Introduction

Diabetes Mellitus has become a major health challenge today worldwide. It represents a spectrum of metabolic disorders irrespective of age. The unprecedented economic development and rapid urbanization in Asian countries, particularly in India has led to a shift in health problems from communicable to non-communicable diseases. Of all the non-communicable diseases, diabetes and cardiovascular diseases lead the list. Diabetic Mellitus is metabolic chronic disease with long term macro vascular and micro vascular complications. Diabetic Mellitus and its complications are one of the leading causes of morbidity including diabetic nephropathy, neuropathy and retinopathy. It is the leading cause of death, disability and blindness. Approximately 80% of blindness is related to diabetic retinopathy. Diabetic is also responsible for 5,800 or 10% of the new cases of blindness reported annually in India. Diabetic Retinopathy (DR) is the leading cause of vision loss in adults aged 20–74 years [1]. From 1990–2010, DR ranked as the fifth most common cause of preventable blindness and fifth most common cause of moderate to severe visual impairment [2]. The burden of diabetes is considerably higher in general population. The knowledge of self-care factors will be very helpful in prevention of diabetic related complications.

India is considered as the diabetic capital of the world. There are approximately 50 million diabetic patients in India. This figure is expected to increase up to 80 million by 2030. Early diagnosis, intensive treatment and consistent dietary pattern along with regular care and follow ups are essential for diabetes patients, which can help to preserve their health and statistically significantly lower the risk of complications [3]. Risk factors for diabetes are well established but little is known about the knowledge regarding diet among diabetic patients. ‘Diabetes has no cure, but it can be well managed through proper diet, medication and exercise.

The Centers for Disease Control and Prevention have identified self-dietary management as a major step in assessing a patient’s knowledge related to the nutritional aspects, treatment, and complications of diabetes [4]. The studies showed poor knowledge of the diabetic patient about proper diabetic diet management. Reported poor knowledge regarding diabetic diet as 81% participants answered less than 50% correct responses. The study concluded that the diabetic type 2 patients should have up to mark dietary knowledge and keep it in practicing well [5].

Founds in a study by using 250 patients with diabetes and 123 healthy hospital nurses at Poland to assess the knowledge concerning popular food products and their impact on blood glucose levels. The study concluded that the level of knowledge concerning products commonly used in diabetic diet among patients with diabetes and hospital nurses was low. Both groups, patients and nurses need education about diabetic diet [6]. Also found in 105 patients with diabetes type 1 and 2 at Poland to investigate the connection between the level of knowledge and way of feeding among them. Interdependence between knowledge level and way of feeding has not been found. It was concluded that improper way of feeding and low level of knowledge can constitute an obstacle to achieve optimal treatment results [7].

There is need to improve the patients knowledge and provide education to them. Educating the diabetic patients on how to manage the disease through balanced diabetic diet is of utmost importance. One of the biggest challenges for health care providers today is how to address the continued needs and demands of individuals with diabetes. It will prevent from diabetes complications.

Conversely, the challenge for the patients is how to maintain the effective dietary pattern to manage their diabetes. Diabetes patients require making many dietary and life style changes simultaneously. Patient education about dietary management will help diabetic patient to maintain normal blood sugar level. Assessment of knowledge of diabetic patients regarding diabetic diet will help us to know the level of understanding of the topic. Research studies on assessment of knowledge of the diabetic patient are limited. Therefore a study was done to assess the knowledge of diabetic patients on diabetic diet.

Materials and Methods

A cross-sectional survey was applied upon 100 diabetic patients to assess the knowledge regarding diabetic diet. The subjects were selected from the medicine and endocrinology OPD in a tertiary care hospital at New Delhi city. Convenient sampling was used. On the basis of the objectives and frame work developed for the study, a structured questionnaire for assessing knowledge was developed. There are two sections of the tool. Section-I consists of socio-demography data which includes age, sex, marital status, educational qualification, family income, area of residence, types of house to live in, occupation, type of the family and educational activity attended. Section–II consists of structured questionnaire for assessing knowledge of the subjects regarding diabetes mellitus and diabetic diet. It comprises 28 multiple choice and 6 dichotomous questions with the options YES and NO. For validation, the tool was submitted to six experts of the area. Experts were selected on the basis of experience and interest in the field of problems. They were requested to judge the items for their clarity, relation and usefulness to the problem. A few alterations and modifications were made. Hindi for the convenience of the subjects/respondents. Reliability of the questionnaire was tested among nursing students in one of the college of nursing, in New Delhi city with Cronbach’s alpha for each set of the questions range within the acceptable limit (>0.7).After obtaining ethical permission, data was collected within a period of 10 days. Purpose of the study was explained and informed consent was taken. The subjects were contacted individually and were assured of confidentiality and anonymity. Questionnaire was administered and subjects were requested to answer each question. Illiterate subjects were been dictated the tool and data was computed by investigator. Analysis of the data obtained, was by using IBM SPSS version 26. Descriptive statistics was used like frequency and percentage. ANOVA and LEVENE’S test were used to further analysis the data.

Results

Table 1: Knowledge score N=100.

Table 1 shows mean Knowledge score 14.46 (maximum score 34) SD ± 4.52. (N=100).

Table 2 shows that majority of samples (50%) belongs to the age group of 31-45. More than half of the subjects (55%) were females. Majority of subjects (71%) were Hindu and 35% of total subjects were educated till the primary level. 74% of the subjects had Pukka house and 54% were living in urban area. 41% subjects were unemployed, 61% were living in nuclear family. Majority of subjects (41%) shows their monthly family income below 10000 rupee. 75% subjects were married and only 25% of the total subjects had attended educational activities on diabetes. There is statistically significant inverse relationship between mean knowledge score and age (P=0.001.).Younger in age had more knowledge. The table shows statistically significant relationship between mean knowledge score and educational status (P=0.001). It shows enhancement in the knowledge with higher education at every step. Relationship between type of house and level of knowledge found statistically significant (P=0.004).Subjects from pukka house were more aware. It shows that subjects who attended any educational activity related to diabetes and diabetic diet have more knowledge (P=0.010).

Table 2: Relationship between knowledge score and socio-demographic variables (age, educational status, type of house, educational activity attended) N=100.

Table 3 shows that there was no influence of gender, religion, marital status, occupation, type of family, area of residence and monthly family income, on knowledge. There was no statistically significant relation between knowledge and gender, religion, marital status, occupation, type of family, area of residence and monthly family income.

Discussion

In this cross sectional survey, applied upon 100 diabetes mellitus patients. The mean knowledge score was 14.46 SD ± 4.52 which was considered poor with maximum knowledge score of 34.Present study found poor knowledge of the patient regarding diabetic diet. Knowledge score was found inverse to age of the patient (P=0.001.) whereas it was found in-line with the level of educational qualification (P=0.001). The subjects from pukka house were more aware about diabetic diet (P=0.004). Subjects who attended any educational activity related to diabetes mellitus and diabetic diet had more knowledge (P=0.010). The knowledge score was independent of gender, religion, marital status, occupation, and type of family, area of residence and monthly family income of the patient.

These findings are supported by PurifineAke-Tano SO. They found that 60.7% patients did not have a good knowledge of the recommended diet for diabetics. Among the patient, 88.5% did not have regular meal times. They did not know that eating fatty meals and fried food was not recommended for diabetics. The study concluded that strengthening nutritional support by therapeutic education section is a key strategy that should be implemented to improve dietary habits [8]. Similarly reported only 19% of the patient had good knowledge, remaining 81% participants answered less than 50% correct responses had poor knowledge. The study concluded that the diabetic type 2 patients should have up to mark dietary knowledge and keep it in practicing well. It will prevent from diabetes complications. There is need to improve the patients knowledge and provide education them [9].

In a study, found that a statistically significant percentage (74.3%) of the study participants had poor adherence to dietary recommendations. According to the survey of participant’s lack of knowledge, lack of diet education, inability to afford the cost of the healthy diet and poor awareness about the benefit of dietary recommendations were the most cited reasons for poor dietary adherence. It was concluded that the rate of non-adherence to dietary recommendation among patients with T2 DM was found to be high in northwest Ethiopia [10]. Study from Nigeria reported that more than 50% of the patients had poor Dietary Knowledge [11]. Similarly inadequate dietary knowledge was reported related to diabetic diet, in 43.42% patients [12]. Similar study reported28.57% of type 2 diabetics had poor dietary knowledge [13].

Present study supported by Wang H. They reported poor nutrition knowledge and practices among patient. The study concluded that Nutritional and eating education was effective in improving diabetic’s nutrition knowledge and practices, and the optimal practice helped them control blood glucose effectively[14]. In a study it was concluded that integration of diabetic based nutrition education with motivation and home gardening was highly recommended.

In contrast to present study reported that all were aware of the importance of diet in the management of DM. But most had difficulty in incorporating this knowledge in to their lives mostly due to social circumstances. The study concluded that despite understanding the importance of dietary control and physical activity in the management of diabetes, adherence to practices were poor, mainly due to lack of clarity of information provided.

Conclusion

This study to assess the knowledge regarding of the patient regarding diabetic diet found that subject had low knowledge. It was apparent that educational qualification and attending any educational activity related to diabetes and diabetic diet increase the level of knowledge of the subjects. Enhancement in the level of knowledge is the felt need for the patient to adhere healthy diabetes diet. Public awareness campaign and other educational activities should be started at every level to educate the diabetic population about diabetic diet. Planned educational programs need to be strengthened by giving more emphasis to the diet plan. By improving the existing educational programs, the knowledge level can be improved so that a diabetic patient can have good control over the blood sugar level to minimize the complications associated with it. Health personnel should make use of opportunity for providing correct knowledge to diabetic patients regarding diabetic diet.
