This research is to identify and analyze factors related to medication adherence. The design used in this study was a descriptive-analytic design with a cross-sectional approach. The population is type 2 Diabetes Mellitus sufferers of Prolanis Group in Primary Health Care Facilities in the Ponorogo Regency. A sample of 180 respondents was taken by purposive sampling technique. Variable X includes age, gender, education, occupation, income, and length of suffering. Variable Y was medication compliance with type 2 Diabetes Mellitus patients. Data collection used a Morisky Medication Adherence (MMAS-8) questionnaire and was analyzed using the Chi-Square test with a significant level of α <0.05. From the results of the study, it was found that the factors of age, sex, education, employment, income and duration of suffering had a significant relationship with medication adherence for patients with type 2 diabetes mellitus. It is expected that health services develop family and community- based service management. Researchers are further advised to develop programs to improve medication adherence. INTRODUCTION Diabetes mellitus is a group of metabolic diseases with hyperglycemia characteristic that occurs due to abnormalities in insulin secretion, insulin action, or both. Chronic hyperglycemia in diabetes is associated with long-term damage, and dysfunction of several organs, especially the eyes, kidneys, nerves, heart, and blood vessels, which cause various kinds of complications, including atherosclerosis, neuropathy, kidney failure, and retinopathy1. At present, the prevalence of diabetes in the world reaches 230 million people and that number is up by 3% or an increase of 7 million people every year. In 2025 there are an estimated 350 million people who have diabetes mellitus in the world. The World Health Organization (WHO) says that half of the adults with diabetes in the world are in 5 countries; China, India, the United States, Brazil, and Indonesia2. Indonesia ranks 7th with the highest number of people with diabetes mellitus in the world. The International Diabetes Federation (IDF) states that in 2016 Indonesia has around 9.1 https://crossmark.crossref.org/dialog/?doi=10.26714/seanr.1.3.2019.107-111&domain=pdf&date_stamp=2019-12-30 South East Asia Nursing Research, Vol 1 No 3, December 2019/ page 107-111 108 Sulistyo Andarmoyo / Medication Adherence Analysis of Type 2 Diabetes Mellitus Patients million people with DM3. It is estimated that the number could increase to 12.4 million people in 2025 and reach 14.1 million in 20352. One of the regions with the highest number of diabetics is East Java Province with a prevalence of DM sufferers of 2.1%, which ranks 5th in the top 10 of diabetes mellitus prevalence in Indonesia4. The success of DM management to prevent complications is achievable, primarily through adherence to pharmacological therapy. Compliance is a change in behavior according to the instructions given by the doctor in the form of exercise therapy, diet, treatment, and disease control. Indirectly, the level of medication adherence can be measured by the Morisky Medication Adherence Scale (MMAS)-8 questionnaire. The questionnaire is a method for assessing medication adherence in patients with chronic diseases, including diabetes that has been validated by WHO. Non- compliance with taking medication can lead to complications, the risk of hospitalization, and high costs5. Adherence to the treatment of DM is quite important in the management of DM yet still a big problem6. The level of adherence of patients with type 2 DM which is still low compared to type 1 can be caused by polypharmacy and therapeutic regimens which are generally more complex, as well as drug side effects that arise during treatment6. Compliance with medication and taking medication in people with DM have a very important role in controlling blood sugar. This study was conducted to determine the description of compliance with type 2 Diabetes Mellitus patients in the Prolanis (Chronic Disease Management Program) group in primary care facilities in Ponorogo Regency East Java Indonesia. METHODS The design used in this research is analytical descriptive design using a cross-sectional approach. The study was conducted from April 15th to May 30th, 2019, in the Prolanis (Chronic Disease Management Program) group in the primary service facilities in Ponorogo Regency East Java Indonesia. The study sample of 180 patients with type 2 Diabetes Mellitus with inclusion criteria (male or female aged > 18 years; diagnosed with type 2 diabetes, received drug therapy, had attended a regular check-up at least one time, and was willing to take part in the study). Exclusion criteria are patients who have met the inclusion criteria but are pregnant and breastfeeding, illiterate; patients diagnosed with chronic kidney or liver disease and who undergo hemodialysis. Data analysis was done descriptively by describing patient characteristics consisting of age, sex, last education, occupation, income, and duration or the length of suffering. Then tabulation is made. The compliance is measured using Morisky Medication Adherence 8 items (MMAS-8). It is said to be obedient if the total score of respondents answered "yes" on each questionnaire is < 2. It is said to be non- compliant if the total score of respondents answered "yes" on each questionnaire is 3- 8. Data were collected after obtaining patient approval from the Human Research Ethics Committee (UHREC) Sultan Zainal Abidin University Malaysia with Number: UnISZA.C / 2 / UHREC / 628-2 (85) on 8 April 2019 with UHREC code number: UnISZA / UHREC / 2018/46 RESULTS Based on the results of the study in the table above, it can be seen that there are 125 people ( 69.4%) are not compliant to the undergoing treatment programs and there are 55 people (30.6%) who are compliant to the undergoing treatment programs. Based on the age, the highest non- compliance is in the age range > 45 years which is 115 people (63.9%), based on the South East Asia Nursing Research, Vol 1 No 3, December 2019/ page 107-111 109 Sulistyo Andarmoyo / Medication Adherence Analysis of Type 2 Diabetes Mellitus Patients sex the highest non-compliance is female which reaches 115 people (63.9%), based on education, the highest non-compliance is the low education patients with 125 people (69.4%), based on occupation, the highest non-compliance is among working patients which is 125 people (69.4%), based on income, the highest non-compliance is high- income patients with 67 people (37.2%), based on length of suffering, the highest non-compliance patients are those who had a long duration of suffering < 74 (41.1%) 5 years.

There are around 12 of them who refuse to become respondents so that only about 180 respondents meet the inclusion and exclusion criteria of the study. Based on the results of research conducted it can be seen that age, sex, education, occupation, income and length of suffering have a significant relationship to medication adherence to type 2 Diabetes Mellitus sufferers. Age Factors The results of the study showed that the majority of respondents were over 45 years old. These results are consistent with the results of Riskesdas which shows the majority of Type 2 DM patients aged 56-64 years7. The high number of type 2 DM sufferers at age-susceptible is influenced by several causes, among others, pancreatic beta cells have decreased function in old age which can be influenced by the level and duration of insulin resistance8. Chi-square statistical test results showed that the age factor had a significant value of 0,000 (p> 0.05), indicating that the correlation between age and medication adherence was significant. According to the older the age, the lower the level of compliance. This is due to the physiological function of the decline due to aging10. Gender Factor The highest proportion of respondents based on sex is female. The prevalence of DM in women is higher than in men, especially in type 2 DM, because they are likely to be obese due to an increase in body mass index, monthly cycle/menstruation, and menopause which cause them to experience fat accumulation in the body due to the hormonal process11. The results of chi-square the statistical test showed that the sex factor had a significant value of 0,000 (p> 0.05), indicating that the correlation between sexes with medication adherence was significant. States that gender is related to different life roles and behaviors between men and women in society. In maintaining health, women usually take better care of their health than men12. South East Asia Nursing Research, Vol 1 No 3, December 2019/ page 107-111 110 Sulistyo Andarmoyo / Medication Adherence Analysis of Type 2 Diabetes Mellitus Patients Educational Factors Educational factors have a significant value of 0,000 (p> 0.05), indicating that the correlation between education and medication adherence is significant. The results of this study are the same as13, that education has a significant relationship with medication adherence in patients with diabetes mellitus with a value of p = 0.012. The level of education affects a person's learning process, the higher the education obtained, the easier the person gets information, and the more information obtained, the more knowledge will be obtained14. Occupational Factors Someone who does not work is more at risk of developing DM than those who work. That is because the group does not work are generally lacking in physical activities so that the burning of calories in the body or metabolic processes are not as high as the working group. The results of the chi-square statistical test showed that the occupational factor had a significant value of 0,000 (p> 0.05), indicating that the correlation between work and medication adherence was significant. According to other research, a person's work affects physical activity.15 The group not working tends to lack physical activity so that there is no movement of the limbs, this can make them easier to experience DM. Income Factor Income factor has a significant value that is 0,000 (p> 0.05), indicating that the correlation between income and medication adherence is significant. Economic status influences someone to conduct self-care management. State that the high cost of treatment in type 2 Diabetes Mellitus patients is still an important reason in terms of preventing suboptimal levels of adherence16. The Suffering Duration Factor or The Length of Illness The length or the duration of illness affects compliance toward treatment. Barriers to adherence can be caused by complex treatment regimens, duration of treatment, multi-therapy, drug efficacy, and lack of information provided by health care providers. Other barriers are related to socioeconomic problems, memory disorders, psychological problems, and personal beliefs17. Chi-square statistical test results indicate that the duration of the length of suffering has a significant value of 0,000 (p> 0.05), indicating that the correlation between the duration of the length of suffering from adherence to taking medication is significant. Patients with type 2 diabetes mellitus with comorbidities will indirectly consume more complex types of drugs. Complex types of drugs such as the number of drugs, frequency of administration, dosage forms, as well as special drug administration instructions can trigger non- compliance. CONCLUSION The factors of age, sex, education, employment, income and duration of suffering have a significant relationship with medication compliance with type 2 Diabetes Mellitus patients in the Prolanis Group in Primary Health Care Facilities.
