 ABSTRACT

Diabetes, a known medical problem for more than two millennia, provokes complication in many parts of body and increase risk of premature death. Prevalence of diabetes is steadily increasing everywhere, most markedly in the world's low and middle- income countries. Diabetes Mellitus (DM) is a devastating disease but complications of Diabetes Mellitus can be prevented or delayed through proper awareness and preventive measures. The descriptive cross-sectional study was carried out with main objective to find out knowledge regarding diabetic complications among diabetic clients. Using non - probability purposive sampling method, 100 diabetic clients attending medical Out Patient Department of Tribhuvan University Teaching Hospital (TUTH) were selected and data was collected using pretested semi - structured interview schedule. Findings of the study revealed that almost all (90%) respondents had knowledge on major symptoms of hyperglycemia and 82% knew about its immediate management. Regarding hypoglycemia two third (66%) had knowledge on major symptoms of hypoglycemia whereas almost all (92%) had knowledge on its immediate management. Almost all respondents (95%) knew diabetics have increased risk of loss of vision whereas only 13% knew about increase risk of nerve damage. The study showed significant association between knowledge level and educational status (p=0.000), economic status (p=0.008), and participation in diabetes counseling (p=0.005). Based on the findings, it was concluded that respondents' knowledge regarding DM complication is above average. However, there is need of health education on warning symptoms of diabetes complications and their preventive measures.

Key words: Diabetes mellitus, knowledge, diabetes complications.

 


 INTRODUCTION

Diabetes is one of the most common non - communicable diseases of the modern world, affecting 422 million people worldwide and cause an estimated 1.5 million deaths each year.  The  prevalence  of  Diabetes  Mellitus has risen exponentially around the globe in the last 3 decades. Similarly, 108 million people had had Diabetes Mellitus in 1985, the number increased to 422 million by 2016 which is predicted to be doubled by 2030 [World Health Organization (WHO), 2016].

Diabetes is a chronic condition that occurs when the body cannot produce enough insulin or cannot use insulin effectively and is diagnosed by observing raised levels of glucose in the blood. Overtime, hyperglycemia causes damage to many tissues in the body, leading to the development of disabling and life threatening health complications including loss of vision, kidney failure, heart attacks, strokes, leg amputations and heart failure (International Diabetes Federation (IDF), 2016).

In 2015, the International Diabetes Federation's (IDF) Diabetes Atlas estimates that: in high - income countries up to 91% of adults with the disease have type 2 diabetes. Three- quarters (75%) of people with diabetes live in low- and middle - income countries. It is estimated by IDF that 193 million people with diabetes are undiagnosed and are therefore more at risk of developing complications. Furthermore, one in 15 adults is estimated to have impaired glucose tolerance, and one in seven births is affected by gestational diabetes. Both of these conditions are associated with an increased risk of developing type 2 diabetes in later life. Similarly, 215.2 male populations and 199.5 million female populations worldwide are estimated to have diabetes.

According to WHO - Diabetes country profiles 2016, Diabetes in Nepal is the 7th leading cause of death. About 3% of total mortality ratio died because of diabetes. Prevalence of diabetes increased from 4.7% in the year 1980 to 9.5% in the year 2016. Similarly, 1270 males and 1080 females of age group 30 - 69 and 1370 male and 1430 females of age group 70+ died due to diabetes in the year 2016. Above 20 years of age, 14.6% of people residing in urban area and 2.5% of people in rural areas are suffering from diabetes. Prevalence of type 2 diabetes in urban and rural populations was 8.1 and 1.0% respectively [Nepal Diabetes Association (NDA), 2016].

The prevalence of diabetes is steadily increasing everywhere; most markedly in the worlds middle-income countries. Unfortunately, in many settings the lack of effective policies to create supportive environments for healthy lifestyles and the lack of access to quality health care means, prevention and treatment of diabetes are not being pursued. When diabetes is uncontrolled, it and its complications have dire consequences for health and wellbeing, finances of individuals and their families, and the economies of nations. Lack of awareness about diabetes, its complications combined with insufficient access to health services and essential medicines leads to complications such as blindness, amputation, heart disease and kidney failure (Diabetes facts WHO, 2016).

According to WHO Global Report on Diabetes (2016), prevalence of retinopathy in diabetic clients is 35%. Retinopathy causes 1.9% of  moderate  to  severe  vision loss. Prevalence of End Stage Renal Disease in diabetic client is 12 to 55%. Similarly, prevalence of cardiovascular events and lower extremity amputation is 2 to 3 times and 10 to 20 times higher in diabetic patients than non-diabetic patients respectively.

In a study carried out in Peshawar, Pakistan, out of 96 diabetic clients 76 of the patients were illiterate; 36 (37.5%) had good, 24 (25%) had average and 36 (37.5%) had poor knowledge. Between 50-60% patients were aware of different cardiac complications of diabetes mellitus. Awareness regarding other complications was foot ulcer 70 (72.91%), poor wound healing 68 (70.83%), stroke 54 (56.25%), renal disease 64 (66.66%), eye disease 53 (55.20%), hypoglycemia 50 (52.08%) and symptoms of diabetic neuropathy ranging from 47 to 65% (Ullah et al., 2015).

A descriptive study carried out in diabetic clients visiting the diabetic clinic at Sampa Government Hospital, Ghana, out of 630 participants, 325 (51.5%) knew diabetic foot as the most common complication followed by hypertension 223 (35.4%), neuropathy 184 (29.2%), eye disease 112 (17.7%), heart disease 58 (9.2%), and renal disease 34 (5.4%). Comprehensive assessment of level of knowledge on the complications showed that majority 378 (60.0%) of type 2 DM patients did not have knowledge on diabetic complications, 169 (26.9%) had inadequate knowledge on diabetic complication while 82 (13.1%) had adequate knowledge (Obirikorang et al., 2016).

According to the descriptive study conducted among the 100 diabetic out-patients of B.P.Koirala Institute of Health Sciences, Dharan, the most common and frequent chronic diabetic complications were neuropathy (44.4%) followed by cardiovascular (11.9%), retinopathy (19.04%), nephropathy (16.6%) and others (11.3%) in the year 2011 (Maskey et al., 2011).

Diabetes Mellitus is one of the major fast growing non-communicable disease (NCD) threats to global public health. Trends in the incidence of diabetes indicate a disproportionate increase in developing countries due to current rapid demographic transitions from traditional to more westernized and urbanized lifestyles. It is on rise because of whether people they do not have knowledge on diabetic complications or they are neglecting the disease condition. Few studies have been carried out in Nepal in the past years, hence the researcher’s desire to study this topic.

The objective of the study was to find out knowledge on complications of diabetes between type 2 diabetic clients attending medical OPD and Diabetic clinic of TUTH.

 


 MATERIALS AND METHODS

The descriptive cross sectional study was conducted in medical outpatient department and diabetic clinic of Tribhuvan University Teaching Hospital, Kathmandu over a period of 2 weeks including 100 patients. Sample was selected using non-probability purposive sampling  technique.  Sample  size  was  calculated  using   formula (n=Z2pq/ e2) taking 62.5% prevalence of knowledge on diabetic complications reported by Ullah et al. (2005) 95% confidence level and 10% absolute precision). All the clients of both sex (male and female) diagnosed with type 2 DM for more than 3 months attending medical OPD and diabetic clinic of TUTH and those willing to participate in the study were included. Data was collected by semi-structured interview schedule. All participants were asked 17 close-ended questions and they were categorized as good and poor from mean score. All the data were reviewed, organized, and coded. Coded data was entered in datasheet and was analyzed by using descriptive statistics (frequency, percentage, mean and standard deviation) and chi square test was used to find out association between knowledge level and selected socio-demographic variables.

 


 RESULTS

In this study, 100 participants were included, among them 59% were female and 41% were male. Fifty percent of the participants were of age group 40 to 59 years with mean age of 48.49±12.54. Descriptive statistics of the study population, the distribution of age group, sex, educational status, occupation, economic status, family history of DM, and duration of DM are shown in Table 1. Knowledge regarding short term and long-term complications of diabetes shown in Table 2 and Table 3 shows cross tabulation: level of knowledge and selected socio-demographic variables. About 95% of the participants said they got knowledge on diabetic complications from health institutions. With respect to knowledge about complications of DM, 51% had good knowledge and 49% had poor knowledge (Table 4).

 

 

 

 

 


 DISCUSSION

This study reveals that regarding source of information, almost all (95%) of the respondents obtained information about diabetes and its complication from health personnel followed by friends and family. Supporting this result, a research conducted by Menezes et al. (2015), of 100 samples, majority (78%) came to know the information from physician and rest from other different sources.

Regarding knowledge on meaning of diabetes, 56% thought that diabetes is a disease condition in which blood sugar is increased than normal level. Supporting this finding, of 199 patients in a research conducted by Foma et al. (2013) in Gambia, 47% said they knew what diabetes is.

This study shows that 62% of the respondents had knowledge to check blood sugar level monthly in case of uncontrolled DM. Similar to this finding study done by Dinesh et al. (2017), showed that out of 400 samples, 65% of the study participants had knowledge to check their blood sugar monthly. Regarding symptoms of hyperglycemia, almost all (90%) knew about excessive urination and excessive thirst as the major symptoms. Majority    (82%)    of    them   consult    physician    when these sign occurs. Supporting this finding, a research conducted by Mammen and Thankachan (2017), of 100 patients, majority 58% told that frequent urination and excessive thirst are symptoms of hyperglycemia and they seek physicians help when these signs occur.

Majority (74%) had knowledge on the symptoms of hypoglycemia but almost all 92% of them told that taking chocolate/sugar products immediately when symptoms of hypoglycemia occur. Supporting this finding, research conducted by Mammen and Thankachan (2017), of 100 patient only 40% knew the symptoms of hypoglycemia but 74% told that they knew sweets should be consumed when there is hypoglycemic episode.

This study revealed that almost all (95%) knew that diabetic people have higher risk of loss of vision and 81% knew there is increased risk of hypertension followed by increased risk of kidney failure (76%), increased risk of lower limb amputation (72%), increased risk of cardiac problems (68%), increased risk of stroke (38%) and increased risk of nerve damage (13%). There was similarity in a research conducted by Deepali et al. (2017) where out of 120 diabetics, 94.7% knew that diabetes could lead to retinopathy, 90.4% knew that kidneys can also be affected followed by heart problems 64.5%, nerve damage 68.4%. A study done on Malaysia conducted by Qureshi et al. (2014) also demonstrated that 63.5% of diabetics knew that it could lead to loss of sensation in arms and legs.

Regarding knowledge level on diabetes complication, this study showed 51% of the participants had good level of knowledge. Supporting this finding, a research conducted by Deepali et al. (2017) showed that 55.8% out of 120 diabetics had knowledge on diabetes and its complications.  A cross tabulation of socio - demographic characteristics of respondents and their knowledge level showed significant association between knowledge level and educational status (P=0.000), knowledge level and economic status (P=0.008). Supporting this finding, research conducted in Sampa Government Hospital, Ghana, of total 630 participants study showed that there is significant association between knowledge level and education status and knowledge level and economic status (Obirikorang et al., 2016).

This study showed significant association between knowledge and participation in diabetes counseling (P=0.005). Supporting this finding, research conducted by Deepali et al. (2017) knowledge level of people participated in diabetes awareness program was significantly higher. This study showed there is no significant association between family history of DM and knowledge on diabetes complication, which was contradictory to findings of research conducted in Gambia by Foma et al., which showed that history of diabetes in 1st degree relatives, have positive impact on diabetes knowledge.

In other researches, age, sex, occupation and duration of diabetes were found  to  be  positively  associated  with more knowledge but it is not consistent with the current study.

 


 LIMITATIONS

This study was conducted in the Out Patient Department and Diabetic Clinic of TUTH with small sample size and data collection was done by purposive sampling technique, using interview method. Therefore, the findings of the study cannot be generalized.

 


 CONCLUSION

The findings revealed that there was a good knowledge on symptoms and management of hypo and hyperglycemia, complications of DM, and its preventive measures; while only few of them had knowledge regarding warning symptoms of  long-term  complications and risk of nerve damage. Those who were able to read and write, economic status sufficient for 1 year and surplus, and those who had participated in diabetes counseling had higher level of knowledge. The overall level of knowledge regarding diabetes complications among diabetic clients is good.
