study shows 35% of mothers perceived that childhood overweight/ obesity could be a health problem and nearly 70% were not aware of any health consequences of childhood obesity [26]. Another study shows 97.4% students consume fast food contain Monosodium Glutamate which causes obesity and other body discomforts [27]. In a similar study among students of 4 private universities of Dhaka, 98% of the students were well informed about the negative effects associated with excessive fast food consumption, they were still profoundly addicted to it [28]. Prevalence rates of overweight and obesity are higher in urban peoples compared to rural peoples living in Bangladesh. Hoque et.al, 2015 reported higher average annual rate of reduction of underweight was found among wealthier, highly educated, urban-living women, while a higher average annual rate of increase of overweight was found among poorer, uneducated, rural-living women [29]. Tanwi et al. [30] reported prevalence of overweight and obesity was 34% among urban Bangladeshi women, increased by 17.5% between 1996 and 2011 [31]. Another study reveals that a nearly 30% married women in Bangladesh are overweight [32]. Women’s employment status was only associated with overweight or obesity for urban residents. Working urban women had a lower probability of being overweight. Socio-demographic factors including age, education, wealth index, marital status, watching TV and employment status were associated with the increased trend of overweight and obesity [33]. The highest prevalence of overweight and obesity were observed in those women with the highest education level and wealth, larger family size, living in urban areas and not being in paid employment [34].

Lifestyle issues: According to the WHO-Diabetes country profile of Bangladesh in 2016, the physical inactivity was prevailing more than 25% of population. Bangladeshi women more at health risk than men due to inactivity. Two big reasons to diabetes among Bangladeshi people are carbohydrate-dependent food pattern and sedentary lifestyle [35-37]. While males can go outside, socialize and take part in outdoor activities such as cricket or football or cycling, females are often confined to domestic chores and not allowed to go outside freely. Parents are likely to restrict or discourage their daughters from outdoor activities such as recreational walking or bicycling. Young females are vulnerable to crime while travelling and so are more likely to avoid walking. Uddin et.al, 2019 reported that 80% young adults in Dhaka City, did not meet the WHO recommended level of physical activity (150 minutes of moderate- to vigorous-intensity activity per week) for optimal health, with higher rates of insufficient activity among females than males [38]. Unplanned urbanization in the capital is clear, where people have very limited scope for physical activities. Even in the rural areas people now take rickshaw/vans or other rides to go to marketplaces. Evidence shows that prevalence of physical inactivity 35% to 38% in Bangladeshi adults aged 25 years and older [39]. Adults engage in high levels of sedentary behavior during waking hours, said another study [40]. Prevalence of self-reported depression was respectively 47.7% in Bangladesh. Lower frequency of vigorous physical activity was significantly associated with higher rates of depression diagnosed [41]. People with depressive disorders have a 65% greater risk of developing diabetes than the general population, which is a double trouble according to the WHO [42].

Regular health checkup: Despite the high levels of diabetes and intermediate hyperglycemia, awareness and control of the condition is low in rural Bangladesh. In Bangladesh, one in three people over the age of 35 are diabetic or pre-diabetic, only 12% of them have their condition under control [43]. Fottrell et al. [44] reported only 25% of diabetics were aware of their status, women with diabetes were 37% less likely than men to know that they were diabetic and, even among known diabetics, 75% had suboptimal control of the condition. It is mentioned earlier that 1 in 10 Bangladeshi urban adult (aged ≥18 years) have hyperglycemia, with dyslipidemia prevalent over 70% male and females. Among those aged over 35, the Bangladesh Demographic and Health Survey (BDHS) reported that approximately 25% had abnormal fasting glucose [45]. The glycated hemoglobin (HbA1c) method does not require the candidate to fast for eight hours or take glucose and he or she can have the test done by the HbA1c method any time [46]. However, for individuals diagnosed with diabetes, screening is associated with a reduction in mortality and cardiovascular disease risk [47].

Tobacco smocking: Tobacco kills more than seven million people a year worldwide and responsible for 1 in 5 deaths in Bangladesh, according to the WHO, kills more than 161,000 people on average every year [48]. A number of experimental and clinical studies suggest that smoking decreases insulin sensitivity, and indirectly role plays in elevated blood sugar and LDL, decreased HDL and postprandial lipid intolerance [49-57]. A 2018 survey by BRAC University shows several risk factors of diabetes includes smoking (almost 60%), abdominal obesity (43.3%), hypertension (14.3%), depression (43%) whereas the incidence of routine bodily exercise (only 1.3%) and the habit of consuming seasonal fruits as well as vegetables (8.6%) remain significantly low among the people of Bangladesh [58]. Bangladesh has been identified as a highachieving country for several tobacco control measures, including tobacco taxation, health warning labels and anti-tobacco massmedia campaigns. The high level of achievement for Bangladesh in cigarette taxation is, however, contradicted by an increase in per capita cigarette consumption [59]. Urban male smokers in Bangladesh consume more cigarettes than bidis and smoke more per day than rural smokers. More than half of Bangladeshi men over the age of 25 years smoke cigarettes or bidis, small handmade cigarettes containing about one fourth the amount of tobacco found in cigarettes [60]. Despite the reduction in overall tobacco use, the male smoking prevalence in Bangladesh is still high at 37% [61]. Although, government is taking initiatives from administration, more than one fourth (25.5%) of the police personnel in Bangladesh are currently smokers and this should be intervened [62].

Other Issues:

a)  Climate and environment: Not only food and lifestyle, global warming also plays an important role in diabetes prevalence. A Netherlands based study in CNN Health says, “a 1-degree Celsius rise in environmental temperature could account for more than 100,000 new diabetes cases per year in the USA alone” [18]. A similar study says Bangladesh will exceed 35-degree Celsius before the end of the century [63]. Consuming arsenic contaminated food grains could be another reason of high diabetes prevalence [64]. In sex-stratified analyses with 641 subjects from rural Bangladesh, Paul et.al, 2019 reported arsenic exposure (50.01-150 μg/L) showed a clearer pattern of dose-dependent risk for hyperglycemia in females than males [65]. Again, 15% of expecting women are diagnosed with gestational diabetes among these 60% contribute to permanent diabetes within 10 years, says Dr Samsad Jahan [66] (professor of Obstetrics and Gynecology, BIRDEM).

b)  Skipping meals: Breakfast skipping is highly prevalent among urban adult population with significant association of obesity in Bangladesh [67,68]. reported skipping breakfast by public university students for cost saving [69] and Bipasha et al. [28] reported the same by private university students due to late sleep and rush for classes in the morning. Either way, skipping breakfast hikes both obesity and diabetes risk [70].

c)  Fatty and fried food after religious fasting: It is common knowledge that fasting has myriad health benefits. Fasting during Ramadan is significantly associated with decrease in blood lipid profile, blood pressures, glucose, and HbA1C level among diabetic patients [71-77]. The total energy intake decreases during Ramadan, whereas the dietary fat consumption increases because of an augmentation of fatty food that does not occur during other periods [78]. Following Prophetic tradition, it is customary to open the fast with dates, which is unique in its nutrient content (β-Dglucan, a soluble fiber) that gives the stomach a ‘full’ feeling [79].

d)  Food adulteration: ICDDR, B, estimated 150 food items in the country. More than 50% of the food samples they tested were adulterated reported by the Institute of Public Health (IPH). Undoubtedly human health is now under the domination of formalin, in Bangladesh about 400 tons of formalin is being imported which are goes to human stomach, creates deadly mistreats on long term exposure [80]. Several studies highlighted formaldehydeinduced neurodegeneration, diabetes risk and diabetes-associated cognitive impairments [81-84]. Even more unfortunate is the fact that nefarious practice of food adulteration increases exponentially during the month of Ramadan in Bangladesh, according to a study of European Journal of Sustainable Development Research [85]. The number of patients suffering from cancer, diabetes, and kidney diseases is on the rise due to food adulteration [86-89].

e)  Child marriage: According to UNICEF, Bangladesh has the fourth highest prevalence rate of child marriage in the world, and the second highest number of absolute child brides - 4.5 million. Around 30% of girls in Bangladesh married before the age of 15 and nearly 80% got married before the age of 18 [90- 92]. The prevalence of nutritional deficiency was relatively higher among rural, illiterate and early married women and among those with a low standard of living [93]. Child marriage, low-birth-weight, mother nutrition and diabetes closely related to each other [46], [93-96].

f)  Low Health Literacy (LHL): In low-income countries such as Bangladesh, the less than optimum use of services could be due to LHL. Emphasis on health literacy has been inadequate. And also, health service delivery is pluralistic with a mix of public, private and informally trained healthcare providers [97]. Despite the high levels of diabetes and intermediate hyperglycemia, awareness and control of the condition is low [44]. In a cross-sectional study in urban population of Bangladesh, more than 60% of the diabetic patients had inadequate functional health literacy of them and nearly 90% had inadequate glycemic control (HbA1c>8%). Therefore, Mehzabin et al. [98] concluded that LHL is consistently associated with inadequate glycemic control. LHL also indicates that the health promotion techniques are not used appropriately, and it is linked to the declining health status of the people and results in low compliance to disease prevention programs. Also, Islam et al. [99]2018 concluded that diabetes-related health literacy in rural Bangladesh is a major factor associated with diabetic retinopathy (DR) screening [99]. Diabetes prevention and control efforts in this population must include large-scale awareness initiatives which focus not only on high-risk individuals but the whole population. Innovations in increasing diabetes knowledge and health behavior change are recommended specially for females, those with lower education and less income [100].

g)  Malnutrition & other social challenges: Mother nutrition and diabetes situation is already discussed. Very little is known about the occurrence of T1DM in resource-poor countries and particularly in their rural hinterlands. Bangladesh is among the 20 countries where 80% undernourished children are living. Underweight (weight-for-age z-score <-2) among children aged less than five years is more than 40% and nearly one-third of women are undernourished with body mass index of <18.5 kg/ m2 in Bangladesh [101]. The IDF atlas estimated the incidence of type 1 diabetes in Bangladesh as 4.2 new cases of T1DM/100,000 children (0-14 years)/year, in 2013 [20]. The social challenges faced by T1DM children are numerous. Many of them are poor, with little access to education. They are often considered a burden on the family, especially girls; they have little prospect of getting married or being employed. Diabetes is likely to be hidden from society, prospective spouse and employer, often with far-reaching consequences. Lack of motivation, inability to manage common complications e.g., hypoglycemia, sick day management, drop out from the clinic (which may be due to lack of motivation or extra cost involved in travel), psychological issues, are other common problems.

Conclusion

The prevalence of type 2 diabetes showed an increasing trend in both urban and rural population in Bangladesh. People with no education, lower socio-economic status, and those who lived in disadvantaged regions in terms of education and economic profile are found lacking diagnosis, treatment, and control of diabetes. Emphasizing medication adherence with multiple comorbid diseases should be strongly considered in future diabetes management programs to improve glycemic control in patients with type 2 diabetes. Recently, Telenor Health and DAB have launched the first- ever diabetes management service, Dia360, to help people with diabetes manage their blood sugar levels and reduce risks of complications. People can enroll in three DAB centers in Dhaka- Bangladesh Institute of health and Sciences, BIRDEM General Hospital, and the National Health Network Hospital. It has more than 400,000 diabetics registered at its tertiary center, BIRDEM in Dhaka. However, the most important thing is patient education, that the modern world is giving the highest priorities. Rich or poor, privileged or unprivileged, all segment of population should be brought under the arena of compliance through patient education, at least by health campaign. Both government, profit taking NGOs and pharmaceutical companies should take initiatives in this regard.
