Association between type 2 diabetes and chronic arsenic exposure in drinking water: A cross sectional study in Bangladesh
Environmental Health volume 11, Article number: 38 (2012)
Chronic exposure to high level of inorganic arsenic in drinking water has been associated with Type 2 Diabetes (T2D). Most research has been ecological in nature and has focused on high levels of arsenic exposure with few studies directly measuring arsenic levels in drinking water as an index of arsenic exposure. The effect of low to moderate levels of arsenic exposure on diabetes risk is largely unknown thus our study is adding further knowledge over previous works.
This cross sectional study was conducted in 1004 consenting women and men from 1682 eligible participants yielding a participation rate of 60%. These participants are aged > 30 years and were living in Bangladesh and had continuously consumed arsenic-contaminated drinking water for at least 6 months. T2D cases were diagnosed using glucometer following the new diagnostic criteria (Fasting Blood Glucose > 126 mg/dl) from the WHO guideline (WHO 2006), or a self-reported physician diagnosis of type 2 diabetes. Association between T2D and chronic arsenic exposure was estimated by multiple logistic regression with adjustment for age, sex, education, Body Mass Index (BMI) and family history of T2D.
A total of 1004 individuals participated in the study. The prevalence of T2D was 9% (95% CI 7-11%). After adjustment for diabetes risk factors, an increased risk of type 2 diabetes was observed for arsenic exposure over 50 μg/L with those in the highest category having almost double the risk of type 2 diabetes (OR=1.9 ; 95% CI 1.1-3.5). For most levels of arsenic exposure, the risk estimates are higher with longer exposure; a dose–response pattern was also observed.
These findings suggest an association between chronic arsenic exposure through drinking water and T2D. Risks are generally higher with longer duration of arsenic exposure. The risk of T2D is highest among those who were exposed to the highest concentration of arsenic for more than 10 years.
Arsenic is a recognised carcinogen and toxicant [1, 2]. It has a wide range of adverse health effects including cancer of the skin and internal organs, chronic bronchitis, hypertension, and skin lesions such as hyper pigmentation, and hyper keratoses. Chronic arsenic exposure has also been reported to be a potential risk factor for type 2 diabetes [3–6]. T2D is a metabolic disorder characterized by hyperglycaemia, insulin resistance in peripheral tissues, and altered insulin secretory capacity of pancreatic β cells [7, 8]. Type 2 diabetes accounts for 90-95% of all cases of diabetes and is a major public health problem worldwide . Established risks factors of T2D include older age, obesity, physical inactivity, family history, and genetic polymorphisms . In addition, environmental toxicants, including arsenic, have been suggested to play an aetiologic role in developing diabetes [5, 6, 11], although this association is yet to be established.
Previous studies reported a possible association between chronic ingestion of arsenic in drinking water and T2D [5, 6, 12], although some of these studies are inconsistent, and the quality of the data has been questioned [9, 11, 13]. Recently, Chen et al., reported no association between arsenic exposure from drinking water and diabetes mellitus in a study conducted in Araihazar, an upazila (sub-district) of Narayangonj District, Dhaka, Bangladesh . Experimental studies that explored the diabetogenic effects of inorganic arsenic also reported conflicting results [9, 15–17]. Overall, the experimental and epidemiologic evidence is at present insufficient and inadequate to establish a causal association between arsenic exposure and T2D.
At least, 20% of the rural population of Bangladesh has been exposed to naturally occurring arsenic through drinking water . From the public health context, it is therefore important to assess the role of arsenic in drinking water as a factor in the development of T2D in Bangladesh. Our cross sectional-analytical study was designed to examine the association between chronic arsenic exposure and T2D.
Bangladesh is divided into 64 districts, with each district divided into sub-districts named upazilas, and each upazila further divided into a number of unions. Each union consists of a number of villages, each with a number of tube wells from which the inhabitants draw their water for daily usage including drinking and cooking.
The study was conducted from January to July 2009. Ethics approval was obtained from the Bangladesh Medical Research Council (BMRC) and the Human Research Ethics Committee (HREC), The University of Newcastle, Australia.
Study area and population
After careful review of the Bangladesh Arsenic Mitigation Water Supply Project’s (BAMWSP) national survey report, arsenic contaminated areas were selected from the Kandirpar, Gobindogonj, Uttarda and Modaffargonj union of the Laksam upazila, and the Jolmuttar union of the Monohargonj upazila of Comilla; the Sundorpur and Durgapur unions of the Kaliganj upazila of Jhenidah were chosen as low arsenic contaminated areas. A union having > 40% of the tube wells contaminated with arsenic >50 μg/L, of which 25% had arsenic more than 250 μg/L were considered as a high arsenic contaminated area for this study. A union with no tube wells containing arsenic at more than 50 μg/L was considered as a low arsenic contaminated area. These areas were chosen purposively to ensure the study population’s exposure to a wide range of arsenic that enabled us to study the effect of various levels of arsenic on T2D. Comilla and Jhenidah are 100 km south-east and 180 km south-west from Dhaka city, the capital of Bangladesh, respectively. One hundred households were randomly selected from each of the seven unions. Interviewers visited all selected households in each area. All individuals present during the household visit who fulfilled eligibility criteria were recruited in the study after their informed verbal consent was given. Eligibility criteria were as follows: aged > 30 years, history of drinking water from any tube well for a least 6 months continuously, and resident in the study area for at least the preceding 6 months. Those aged less than 30 years or those with a chronic medical condition except T2D were deemed ineligible.
Data collection procedure
Six trained field workers conducted a door to door survey to identify potential participants from the randomly selected households. Since the literacy rate is low in the selected sampling areas in Bangladesh, the study information sheet was read directly in front of potential participants, and the objectives and expectations of the study were comprehensively explained. Trained field workers then obtained informed verbal consent from the participants.
Interviewers collected information on socio-demographics, and drinking water use history by face to face interview using a structured questionnaire. The questionnaire was developed by the researchers and pretested in a neighbouring village similar to the study area. All participants underwent a full body examination by a well-trained physician under sunlight to investigate the presence of arsenical skin lesions i.e., melanosis, leucomelanosis and keratosis. Standing height and weight of each participant were measured with the subjects wearing light clothes and not wearing shoes. Weight was measured in kilograms using bathroom scales (Precision 500gm) that were calibrated daily and zeroed before each measurement. Height was measured in centimetres using a locally made wooden height board with a metal measurement tape attached. All measurements were made according to standard WHO procedures . Fasting blood samples were collected from each participant. Interviewers confirmed the fasting status verbally before collecting the blood samples. All field workers were kept blind to the objectives of the study to reduce observer bias.
A single well water measurement was used to characterize chronic arsenic exposure for each participant. We measured the arsenic content of each tubewell water. In case of participants who changed their arsenic contaminated tubewell following BAMWSP survey, we collected water samples from the previous tubewell as a measure for arsenic exposure. This however, only affected 20 participants. We also collected self-reported information on duration of drinking water from these selected tube wells. Cumulative arsenic (total arsenic) exposure was calculated by multiplying the arsenic content of the tube well with duration of use of the well. Drinking water samples were collected from the selected tube wells, transferred and analysed following standard procedure . Water arsenic analyses were performed at a Water Quality Testing Laboratory in Dhaka using flow injection-hydride generation atomic absorption spectrometry (FIHG-AAS) following the standard procedure . The process involves argon gas as carrier and electrical muffle heater in use to maintain temperature at 850° C. The hydride vapor generation involves 1% aqueous solution of Sodium borohydride and 5ml HCl while 15% aqueous solution of KI is used as reducing agent with one hour holding time before hydride generation. The quality control procedure to measure arsenic in this method involves several measures such as calibration checks, duplicate measurements and participation in inter laboratory comparison exercises. Minimum detection level of arsenic by this method is 3μg/L.
Information on socio-demographic characteristics such as age, sex, income, education and occupation, marital status, drinking water history, smoking history, height, weight, arsenical skin lesions, family history of T2D and hypertension were collected. BMI was also calculated using the standard method (weight in kg / height in meter2) .
Participants were classified as having T2D according to the WHO standard diagnostic criteria: Fasting Blood Glucose > 126 mg/dl or a self-reported physician diagnosis of type 2 diabetes . Fasting Blood samples were collected in the morning and analysed for blood glucose levels using an EZ Smart-168 Glucometer (Tyson Bioresearch, Taiwan). All T2D cases identified in this study were referred to the nearest health facilities for treatment and follow-up.
Data were analysed using Stata statistical analysis software, version 10 (Stata, TX, USA, 2001). Frequency tables and summary statistics were obtained to check missing data, out of range values and to assess distributions of continuous variables, and logic checks were undertaken.
Multiple logistic regressions were done to determine the association between chronic arsenic exposure and T2D, adjusting for potential confounders. For these regression analyses, exposure was initially categorised as < 50 μg/L and >50 μg/L, as 50μg/L is the maximum permissible limit of arsenic in drinking water for Bangladesh ; secondarily analyses were done using quartiles of arsenic levels. To assess the impact of duration of arsenic exposure (up to 10 years and more than 10 years), we categorized the arsenic concentration as < 50 μg/L and >50 μg/L, and >50 μg/L arsenic concentration was sub categorized as 51–250 μg/L and >250 μg/L . Initially univariate analyses such as chi-square tests and univariate logistic regression were undertaken to investigate the relationship between T2D and chronic arsenic exposure. Potential confounders such as participant’s age, sex, education (High school and above; primary class 1–5, no formal education), occupation (agriculture; day labour; housewives, other), marital status (currently married, widowed, divorced, never married, other), total number of household members, income (household’s total monthly income), roof type (straw, tin, concrete, other), smoking history (never, previous, current), body mass index ( <18.5 as malnourished and > 18.5 as normal), and presence of arsenical skin lesions were included in the initial model. Only those variables found to be associated at P<0.25 level of significance in the initial model were included in the final multiple regression model. Additionally, we included BMI in the final regression model although it was not statistically significant at P <0.25 level of significance in the initial model as BMI is a known confounder for T2D. To estimate the likelihood ratio for model comparison adjusting for the clustering effect of tube well (household using the same well), we fitted a random effect logistic regression model using tube well id as the random effect variable. We used the random effect models to estimate likelihood ratio to compare between nested models while adjusting for clusters. After we came up with the final set of relevant covariates we refit a multiple logistic regression model where confidence intervals were estimated using the Huber/White robust ‘sandwich’ estimator of variance, which is based on the within cluster correlation observed in the data. Cuzick's nonparametric test for trend was used to test for trend across ordered groups.
A total of 1682 people were eligible to participate and 1004 actually agreed, yielding a participation rate of 60%. Information on baseline characteristics by their drinking water arsenic concentration is presented in Table 1. Participants’ mean age was 44.9 years (±13.2) and more females (68.4%) participated than males. Of the total, 69.1% participants received no formal education. The majority of the participants (67.2%) performed home duties. More than 98% of participants were married or previously married. Hindus were a minority (23.7%) among the study participants. Average total monthly income per household was 69.5 US$ (±66). Study participants were relatively lean with a mean BMI (kg/m2) of 20.3 (±4.5). Overall, 14.2% of the participants were current smokers, and mean duration of smoking was 22.6 years (±12.9). A total of 1004 drinking water samples were collected and analysed. All tubewell water contained arsenic above the minimum detection limit (3 microgram). An average of 5.5 (±2.2) persons was using each drinking water sample, with a range of 1 to 18 persons. Mean arsenic concentration of the tubewells were 159 μg/L (±198.5) ranging from 10 to 1401 μg/L. The overall prevalence of T2D among the study participants was 9% (95% CI 7%-11%), while 4.7% of the participants reported a family history of type 2 diabetes. Only 38% of the participants with T2D were already diagnosed, with the remaining 62% being diagnosed on blood tests during the study. Diabetic individuals were older and more likely to be current or ex-smokers (Table 2).
Results regarding the association of arsenic concentration and type 2 diabetes are given in Table 3. An increased risk of T2D was observed for arsenic exposure over 50 μg/L with those in the highest quartile category having almost double the risk of type 2 diabetes (OR=1.9 ; 95% CI 1.1-3.5). The odds ratios showed a dose–response pattern with a significant increasing trend in relation with increasing exposure category (p <0.001).We also performed sensitivity analysis excluding participants with lesser duration of exposure (<2years and <5 years) and compared them with participants who were exposed for ≥10 years and did not find any difference to that of a comparison between <10 years and ≥10 years exposure groups.
Therefore, the cumulative effects of arsenic concentration and duration of exposure on T2D are presented in Table 4. The odds ratio estimates show a graded, dose–response pattern as arsenic increases and time exposed increases (p < 0.001). The reference group is those who had concentrations not exceeding 50μg/L for less than 10 years.
We assessed the risk of T2D in people consuming arsenic contaminated drinking water in Bangladesh. The findings suggest an association between chronic arsenic exposure through drinking water and T2D. Risks are generally higher with longer duration of arsenic exposure. The risk of T2D is highest among those who were exposed to the highest concentration of arsenic (>250μg/L) for more than 10 years.
More females than males participated in this study. This is because data was collected during the morning when many of the males were out of the home for their daily work. The overall prevalence of T2D is higher in this study than that reported previously in rural Bangladesh . The prevalence of T2D is also higher in the low arsenic area of Kaligonj relative to rural areas of Bangladesh. This may be due to increased risk of T2D even at the lower concentration of inorganic arsenic in drinking water .
Studies in Taiwan, Bangladesh, and Mexico have all shown an association between high levels of inorganic arsenic in drinking water and increased risk of T2D [5, 6, 26–28]. These studies are limited by the use of ecologic measures of arsenic in drinking water rather than individual measurements of arsenic exposure through drinking water. Data from the studies in Taiwan and Bangladesh were pooled earlier in a meta-analysis  that examined extreme arsenic exposure categories (village drinking water levels or living in a high-vs-low-arsenic area); the pooled relative risk for diabetes associated with high versus low arsenic areas was 2.52 (95% CI: 1.69 – 3.75).
Only a limited number of studies have examined the association of low or moderate exposure to inorganic arsenic with diabetes risk [29, 30]. An early ecological study in Utah, USA found no association between arsenic levels in drinking water and diabetes mortality after controlling for age and sex . A cross-sectional study in Wisconsin, USA that examined the association between arsenic in drinking water and nine self reported chronic diseases found that compared to those with an arsenic exposure <2μg/L, those exposed to 2μg/L -10μg/L and >10μg/L of arsenic in drinking water had an adjusted odds ratio of 1.35 (95% CI, 0.78-2.33) and 1.02 (95% CI, 0.49-2.15), respectively . Wang et al., in a previous study found that hair arsenic levels were associated with elevated plasma glucose levels and with the prevalence of the metabolic syndrome in 660 participants exposed to relatively low arsenic levels in drinking water in Taiwan . Chen JW et al in another study from Taiwan reported a two-fold increased risk of T2D among subjects with total urinary As (U-As) >75 μg/g creatinine as compared with individuals whose U-As was < 35 μg/g creatinine after adjustment for potential confounders . However, Chen Y et al observed no association between chronic arsenic exposure and diabetes mellitus in Bangladesh and they reported a prevalence of diabetes of 2.1%, low BMI (<20kg/m2) in 49% and exposure to <300μg/L of arsenic in 90% of the participants . On the other hand, our study reports diabetes in 9%, low BMI (<20kg/m2) in 55% and exposure to <300μg/L of arsenic in 77% of the participants. The low prevalence of diabetes among arsenic exposed people in the Chen Y et al study might be due to the use of glycated hemoglobin (HbA1C) and glucosuria to identify diabetic individuals, rather than fasting blood glucose and 2-hour blood glucose that were used to identify diabetics in another study . Inaccuracies in BMI determination may have contributed to an underestimation of association with T2D risk in our study. Despite the participants in this study might not be representative to the general population; however the participants staying at home were more appropriate for the study, as their exposure to arsenic concentration was determined from the well water they had been consuming.
The mechanism by which arsenic causes T2D is still largely undefined.
Animal model experimentation suggests that arsenic impairs pancreatic β cell function, particularly affecting insulin synthesis and secretion [32, 33]. The molecular mechanism for this effect may be via adverse effects on insulin signal transduction and the inhibition of gene transcription factors [34–36]. A few non-specific mechanisms such as oxidative stress, inflammation or apoptosis may also increase the risk of developing diabetes .
Important strengths of this study include the use of a large population sample, the direct measurement of arsenic in the subjects’ drinking water, and the adjustment for relevant diabetes risk factors such as age, sex, education, body mass index (BMI) and family history of diabetes. While the public health and research implications of this study are important, some caveats must also be considered. One limitation of this study is that biomarkers of arsenic exposure were not measured. Also, we excluded people with chronic medical conditions which may be related to arsenic exposure, although this would tend to bias towards the null and therefore indicates robustness of our results.
Other limitations include the use of a glucometer to measure fasting glucose as this may give inaccurate results. Validity of this glucometer has not been tested earlier. Therefore, there may be misclassification of T2D. Use of field screening tests to diagnose T2D in relation to explore association with chronic arsenic exposure has been a concern. A few previous studies reported an association between T2D and chronic arsenic exposure using field screening tests such as glucometer for blood, and glucometric strips for glucosuria [28, 37]. Laboratory facilities are still rare or unavailable in rural Bangladesh and portable blood glucose devices are suggested for screening rather than diagnosis for diabetes mellitus . Nevertheless, interviewers were unaware of the arsenic concentration levels of the subjects’ usual drinking water. Therefore, this misclassification is likely to be non-differential, and hence may underestimate the risk. It would also have been desirable to have directly measured individual exposure data over time, as the available water samples reflected only a particular point in time and not the historical exposure. In the absence of any reliable information on past exposure, it was essential to assume that arsenic concentrations from the tube wells had been relatively constant over time. The historical consistency of arsenic concentration is of particular concern with shallow ground water, which might be subject to greater fluctuation than water from a deeper well. However, we assume that any fluctuation of arsenic concentrations is likely to affect the study participants equally. Duration of tube well water use was also obtained from the participants. In the absence of any good documentation of water use, we had to rely on the individual’s recall. The study is cross-sectional and temporality between drinking water arsenic and development of T2D cannot be ensured. Prospective epidemiologic studies in populations exposed to a wide range of inorganic arsenic are needed to confirm this association.
Also many other factors need to be considered in any population studies as diabetes risk increases with age, obesity and individual’s physical activity . Another limitation in this study is that we did not adjust for physical activity. However, we adjusted for obesity in the final model. Furthermore, obesity and physical activity would not be an issue in the rural population in Bangladesh as obesity is much lower  and physical activity may be higher in this context.
Our result adds to the growing body of work indicating an association between chronic arsenic exposure and T2D and provides a graded, dose–response relationship. Such an effect could yield insights into the pathophysiology of diabetes and indicate potential future preventive and therapeutic targets in diabetic patients and warrants future larger prospective studies.
