Abstract
Background Type 2 diabetes elevates the risk of severe outcomes in COVID-19 patients, with multiple studies reporting higher case fatality rates. Metformin is a widely used medication for glycemic management. We hypothesize that improved adherence to metformin may lower COVID-19 post-infection mortality risk in this group. Utilizing data from the Mexican Social Security Institute (IMSS), we investigate the relationship between metformin adherence and mortality following COVID-19 infection in patients with chronic metformin prescriptions. Methods This is a retrospective cohort study consisting of 61,180 IMSS beneficiaries who received a positive polymerase chain reaction (PCR) or rapid test for SARS-CoV-2 and had at least two consecutive months of metformin prescriptions prior to the positive test. The hypothetical intervention is improved adherence to metformin, measured by proportion of days covered (PDC), with the comparison being the observed metformin adherence values. The primary outcome is all-cause mortality following COVID-19 infection. We defined the causal parameter using shift intervention, an example of modified treatment policies. We used the targeted learning framework for estimation of the target estimand. Findings Among COVID-19 positive patients with chronic metformin prescriptions, we found that a 5% and 10% absolute increase in metformin adherence is associated with a respective 0.26% (95% CI: -0.28%, 0.79%) and 1.26% (95% CI: 0.72%, 1.80%) absolute decrease in mortality risk. Interpretation Subject to the limitations of a real-world data study, our results indicate a causal association between improved metformin adherence and reduced COVID-19 post-infection mortality risk.

Abstract
BACKGROUND This study was conducted to adapt the Adherence to Asthma Medication Questionnaire (AAMQ-13) into Turkish. METHODS The research was conducted in the pulmonology outpatient clinic of a state hospital in Nigde/Turkey. The sample consisted of 229 volunteers with asthma for at least one year. First, language and content validity were assessed. After evaluating the language validity and content validity of the questionnaire, internal consistency, split-half reliability, and construct validity were examined. Questionnaire and demographic data were analyzed using numbers, percentages, dependent and independent groups t-tests, correlation analysis. RESULTS The AAMQ-13-TR has a Cronbach's alpha (α) score of 0.90 (p < 0.001). It has a split-half reliability coefficient of 0.86. The confirmatory factor analysis (CFA) shows that the factor structure of the AAMQ-13-TR agrees well with the two-factor model of the original questionnaire. CONCLUSIONS This study presented sources of evidence of validity of AAMQ-13-TR in Turkish population.

Abstract
Introduction Prior primary studies have examined the prevalence and factors associated with glycaemic control among patients with type 2 diabetes mellitus, but studies with evidence-based synthesis of the primary data remained unknown. Hence, we aimed to determine the prevalence of poor glycemic control and identify determinants of poor glycemic control in patients with type 2 diabetes in Ethiopia. Methods We performed searches in the online databases of PubMed, Google Scholar, Scopus, Science Direct, and the Cochrane Library. Microsoft Excel was used to extract data, and STATA statistical software (v. 16) was used for analysis. Publication bias was explored by forest plots, Begg's rank test, and Egger's regression test. To check for heterogeneity, I2 was computed. Subgroup analysis was conducted based on region and publication year. In addition, the pooled odds ratio for associated factors was calculated. Results Out of 1,045 studies assessed, 23 studies were included fulfilling our inclusion criteria. In all, 6,643 individuals were enrolled in the study. It was estimated that 61.11% of type 2 diabetes patients had poor glycemic control (95% CI, 57.14-65.19). The subgroup analysis by study region and publication year revealed that the highest prevalence was observed in the Addis Ababa region (68.57%) and studies published before 2019 (61.76%), respectively. Poor glycemic control was associated with older age > 50 years (AOR = 2.12; 95% CI: 1.27-2.97), not attending formal education (AOR = 3.60; 95% CI: 2.75, 4.46), having diabetes for longer duration (10 years; AOR = 2.57; 95% CI: 1.65-3.49), having comorbidity (AOR = 2.43; 95% CI: 2.05-2.80), and low adherence to diabetes management (AOR = 3.67; 95% CI: 2.41-4.92). Conclusion Our findings indicate a high prevalence of poor glycemic control among people with type 2 diabetes in Ethiopia. Being older, not attending formal education, having a longer duration of diabetes, having comorbidity, and having low adherence to diabetes management were all associated. Therefore, we recommend health organizations implement measures to monitor and control patients' blood glucose levels. Patient education and training of healthcare professionals could serve as a short-term strategy to achieve adequate glycemic control.

Abstract
Background and Objectives: The objective is to evaluate medication adherence level (MA) and the relevant determinants of MA among patients with type 2 diabetes mellitus (T2DM) monitored in ambulatory settings by general practitioners. Materials and Methods: A cross-sectional study was conducted among patients with T2DM monitored in a GP practice in Sofia, Bulgaria (September-December 2022). All patients were interviewed according to a predesigned questionnaire after granting informed consent. MA level was evaluated through the Morisky-Green four-item questionnaire, and health-related quality of life was evaluated by EQ-5D-5L and VAS (visual analogue scale). Data were aggregated and statistically evaluated. Results: The total number of observed patients was 93. Around 48.4% of patients were female, and 90.3% of patients were between 50 and 80 years of age. Multimorbidity was identified among 70% (n = 65) of the respondents. High and medium levels of MA were revealed in 64.51% and 33.3% of respondents, respectively. Patients treated with insulin secretagogues were most adherent to the therapy (n = 83.3%) in comparison with the other treatment groups. The onset of the disease, professional status, age, gender, number of therapies, and quality of life did not affect the level of MA (p > 0.05). VAS scores among nonsmokers (VAS = 63.16 ± 20.45 vs. 72.77 ± 14.3) and non-consumers of alcohol (VAS = 63.91 ± 19.34 vs. VAS = 72.54 ± 15.98) were statistically significant lower (p < 0.05). A significant related factor for MA was years lived with diabetes (OR = 3.039, 95% CI 1.1436-8.0759, p = 0.0258). The longer the disease duration, the more the odds for a high MA level increased. Conclusions: The number of nonadherent diabetic patients in Bulgaria is low, which might be evidence of patients' concern about their own health and understanding about the importance of prescribed therapy. Further comprehensive study with additional patients is required to confirm the results and investigate the predicting factors for a high level of MA.

Abstract
Within the past several years, a considerable body of research on adherence to diabetes regimen has emerged in public health. However, the focus of the vast majority of these studies has been on the individual traits and attitudes affecting adherence. Still little is known on the role of the social and physical context in supporting or hindering diabetes self-management, particularly from a qualitative standpoint. To address these limitations, this paper presents the findings of a Photovoice study on a sample of 10 type 2 diabetic older adults living in a deprived neighbourhood of an Italian city. The findings reveal that the possibility to engage in diet, exercise and blood sugar monitoring seems to be more affected by physical and social elements of the respondents' environment than by the interviewees' beliefs and attitudes. Both environmental barriers and social isolation emerge as barriers to lifestyle changes and self-care activities related to blood sugar monitoring. The predominance of bonding social capital, the scant level of trust and the negative perception of local health services result in a low level of social cohesion, a limited circulation of health information on diabetes management and, consequently, in poor health outcomes.

Abstract
BACKGROUND Various studies have found that medication adherence is generally low among patients with asthma, and that the complexity of the regimen may be a potential factor. However, there is no information on the complexity of the regimen and its relationship to adherence and asthma outcomes in Ethiopian asthma patients. Therefore, this study assessed how complex medication regimens affected medication adherence and asthma control in patients with asthma. METHOD From February 1 to May 30, 2022, a multicenter cross-sectional study was conducted in three public referral hospitals in northwestern Ethiopia. The Medication Complexity Index (MRCI), a 65-item validated instrument, was used to represent the complexity of medication regimens The Medication Adherence Rating Scale for Asthma (MARS-A) was used to assess medication adherence, and the ACT was used to measure the level of asthma control. The association between predictor and outcome variables was determined using multivariable logistic regression analysis. P-values of < 0.05 were declared as a significant association. RESULT Patients with asthma (n = 396) who met the inclusion criteria were included in the final analysis. About 21.2% and 24.5% of the participants had high asthma-specific MRCI and patient-level MRCI, respectively. The majority (84.4%) of the participants did not adhere to their medication, and 71% of the participants were classified as having uncontrolled asthma. According to the result of the multivariable analysis, moving from a high asthma-specific MRCI to a moderate asthma MRCI enhances the likelihood of medication adherence by 2.51 times (AOR = 2.51, 95%CI: (1.27, 7.71). Likewise, patients who have low asthma MRCI were four times more likely to adhere to the medication compared with high asthma MRCI (AOR = 3.80, 95%CI: (2.0, 11.1). Similarly, patients having low patient-level MRCI were eight times more likely their asthma level had been controlled (AOR = 7.84, 95%CI: 1.46 to 21.3) and patients who had moderate patient-level MRCI were three times (AOR = 2.83, 95%CI: 1.05 to 8.25) more controlled asthma compared with patients who had high patient level MRCI. CONCLUSION The majority of asthma patients had low and moderate complexity of MRCI. Patients with low and moderate regimen complexity demonstrated high adherence and had well-controlled asthma. Therefore, future researchers should consider MRCI as one factor for adherence and asthma control levels.

Abstract
BACKGROUND The prevalence of type 2 diabetes mellitus has increased in the past decades. We investigated the prevalence of diabetes and its awareness, treatment, and control among adult residents of Tehran. METHODS We used the recruitment phase data of the Tehran Cohort study, enrolling a random sample of adult residents of Tehran aged ≥35 years. Diabetes was defined as self-report, current use of glucose-lowering medications, and/or fasting plasma glucose (FPG) ≥126mg/dl. Impaired fasting glucose (IFG) was defined as an FPG of 100-125mg/dl. Awareness was defined as diabetes self-report, treatment as receiving glucose-lowering medications, and glycemic control as FPG <126mg/dl. The age- and sex-weighted estimates were calculated using the 2016 national census. Logistic regression models were used to determine the factors associated with diabetes awareness, treatment, and control. RESULTS A total of 8151 participants were included. Age- and sex-weighted prevalence of diabetes mellitus and IFG were 16.7% (95% CI: 15.1-18.4) and 25.1% (95% CI: 23.1-27.1), respectively. Diabetes was more prevalent in the eastern and central districts of Tehran. Advanced age (OR per 1-year increase: 1.026, 95% CI: 1.021-1.030), male sex (OR: 1.716, 95% CI: 1.543-1.909), higher BMI levels (OR for BMI ≥35 vs. <20 kg/m2: 4.852, 95% CI: 3.365-6.998), pre-existing hypertension (OR: 1.552, 95% CI: 1.378-1.747), dyslipidemia (OR: 1.692, 95% CI: 1.521-1.883), and chronic kidney disease (OR: 1.650, 95% CI: 1.019-2.673) were associated with an increased odds of diabetes mellitus. On the contrary, diabetes mellitus was less likely in current tobacco (OR: 0.872, 95% CI: 0.765-0.994) and alcohol users (OR: 0.836, 95% CI: 0.703-0.994) compared to non-users. Among diabetic individuals, 82.8% were aware of their condition, 71.9% received treatment, and 31.7% of treated patients had adequate glycemic control. Advanced age and pre-existing comorbidities, including hypertension and dyslipidemia, were associated with higher diabetes awareness and treatment. Furthermore, advanced age, higher levels of education, and female sex were determinants of better glycemic control among treated diabetic participants. CONCLUSION There is a high prevalence of diabetes and IFG among adult residents of Tehran. Additionally, more than two-thirds of treated diabetics living in Tehran remain uncontrolled.

Abstract
Background
Medication nonadherence in patients with chronic diseases, particularly in type 2 diabetes mellitus (T2DM) with comorbidity, has continued to be the cause of treatment failure. The current study assessed medication adherence and its impact on glycemic control in T2DM patients with comorbidity.
Methods
An institutional-based multicenter cross-sectional study was conducted among T2DM patients with comorbidity at the selected hospitals in Northwest Ethiopia. Medication adherence was measured using a structured questionnaire of the General Medication Adherence Scale (GMAS). A logistic regression model was used to identify predictors of the level of medication adherence and glycemic control. P < 0.05 at 95% confidence interval (CI) was statistically significant.
Results
A total of 403 samples were included in the final study. This study showed that more than three-fourths (76.9%) of the participants were under a low level of medication adherence. Source of medication cost coverage [AOR = 10.593, 95% CI (2.628–41.835; P = 0.003], monthly income (P < 0.00), self-monitoring of blood glucose (SMBG) practice [AOR = 0.266, 95% CI (0.117–0.604); P = 0.002], number of medications [AOR = 0.068, 95% CI (0.004–0.813); P = 0.014] and medical conditions [AOR = 0.307, 95% CI (0.026–0.437); P = 0.018] were found to be significant predictors of medication adherence. Significantly, majority (74.7%) of participants had poor levels of glycemic control. Patients who had a high level of medication adherence [AOR = 0.003, 95% CI (0.000–0.113); P = 0.002] were found less likely to have poor glycemic control compared with patients who were low adherent to their medications.
Conclusion
The current study concluded that medication adherence was low and significantly associated with poor glycemic control. Number of medical conditions and medications were found to be associated with medication adherence. Management interventions of T2DM patients with comorbidity should focus on the improvement of medication adherence.

Abstract
Background: Diabetes mellitus is a chronic, progressive disorder that causes a variety of health problems. Adherence to medication is a major factor in the treatment outcome. The goal of this study is to translate and test the psychometric features of the Kurdish version of the Morisky Medication Adherence Scale (MMAS-8) among type 2 diabetic patients.
Methods: The research used a cross-sectional approach. The researchers looked at a convenient sample of diabetic Kurdish individuals. MMAS-8 was translated into Kurdish using a normal “forward–backward” technique. It was then tested on 307 type 2 diabetic outpatients in a convenience sample. Internal consistency was checked for reliability. Convergent and known group validity were used to confirm validity. For the authentic statistical analysis, the Statistical Package for Social Sciences (SPSS) version 20 was used.
Results: According to MMAS-8, 20 patients (6.5%) had a high adherence rate, 66 (21.5%) had a medium adherence rate, and 221 (72%) had a low adherence rate. There was no significant link between adherence score and gender (P = 0.055), illness duration (P = 0.251), or educational level (P = 0.12). There was a significant connection between adherence and HBA1C (P 0.001).
Conclusion: The results of this validation study show that the Kurdish version of the MMAS-8 is a reliable and valid measure of medication adherence that may now be used. non-adherent. Developing patients’ treatment adherence will improve treatment managements and control.

Abstract
Background Therapeutic observance remains a major problem in managing diabetic subjects, just like in other pathologies treated by medication and lifestyle modification. This study aims to determine the rate of therapeutic observance among diabetic subjects in the province of Essaouira and to identify the factors that influence it. Methods A cross-sectional questionnaire survey was conducted among 498 type 1 and 2 diabetic subjects, regularly being checked at different health centers in the province of Essaouira (Morocco). Results Almost a quarter of the surveyed subjects (23.3%) had poor observance. The results of the binary logistic regression model show that, in order of importance, observance is associated with six factors: Availability and access to medical treatment (Odds Ratio OR: 3; 95% CI confidence interval [1.78-5.03]); the side effects related to the treatment (OR: 2.60; 95% CI [1.65-4.09]); the family support (OR: 1.58 ; 95% CI [0.95-2.61]); duration of diabetes (OR: 0.55 ; 95% CI [0.34-0.88]); the age (OR: 0.50 ; 95% CI [0.30-0.82]); awareness level about the disease (OR: 0.43 ; 95% CI [0.21-0.90]). Conclusion The results of the present study have allowed us to identify several factors that can influence therapeutic observance, that prove necessary to be considered and acted upon.

Abstract
BACKGROUND Diabetes mellitus (DM) is a progressively increasing metabolic disorder and a significant public health burden that demands immediate global attention. However, there is a paucity of data about adherence to antidiabetic drugs among patients with type-2 (T2)DM in Uttarakhand, India. Outpatient research reported that more than 50% of patients do not adhere to the correct administration and appropriate medicine dosage. It has been reported that patients with chronic diseases who adhere to treatment may experience improvement in quality of life (QoL) and vice versa.
AIM To assess the adherence to antidiabetic medication and QoL among patients with T2DM.
METHODS This cross-sectional descriptive study was conducted at a tertiary care hospital in Uttarakhand, India. The Medication Adherence Rating Scale and World Health Organization QoL-BREF scale were used to assess medication adherence and QoL.
RESULTS Two hundred seventy-seven patients suffering from T2DM participated in the study. Their mean age was 50.80 (± 10.6) years, 155 (56%) had a poor adherence level and 122 (44%) had a good adherence level to antidiabetic medications. After adjusting for sociodemographic factors, multiple linear regression analysis found patients who were adherent to antidiabetic medications had significantly higher mean overall perception of QoL and overall perception of health, with beta scores of 0.36 and 0.34, respectively (both P = 0.000) points compared with nonadherent patients.
CONCLUSION There was an association between medication adherence and QoL in patients with T2DM. Hence, there is a need to plan awareness and counseling programs followed by regular follow-up to motivate patient adherence to recommended treatment and lifestyle regimens.

Abstract
This study aims to examine the mechanism of how supportive interaction and facilitator input variety in mutual aid groups impact treatment adherence of young people with chronic health conditions, with consideration of time effects, which have been rarely studied in the existing literature. A stratified random sample of 391 individuals aged 12–45 years with chronic health conditions were recruited from mutual aid groups in Hong Kong and completed both the baseline and 12-month follow-up surveys. The results of the structural equation modeling indicated that supportive interaction and facilitator input variety positively predicted treatment adherence in a delayed condition, whereas members’ treatment adherence in the baseline survey had reversed effects on members’ supportive interaction in the follow-up survey. The findings of this study shed light on the dynamic mechanism of the mutual aid groups and provide important implications to promote better rehabilitation outcomes of young people with chronic health conditions.

Abstract
Abstract. Background: Treatment adherence is associated with a number of personal characteristics (e.g., self-esteem, self-efficacy, locus of control) and illness perceptions. However, there is a lack of studies for Type 2 Diabetes Mellitus (T2DM). Aims: The aim of this study was to compare adherence behavior of British and Greek people with T2DM and examine the association between personal characteristics, illness perceptions, and adherence. Method: This was a cross-cultural, cross-sectional study. Five hundred eighty participants completed questionnaires, 208 males (35.9%) and 372 females (64.1%) with a mean age of 49 years. Regression analyses and t-tests were used. Results: Personal characteristics and illness perceptions predicted adherence and British patients reported better exercise adherence while Greek patients reported better diet and medication adherence; both groups reported suboptimal adherence. Self-efficacy, Health Locus of Control (HLoC), and illness perceptions were the main adherence determinants. Limitations: The use of self-reports and the convenience sampling method are the main limitations of this study. Conclusion: The findings address a significant gap in research and can inform future adherence-enhancing interventions to promote the well-being of people with T2DM.

Abstract
Background Adherence to oral antidiabetics plays a pivotal role in controlling diabetes. Healthcare workers evaluate this adherence when visited by patients. Objectives The primary objective of this study was to validate the existing LMAS-14 (Lebanese Medication Adherence Scale) in Lebanese diabetic adults. The secondary objective was to evaluate factors affecting adherence among this population. Setting The main five Lebanese governorates. Methods This study was conducted between May and September 2019, and community dwelling adult participants were enrolled using a proportionate random sample. The scale was validated using factor analysis and reliability testing, while bivariate and multivariable analyses assessed correlates of adherence. Main outcomes measures Validity of LMAS-14. Results A total of 308 participants were included, and the response rate was 91.25%. All LMAS-14 items converged over a solution of four factors, explaining a total of 64.39% of the variance (α = 0.859). The cutoff point between controlled and uncontrolled patients was set at 11. The sensitivity and specificity were good at this cutoff (71.1% and 94.74%, respectively). Results showed that 167 (57.2%) patients had good medication adherence. Advanced age (Beta = 0.046; p = 0.001) and having medical coverage (Beta = 1.452; p = 0.005) were significantly associated with higher adherence. Furthermore, adherence to oral antidiabetic drugs (Beta = 1.197; p = 0.018), female gender (Beta = 2.695; p = 0.011), and taking dyslipidemia medication (Beta = 3.527; p = 0.005) predicted higher diabetes control. Conclusion This study validated the LMAS among Lebanese adult diabetic patients taking oral antidiabetic drug. Advanced age and having medical coverage were associated with higher medication adherence. Further national studies are warranted to corroborate our findings.

Abstract
BACKGROUND Diabetes often coexists with other medical conditions and is a contributing cause of death in 88% of people who have it. The study aimed at evaluating medication adherence, self-care behaviours and diabetes knowledge among patients with type 2 diabetes mellitus in Ghana. METHODS A total of 330 participants were recruited into the study from three public hospitals in the Tamale metropolis. A validated medication adherence questionnaire and the Summary of Diabetes Self-care Activities tool were used to assess medication adherence and self-care activities respectively. Logistic and linear regressions were used to determine factors positively associated with non-adherence to medication and self-care behaviours respectively. RESULTS Of the 330 participants whose data were analysed, the mean (SD) age was 57.5 (11.8) years. The majority (84.5%) were adherent to anti-diabetes medication. Participant's age, educational level, and practice of self-care behaviours influenced adherence to anti-diabetes medication. Participants aged 70 years and above were 79% less likely to be non-adherent to medication as compared to those below 50 years [OR = 0.21 (95%CI: 0.06-0.74), p = 0.016]. Participants with senior high school education were 3.7 times more likely to be non-adherent to medication than those with tertiary education [OR = 3.68 (95%CI: 1.01-13.44), p = 0.049]. Participants with tertiary education had an increase in the level of practice of self-management by 1.14 (p = 0.041). A unit increase in knowledge score also increased the level of practice of self-management by 3.02 (p<0.001). CONCLUSION The majority of participants were adherent to anti-diabetes medication. Non-adherence to medication was associated with younger age and low level of education. Interventions to improve adherence should target younger and newly diagnosed patients through aggressive counselling to address healthy self-management behaviours.

Abstract
Background In the primary care setting in Macau, type 2 diabetes mellitus (T2DM) is the seventh most common reason for consultation. Inadequate glycaemic control constitutes a major public health problem and is associated with premature death and disability and decreased quality of life. Moreover, this condition substantially increases healthcare expenditures. Objective The primary objective was to assess the successful glycaemic control rates, blood pressure (BP) and cholesterol control rates in patients with T2DM in a Macau primary care setting. The secondary objective of this study was to assess the delay of insulin initiation in the Sao Lourence Health Center. Methods Patients were stratified according to age (<65 years vs ≥65 years) and sex. Successful glycaemic control was defined as glycated haemoglobin (HbA1c) <7%. Successful cholesterol control was defined as a low-density lipoprotein cholesterol (LDL-C) level <2.6 mmol/L, and BP control was defined as BP <140/90 mm Hg. Results Among the 2157 participants included in this study, 1046 (48.5%) patients had HbA1c <7%, 1209 (56.1%) patients had BP <140/90 mm Hg and 1244 (57.7%) patients had LDL-C <2.6 mmol/L. In conclusion, only 403 (18.7%) patients met the targets for all three measures. Of the 235 patients who were on insulin therapy, the mean (±SD) duration from T2DM diagnosis to insulin initiation was 7.47±6.52 years, the mean (±SD) duration from HbA1c not meeting the target (HbA1c ≥7% over 1 year and persistently) to insulin initiation was 3.34±3.66 years and the mean baseline HbA1c was 9.13%. Compared with patients with a longer duration (≥5 years) of HbA1c not meeting the target before insulin initiation, those who started insulin within 1 year of HbA1c not meeting the target had a better glycaemic control rate (40.7% vs 13%). Conclusions Nearly half of the patients at Sao Lourence Health Center, a primary care centre in Macau, met the glycaemic control target, but less than one-fifth of patients met all three targets for T2DM control. Moreover, there was a delay in insulin initiation for people with T2DM.

Abstract
Background: Since insulin became a focal point of diabetes management, several studies have been carried out to monitor and improve patient outcomes. Adherence insulin therapy is an important part of diabetes management. Aim: This study reviews the responses of patients being managed in a diabetic care setting in monitoring their adherence to basal bolus insulin therapy. Method: A pre-validated questionnaire containing 18 questions was administered to patients in the diabetic care unit of the Security Forces Hospital, Riyadh, Saudi Arabia. Results: The levels of adherence with basal bolus insulin therapy was 61.9%. There is no considerable difference in adherence levels of male and female respondents with 31.62% and 31.58% respectively. The younger age groups (14-29) had the highest adherence levels at 65.75%. Higher levels of patient literacy and the location also have a positive relationship with adherence. Conclusion: To improve adherence levels, dosing should be made with consideration for patient convenience, and patients should be encouraged to build positive psychological relationships. Further studies should look to studying outcomes of therapy, and markers should be developed to monitor patient progress on therapy regimen regularly. The aspect of short clinic visits is another major consideration that needs to be look into properly to understand and monitor patients’ proper adherence toward the basal bolus insulin.

Abstract
Abstract
Objective
To evaluate factors affecting adherence to oral antidiabetic treatment in the Lebanese population and to develop the Diabetes Medication Adherence Scale (DMAS) based on these factors.
Methods
A cross-sectional study was conducted on a sample of Lebanese diabetic patients. Data were collected using a structured questionnaire. The level of adherence was measured using the Lebanese Medication Adherence Scale (LMAS-14). Bivariate analyses and multivariable analysis was done using SPSS. Psychometric evaluation of DMAS included an assessment of internal consistency, factor analysis, evaluation of sensitivity and specificity. Criterion-related validity was assessed by comparison with LMAS-14 measure of adherence.
Key findings
A total of 500 patients were recruited. 39.2% were adherent to treatment. Long working hours, increased number of oral antidiabetic medication per day, drug discontinuation when travelling, longer duration of diabetes and treatment burden were among factors that decreased adherence. While understanding the treatment regimen, following up physician recommendations and following up the recommended diet contributed to good medication adherence. The final 7-item scale (DMAS) had a good internal consistency (Cronbach’s α = 0.612) and a good correlation and agreement with LMAS-14 (Spearman’s rho = 0.699, Cohen’s kappa = 0.566). Patients with high DMAS scores were significantly more likely to have controlled glycaemia (P < 0.05). Sensitivity and specificity reached 70.39% and 51.47%, respectively.
Conclusion
Adherence to oral antidiabetic treatment is suboptimal in Lebanon. The DMAS is a reliable instrument for assessing adherence and predicting poor glycaemic control in clinical practice, but requires further validation in other populations.

Abstract
Background: Patients with type-2 diabetes have poor adherence to the therapeutic regime. It can result in various complications in body systems associated with undesirable metabolic control. Purpose: The present study aimed to explore the inhibitors of medication adherence in patients with type-2 diabetes. Patients and methods: This was a qualitative study using a conventional content analysis method. Participants were 12 patients with type-2 diabetes referred to the diabetes unit in Saghez, Kurdistan Province in 2015. The purposive sampling method was used with a maximum variation in sampling, and data collection was continued until data saturation was achieved. Semi-structured interviews were used for data collection. Interviews were recorded and immediately transcribed verbatim. Results: Data analysis led to the development of four main categories including disbelief in medical explanatory/prescriptive knowledge, lived experiences of the disease, challenges of everyday life, and interactive/economic challenges. The main inhibitors were the patient's understanding of his/her own physical status and strategies used for maintaining the internal balance. Healthcare providers need to take patients' perceptions into account when they are prescribing medicinal diets. Another inhibitor was the incidents of everyday life, including economic and social challenges, and interactions to receive education and skills for living with the disease. Conclusion: Beliefs of the medical team and patients should be brought closer to each other, and patients' trust in the medical team should be increased. Nurses should consider the unique experience of every patient when giving healthcare recommendations, and try to limit the existing challenges as much as possible.

Abstract
BACKGROUND Different studies reported that higher diabetes-specific Medication Regimen Complexity Index (MRCI) has a negative impact on glycemic control potentially by decreasing medication adherence. However, information about regimen complexity and its association with adherence and glycemic control in Ethiopian patients with diabetes is unknown. AIM To evaluate medication regimen complexity and to assess its impact on medication adherence and glycemic control among patients with type 2 diabetes Mellitus (T2DM). METHODS A hospital-based cross-sectional design was conducted at Debre Tabor General Hospital from 1 May 2018 to 30 June 2018. Medication regimen complexity was evaluated using the 65-item validated tool called Medication Complexity Index (MRCI). Adherence was measured using Morisky Medication Adherence Scale while patients were classified as having poor or good glycemic control based on the recent record of their fasting blood glucose. Multivariable logistic regression analysis was applied to determine the association between predictive variables and outcome variables. RESULTS A total of 275 patients with T2DM who meet the inclusion criteria were included in the final analysis. About 22.2% of the participants were classified as having high diabetes-specific MRCI, whereas 35.6% of the participants were classified as having high patient-level MRCI. The majority (70.5%) of the respondents were adherent to their medications, and 42.9% of the total population were categorized as having good glycemic control. According to the result of the multivariate analysis, patients with low-level and moderate-level MRCI of both diabetes-specific and patient-level MRCI were more adherent to their medication compared with patients with high MRCI. High diabetes medication regimen complexity was associated with poor glycemic control in the adjusted analyses (adjusted OR = 0.276; 95% CI = 0.100 o 0.759). CONCLUSION The prevalence of high MRCImedication regimen complexity index is high among patients with T2DM. Patients with low and moderate regimen complexity had improved adherence. High diabetes-specific medication regimen complexity was associated with poor glycemic control. Simplification of a complex medication regimen for patients with diabetes should be sought by physicians and pharmacists to improve medication adherence and subsequent improvement in glycemic control.

Abstract
BACKGROUND The prevalence of type 2 diabetes mellitus (T2DM) is increasing at an alarming rate in developing countries. The accompanying complications of T2DM can be reduced by maintaining a good adherence to medication and self-care activities. OBJECTIVES To evaluate medication adherence and self-care behaviors among patients with T2DM. METHODS A total of 497 subjects with T2DM were recruited from three hospitals and a government clinic in the state of Selangor, Malaysia. Previously validated scales were used to measure medication adherence (Morisky Medication Adherence Scale) and diabetes self-care activities (Summary of Diabetes Self-Care Activities). Pearson correlation coefficient was used to investigate the relationship between the risk factors and medication adherence. Pearson χ2 test of association was used to test significant association. RESULTS The mean age of the subjects was 55.5 years. The mean Morisky Medication Adherence Scale score was 5.65 ± 1.97, indicating a moderate adherence level to medication. Among the subjects who had low adherence level, 50.9% were Malays, followed by 34.2% Indians. The Pearson χ2 test of association indicated a significant association (P = 0.000) between ethnicity and medication adherence. The subjects had better self-care behaviors in their general diet (mean 5.04 ± 1.88) and poor self-care behaviors in blood sugar testing (mean 2.13 ± 2.34). CONCLUSIONS The Malaysians had a moderate medication adherence level, whereas they were nonadherent to blood glucose testing. Emphasis on self-care activities and medication adherence is relevant to improve outcomes in the management of T2DM.

Abstract
OBJECTIVE To compare the glycaemic control and cardiovascular risk factor profiles of younger and older patients with type 2 diabetes. Cross-sectional analysis of data from the 2015 Australian National Diabetes Audit was undertaken. METHODS Data were obtained from adults with type 2 diabetes presenting to Australian secondary/tertiary diabetes centres. Logistic regression examined associations with glycated haemoglobin A1c (HbA1c) >7% (53 mmol/mol) and cardiovascular risk factors. RESULTS Data from 3492 patients were analysed. Mean (±SD) age was 62.9±12.5 years, mean diabetes duration 13.5±9.4 years and mean HbA1c 8.2%±1.8%. Mean HbA1c was 8.6%±2.1% and 8.0%±1.6% for the younger (<60 years) and older subgroups (≥60 years), respectively (p<0.001). The adjusted OR (aOR) of HbA1c above >7.0% was 1.5 times higher (95% CI 1.22 to 1.84) for younger patients compared with older patients after adjustment for gender, smoking, diabetes duration, renal function and body mass index. Younger patients were also more likely to have dyslipidaemia (aOR 2.02, 95% CI 1.53 to 2.68; p<0.001), be obese (aOR 1.25, 95% CI 1.05 to 1.49; p<0.001) and be current smokers (aOR 2.13 95% CI 1.64 to 2.77; p<0.001) than older patients. CONCLUSIONS Younger age was associated with poorer glycaemic control and adverse cardiovascular risk factor profiles. It is imperative to optimise and monitor treatment in order to improve long-term outcomes.

Abstract
INTRODUCTION Longer medication persistence in type 2 diabetes (T2D) is associated with improved glycaemic control. It is not clear which oral therapies have the best persistence. The objective of this study was to compare medication persistence across different oral therapies in people with T2D. METHODS We performed a retrospective cohort analysis using a primary-care-based population, the Royal College of General Practitioners Research and Surveillance Centre cohort. We identified new prescriptions for oral diabetes medication in people with type 2 diabetes between January 1, 2004 and July 31, 2015. We compared median persistence across each class. We also compared non-persistence (defined as a prescription gap of ≥ 90 days) between classes, adjusting for confounders, using Cox regression. Confounders included: age, gender, ethnicity, socioeconomic status, alcohol use, smoking status, glycaemic control, diabetes duration, diabetes complications, comorbidities, and number of previous and concurrent diabetes medications. RESULTS We identified 60,327 adults with T2D. The majority 42,810 (70.9%) of those had one or more oral medications prescribed; we measured persistence in those patients (who were prescribed 55,728 oral medications in total). Metformin had the longest median persistence (3.04 years; 95% CI 2.94-3.12). The adjusted hazard ratios for non-persistence compared with metformin were: sulfonylureas HR 1.20 (1.16-1.24), DPP-4 inhibitors HR 1.43 (1.38-1.49), thiazolidinediones HR 1.71 (95% CI 1.64-1.77), SGLT2 inhibitors HR 1.04 (0.93-1.17), meglitinides HR 2.25 (1.97-2.58), and alpha-glucosidase inhibitors HR 2.45 (1.98-3.02). The analysis of SGLT2 inhibitors was limited by the short duration of follow-up for this new class. Other factors associated with reduced medication persistence were female gender, younger age, and non-white ethnicity. CONCLUSIONS Persistence is strongly influenced by medication class and should be considered when initiating treatments.

Abstract
BACKGROUND Life expectancy of patients with transfusion-dependent thalassemias has increased with the development of improved treatment over the last few decades. However, β-thalassemia disorder still has considerable lifetime treatment demands and heightened risk of frequent complications due to transfusion-transmitted infections and iron overload, which may affect thalassemic patients' functioning in different domains. OBJECTIVES The vast majority of published studies on thalassemic patients have focused on children and adolescent functioning, and little research has examined adults. Hence, the current study was planned to examine the functioning and resilience of adult thalassemic patients in a comprehensive way. METHODS We examined multidimensional resilience and functioning across different domains (psychological adjustment, treatment adherence, social functioning and occupational functioning). We also examined demographic and medical variables that may relate to resilience and functioning. Participants were adult patients [n = 38; age M = 31·63, standard deviation (SD) = 7·72; 72% female] with transfusion-dependent thalassemia in treatment in a hospital in the northeastern United States. RESULTS The results suggest that most adult thalassemic patients tend to be resilient, demonstrating good functioning in four main domains: psychological adjustment, treatment adherence, social functioning and occupational functioning. CONCLUSION Despite the considerable demands of their illness, adult thalassemic patients appeared to be adapting well, demonstrating evidence of multidimensional resilience.

Abstract
INTRODUCTION Treatment options for type 2 diabetes are becoming increasingly complex with people often prescribed multiple medications, and may include both oral and injectable therapies. There is ongoing debate about which drug classes provide the optimum second-line and third-line treatment options. In the real world, patient adherence and persistence determines medication effectiveness. A better understanding of adherence may help inform the choice of second-line and third-line drug classes. METHODS AND ANALYSIS This systematic review will compare adherence and persistence rates across the different classes of medication available to people with type 2 diabetes. It will include all identified studies comparing medication adherence or persistence between two or more glucose-lowering medications in people with type 2 diabetes. Research databases (MEDLINE, EMBASE, The Cochrane Library, The Register of Controlled Trials, PsychINFO and CINAHL) will be searched for relevant articles, using a comprehensive search strategy. All identified medication trials and observational studies will be included which compare adherence or persistence across classes of diabetes medication. The characteristics and outcomes of all the included studies will be reported along with a study quality grade, assessed using the Cochrane Risk Assessment Tool. The quality of adjustment for confounders of adherence or persistence will be reported for each study. Where multiple (n ≥ 3) studies provide compare adherence or persistence across the same 2 medication classes, a meta-analysis will be performed. ETHICS AND DISSEMINATION No ethics approval is required. This review and meta-analysis (where possible) will provide important information on the relative patient adherence and persistence, with the different classes of diabetes therapies. Once complete, the results will be made available by peer-reviewed publication. TRIAL REGISTRATION NUMBER CRD42015027865.

Abstract
OBJECTIVES The purpose of this study was to evaluate the impact of antidiabetic medication adherence on hospital utilization in patients with newly diagnosed type 2 diabetes mellitus (T2D). This study specifically analyzed patients with newly diagnosed T2D with the intent of lessening intragroup disease severity differences, and adjusting for a range of other clinical and demographic characteristics. METHODS This retrospective US claims database study evaluated adults with newly diagnosed T2D who started antidiabetic medications in 2005-2009, had ≥ 2 antidiabetic medication claims after their first (baseline). Medication adherence was evaluated using the medication possession ratio (MPR) of any or all antidiabetic medication(s) during the 3-year post-baseline period. Repeated-measures analyses examined changes in inpatient utilization from the pre- to post-baseline period. The impact of adherence on hospital utilization during the post-baseline period was evaluated with a logistic regression model to adjust for confounding factors. RESULTS The study included 192,717 patients (mean age, 55.0 years). Mean MPR for antidiabetic therapy was 0.74. MPR was highest in elderly patients and Medicare beneficiaries. Mean annualized inpatient admissions during the 3-year post-baseline period were significantly lower in patients with MPR ≥ 0.80 (1.4) than in those with MPR < 0.80 (2.2; P < 0.05). Logistic regression analysis, adjusting for patient characteristics and prior inpatient utilization, showed 39% lower odds of hospitalization (OR = 0.61; 95% CI = 0.534-0.693) for patients with MPR ≥ 0.80. People with T2D-related complications or hospitalization had approximately 2- to 3-fold higher risk of subsequent hospitalization. CONCLUSIONS In newly diagnosed T2D patients with antidiabetic therapy in the first three ensuing years, higher antidiabetic medication adherence was significantly associated with lower hospital inpatient utilization before and after adjusting for patient characteristics.

Abstract
Background Type D personality and medication nonadherence have been shown to be associated with poor health outcomes. Type D personality is associated with poor medication adherence in patients with coronary artery disease, myocardial infarction, and heart failure. However, the relationship between type D personality and medication adherence in patients with Type 2 Diabetes Mellitus (T2DM) remains unknown. This study aims to examine whether type D personality was associated with medication adherence in patients with T2DM. Design and Settings A follow-up study was conducted in general hospital of the People's Liberation Army in Beijing. Methods 412 T2DM patients (205 females), who were recruited by circular systematic random sampling, provided demographic and baseline data about medical information and completed measures of Type D personality. Then, 330 patients went on to complete a self-report measure of medication adherence at the sixth month after baseline data collection. Chi-square test, t tests, and hierarchical multiple regression analyses were conducted, as needed. Results Patients with type D personality were significantly more likely to have poor medication adherence (p<0.001). Type D personality predicts poor medication adherence before and after controlling for covariates when it was analyzed as a categorical variable. However, the dimensional construct of type D personality was not associated with medication adherence when analyzed as a continuous variable. Conclusion Although, as a dimensional construct, type D personality may not reflect the components of the personality associated with poor medication adherence in patients with T2DM, screening for type D personality may help to identify those who are at higher risk of poor medication adherence. Interventions, aiming to improve medication adherence, should be launched for these high-risk patients.

Abstract
BACKGROUND The control of diabetes mellitus depends on several factors that also include individual lifestyles. We assessed glycaemic control status and self-management behaviours that may influence glycaemic control among diabetic outpatients. METHODS This cross-sectional study among 198 consenting randomly selected patients was conducted at the University Teaching Hospital diabetic clinic between September and December 2013 in Lusaka, Zambia. A structured interview schedule was used to collect data on demographic characteristics, self-management behaviours, and laboratory measurements. Binary logistic regression analysis using IBM SPSS for Windows version 20.0 was carried out to predict behaviours that were associated with glycaemic control status. RESULTS The proportion of patients that had good glycaemic control status (HbA1c≤ 48 mmol/mol) was 38.7% compared to 61.3% that had poor glycaemic control status (HbA1c≥ 49 mmol/mol). Adherence to antidiabetic treatment and fasting plasma glucose predicted glycaemic control status of the patients. However, self-blood glucose monitoring, self-blood glucose monitoring means and exercise did not predict glycaemic control status of the patients. CONCLUSION We find evidence of poor glycaemic control status among most diabetic patients suggesting that health promotion messages need to take into account both individual and community factors to promote behaviours likely to reduce nonadherence.

Abstract
AIMS Strict long term glucose, cholesterol and blood pressure control is advocated in type 2 Diabetes Mellitus (T2DM) patients. It is not known whether combined partial goals' achievement affects development of chronic complications. METHODS We evaluated the relative ability or failure of 5369 T2DM ambulatory patients to achieve and maintain control of blood pressure, glycaemia and cholesterol for 3 consecutive years. Correlation between the extent of combined goal achievement, and development of chronic complications was determined. RESULTS Only 9 patients (0.17%) fully achieved and none completely failed to achieve all strict goals. Therefore, patients were characterized as either partial achievers (PA) (n=699) or partial non achievers (PNA) (n=322). As compared to PA patients, PNA patients were significantly younger, single, and demonstrated a higher female and Arab ethnicity dominance. PNA patients had higher BMI, received more insulin treatment and consumed more hospital services. The incidence of microvascular complications during 3 years was significantly increased in PNA patients. CONCLUSIONS A negligible number of primary care patients completely and persistently achieve or fail to achieve combined control of major diabetes targets. Partial achievement of these targets correlates with specific patients' characteristics and incidence of chronic micro-vascular complications.

Abstract
BACKGROUND Lack of adherence to anti diabetic medication causes suboptimal blood sugar control among patients with diabetes and can lead to treatment failures, accelerated development of complications and increased mortality. This study assessed factors associated with adherence to anti diabetic medication in rural eastern Uganda. METHODS A cross sectional study was conducted among 521 patients with diabetes in Iganga and Bugiri hospitals between October 2012 and January 2013. Respondents were patients who were18 years and above and had been on diabetic treatment for not less than a month. Pretested questionnaires were used. Variables that were collected included socio-demographic characteristics, possible barriers to adherence, and self management efforts. Adherence was assessed using self reports. Descriptive and inferential statistics were done to determine adherence to anti diabetic medication and the associated factors. RESULTS The level of adherence to anti diabetic medication was 83.3% and factors that were independently associated with adherence were; having been on anti diabetic drugs for at least three years (OR = 1.89, 95% CI = 1.11 - 3.22), availability of diabetic drugs (OR = 2.59, 95% CI = 1.54 - 3.70), and having ever had diabetic health education (OR = 4.24, 95% CI =1.15 - 15.60). CONCLUSION About four in five patients adhere to anti-diabetic treatment. Strategies aimed at improving anti diabetic drug availability and providing health education could improve adherence.

Abstract
BACKGROUND Adherence to medications is an important factor that contributes to therapeutic success. With the current increase in the elderly population, information relating to adherence to treatment and quality of life (QoL) of diabetic elderly patients will help the healthcare provider to improve their treatment. Thus, this study aims to determine the factors affecting adherence to medications and the consequence of non adherence to QoL. MATERIALS AND METHODS This was a cross-sectional study using validated Morisky Medication Adherence Scale (MMAS) Questionnaire. This study was conducted to assess the level of adherence on oral hypoglycemic medications (OHM) and quality of life of the Type 2 diabetes mellitus (T2DM) elderly patients in an urban health centre in Malaysia. A retrospective medication record review was also conducted to collect and confirm data on patients' demographics, diagnosis, treatments, and outcomes. RESULTS One hundred and seventy nine patients were recruited in this study. Median adherence score was 7.75 (IQR 6.50- 8.00). Good adherer was observed in 48.00% of the participants. A Chi-square test indicated significant correlation between adherence and HbA1c (p= 0.010). The mean elderly diabetes mellitus Problem Areas in Diabetes (PAID) score was 6.30 ±SD 8.50. A significant inversed association was observed between PAID score and the level of adherence (r = - 0.175, p< 0.05). A highly significant difference in the low adherence group (p = 0.002). PAID score significantly correlated with age (years), female gender and HbA1c (p <0.05). A negative association between HbA1c levels and adherence was identified where a 1% increase in HbA1c was associated with a 30% decrease in the likelihood of being adherent. CONCLUSION A medication adherence rate of 48% was obtained among elderly T2DM patients treated in the primary care clinic. This study showed that HbA1c is a relevant tool to assess patient glycemic control and adherence. Sociodemographic characteristics were not statistically significantly associated with adherence. We reported a negative correlation between adherence and T2DM related emotional distress. The identified factors that relieve emotional distress of the elderly T2DM patients are similar with the western countries.

Abstract
Adherence with oral hypoglycaemic agent is crucial to achieve optimal glycaemic control. The 8-item Morisky Medication Adherence Scale (MMAS-8) has been frequently used, yet the association between MMAS-8 score and glycaemic control among Chinese diabetes patients is largely unknown. Two general out-patient clinics were randomly selected in a district with socio-demographic characteristics representative of the entire Hong Kong population. A consecutive sample of adult type-2 diabetes patients currently taking oral hypoglycaemic agents was included. The glycaemic control was reflected by the level of hemoglobin A1c (HbA1c) taken within the previous 6 months. Factors associated with poor glycaemic control (HbA1c ≥ 7.0%) were evaluated by linear regression analysis. From 565 eligible Chinese patients with an average age of 63.2 years (SD 9.7) and male proportion of 46.5%, the average HbA1c was 7.1% (SD 1.1%), and 52.0% had poor glycaemic control. The proportion of poor medication adherence (MMAS-8 ≤ 6) was 32.2%. After controlling for socio-demographics, lifestyle, medication use, and health characteristics, the MMAS-8 score was correlated with better glycaemic control (beta -0.095; 95%CI -0.164 to -0.026, P = .007). The MMAS-8 score had a weak and negative correlation with HbA1c level. The instrument should be applied with caution when predicting glycaemic control in clinical practice.

Abstract
BACKGROUND Medication nonadherence is known to worsen glycemic control. Few studies have examined this relationship over several years. OBJECTIVE The aim of this study was to examine the longitudinal effect of medication nonadherence on glycemic control among a large cohort of veterans. METHODS Analysis was performed on a cohort of 11 272 veterans with type 2 diabetes followed from April 1994 to May 2006. The primary outcome measures were mean glycosylated hemoglobin A1c (A1C) and proportion in poor control (A1C > 8%) over time. The main predictor was medication nonadherence based on medication possession ratio (MPR). Other covariates included sociodemographics and ICD-9 coded medical and psychiatric comorbidities. Generalized linear mixed models (GLMMs) were used to assess the relationship between MPR and A1C after adjusting for covariates. RESULTS Mean follow-up was 5.4 years. In the linear mixed model, after adjusting for baseline A1C and other confounding variables, mean A1C decreased by 0.24 (P < 0.001) for each 10% increase in MPR (95% CI = -0.27, -0.21). In the fully adjusted GLMM, each percentage increase in MPR was associated with a 48% lower likelihood of having poor glycemic control (odds ratio = 0.52; 95% CI = 0.4, 0.6). In both continuous and dichotomized A1C analyses, average A1C showed a decreasing trend over the study period (P < 0.001). CONCLUSIONS In patients with type 2 diabetes, glycemic control worsens over time in the presence of medication nonadherence. Future studies need to take into account the complexity of patient- and system-level factors affecting long-term medication adherence to improve diabetes-related outcomes.

Abstract
Diabetic foot ulcers constitute a tremendous challenge for patients, caregivers, and health care systems. The high incidence and high financial costs associated with their treatment have transformed them in a health and economic worldwide problem. The increase in population life expectancy and lifestyle changes have facilitated the spreading of diabetes, rising diabetic foot ulcer incidence. Only 60%-80% of the patients achieve healing of ulcers, and the incidence of a second ulcer, in the same or different site of the foot that has had a previous ulcer, is approximately 50% in 2-5 years. In addition, ulcers with duration longer than 4 weeks are commonly associated with bad results in healing and an increased risk of amputation. Three patients with type 2 diabetes mellitus have been subjected to treatment with NL.1.2, a low-cost, biocompatible solid device that presented pro-angiogenic properties. The selected patients had undergone amputation, and their wounds, classified as Wagner II, did not show a significant progress in healing after a period of 2-5 months before treatment with NL.1.2. Complete closure of their wounds was achieved in 42-60 days.

Abstract
AIMS/INTRODUCTION The aim of the present study was to determine the status of glycemic control and identify factors associated with good glycemic control among diabetic patients treated at primary health clinics. MATERIALS AND METHODS A systematic random sample of 557 patients was selected from seven clinics in the Hulu Langat District. Data were collected from patients' medication records, glycemic control tests and structured questionnaires. Logistic regression analysis was carried out to predict factors associated with good glycemic control. RESULTS Variables associated with good glycemic control included age (odds ratio 1.033; 95% confidence interval 1.008-1.059) and duration of diabetes mellitus (odds ratio 0.948; 95% confidence interval 0.909-0.989). Compared with the patients who were receiving a combination of insulin and oral antidiabetics, those receiving monotherapy (odds ratio 4.797; 95% confidence interval 1.992-11.552) and a combination of oral antidiabetics (odds ratio 2.334; 95% confidence interval 1.018-5.353) were more likely to have good glycemic control. In the present study, the proportion of patients with good glycemic control was lower than that in other published studies. Older patients with a shorter duration of diabetes who were receiving monotherapy showed better glycemic control. CONCLUSIONS Although self-management behavior did not appear to influence glycemic control, diabetic patients should be consistently advised to restrict sugar intake, exercise, stop smoking and adhere to medication instructions. Greater effort by healthcare providers in the primary health clinics is warranted to help a greater number of patients achieve good glycemic control.

Abstract
PURPOSE Diabetes mellitus is a growing global health problem that affects patients of all ages. Even though diabetes mellitus is recognized as a major chronic illness, adherence to antidiabetic medicines has often been found to be unsatisfactory. This study was conducted to assess adherence to medications and to identify factors that are associated with nonadherence in type 2 diabetes mellitus (T2DM) patients at Primary Health Clinics of the Ministry of Health in Malaysia. MATERIALS AND METHODS The cross-sectional survey was carried out among T2DM patients to assess adherence to medication in primary health clinics. Adherence was measured by using the Medication Compliance Questionnaire that consists of a total of seven questions. Other data, such as patient demographics, treatment, outcome, and comorbidities were also collected from patient medical records. RESULTS A total of 557 patients were recruited in the study. Approximately 53% of patients in the study population were nonadherent. Logistic regression analysis was performed to predict the factors associated with nonadherence. Variables associated with nonadherence were age, odds ratio 0.967 (95% confidence interval [CI]: 0.948-0.986); medication knowledge, odds ratio 0.965 (95% CI: 0.946-0.984); and comorbidities, odds ratio 1.781 (95% CI: 1.064-2.981). CONCLUSION Adherence to medication in T2DM patients in the primary health clinics was found to be poor. This is a cause of concern, because nonadherence could lead to a worsening of disease. Improving medication knowledge by paying particular attention to different age groups and patients with comorbidities could help improve adherence.

Abstract
Background: The purpose of this study was to develop and validate a scale to measure the level of self-care behavior “doer identity” in persons with diabetes. Methods: Persons with diabetes (N = 355) completed questionnaires assessing self-as-doer identity and other related constructs. Principle components and parallel analyses and tests of reliability and validity were performed. Results: A 7 factor solution explained 55.24% of the total variance on behaviors. Cronbach’s alpha was .93 for the overall scale. Extracted components moderately correlated with one another and theoretically similar constructs. Self-as-doer identity significantly predicted all self-care behaviors (except for blood glucose monitoring) and glycemic control over and above related variables for persons with type 1 diabetes. Self-as-doer identity also predicted diet behaviors for persons with type 2 diabetes. Conclusions: Evidence for a reliable and valid factor structure of the Self-as-doer-Diabetes measure was demonstrated.

Abstract
AIMS Our main aim was to analyse gender differences in the association of adherence and poor glycaemic control (PGC) in a cohort of patients with type 2 diabetes mellitus in Germany. METHODS Baseline data of the DIANA-study, a prospective cohort study of type 2 diabetes mellitus patients in South-West Germany, were analysed. Information on medication adherence and factors related to PGC was obtained by self-administered questionnaire. PGC was defined as HbA(1c)≥7.5%. Bivariate and multivariate analyses using log-binomial regression were employed to assess overall and gender-specific associations of non-adherence and PGC. RESULTS 624 men and 518 women were included in the analyses. In total, 147 men (24%) and 114 women (23%) reported non-adherence to medication. In men, PGC was found in 37% of the participants reporting non-adherence and in 19% reporting adherence (adjusted prevalence ratio (PR)=1.90, 95%-CI: 1.46-2.49). In women, PGC was found in 19% of the participants reporting non-adherence and in 18% reporting adherence (adjusted PR=0.97, 95%-CI: 0.65-1.46). CONCLUSIONS Our results show gender-specific differences in the association of adherence and PGC. This underlines the need for efforts to improve glycaemic control in patients with type 2 diabetes mellitus with a particular focus on men.

Abstract
AIMS To analyse predictors of glycaemic control including medication adherence and body mass index (BMI) in UK general practice patients with sub-optimally controlled type 2 diabetes. METHODS Baseline demographic, health- and treatment-related measures were evaluated as predictors of one year glycaemic control defined separately as HbA(1c)≤ 7.5% and a continuous measure of HbA(1c) concentration, using multivariate regression models. Significant predictors were adjusted for objectively assessed medication adherence and BMI. RESULTS One-year HbA(1c) concentration was associated with baseline HbA(1c) (p<0.001), BMI (p=0.02), and inversely associated with age (p=0.007) and objectively assessed adherence. Adherent patients had one-year (adjusted) HbA(1c) concentration 0.65% (95% CI -1.04, -0.25; p=0.001) lower than nonadherent. Odds ratios (95% CI) of HbA(1c)≤ 7.5% for 10-year higher age were 1.63 (1.08, 2.45); for adherent compared to non-adherent patients 1.89 (0.84, 4.25); for patients receiving >5 compared to ≤ 5 medications 0.32 (0.13, 0.76); and for each 1% increment in baseline HbA(1c) 0.48 (0.31, 0.73). CONCLUSIONS The lower HbA(1c) achieved from greater adherence to glucose lowering treatment is comparable to that achieved with additional medication. Relationships between older age and better glycaemic control are not explained by better adherence, but may partly relate to lower BMI.

Abstract
BACKGROUND The need for an approach to measuring health results that incorporates patients' and payers' perspectives has generated a wide range of health care outcomes (HCOs), but it is yet unknown whether these HCOs are appropriate or valid for the health care decision-making process. OBJECTIVE The goal of this study was to assess HCOs, patient-reported outcomes (PROs), and economic outcomes in terms of validity and appropriateness to health care decision making in type 2 diabetes mellitus (T2DM). METHODS This systematic review of studies published between January 1, 1996, and November 1, 2010, comprised an electronic literature search of MEDLINE and Centre for Reviews and Dissemination databases. Studies included were clinical trials, observational studies, economic analyses, and studies on the development and validation of HCOs in T2DM in the adult population. HCOs were assessed and classified according to their relevance for decision makers in terms of feasibility for routine use, validity, sensitivity, reliability, understanding, and scope. RESULTS Two independent reviewers screened 4497 citations. Of these, 281 potentially eligible full articles were retrieved, and 185 met the inclusion criteria. A total of 121 HCOs in T2DM were identified: 80 (66.1%) PROs and 41 (33.9%) economic outcomes. Only 44.6% of the outcomes assessed were appropriate and valid for health care decision making. Greater deficiencies in evidence were found for PROs (61.3%), followed by economic outcomes (43.9%). CONCLUSIONS A large number of HCOs are being used in the health care decision-making process, but a significant proportion of these new outcomes have not been properly validated. Despite the fact that appropriate measures will depend on the specific needs of the decision makers, researchers need to use HCOs for which evidence of quality and appropriateness is available.

Abstract
BACKGROUND Most of interventions that have attempted to improve medication adherence in type 2 diabetes have been educational; on the assumption that knowledge regarding diabetes might affect patients' adherence to their treatment regimen. OBJECTIVES The purpose of the study was to investigate any association of knowledge and medication adherence with glycemic control in patients with type 2 diabetes mellitus. Setting The study was conducted at the Diabetes Outpatients Clinic, Hospital Pulau Penang. METHODS A cross-sectional study was conducted with a convenience sample of 540 adult patients with type 2 diabetes attending the clinic. A questionnaire including previously validated Michigan Diabetes Knowledge Test and Morisky Medication Adherence Scale was used and the patients' medical records were reviewed for haemoglobin A1C (HbA1C) levels and other disease-related information. A total of 35 (6.48%) patients were excluded after data collection due to lack of HbA1C results. RESULTS Five hundred and five patients were included in the final analysis, with a mean age of 58.15 years (SD = 9.16), 50.7% males and median HbA1C of 7.6 (IQR was 6.7-8.9). The median total knowledge score was 7.0 (IQR was 5.0-10.0) while the median adherence score was 6.5 (IQR was 4.75-7.75). Significant correlations were found between the three variables (HbA1C, knowledge and adherence). A significantly higher score for knowledge and adherence (P < 0.05) was found in those patients with lower HbA1C. Higher diabetes knowledge, higher medication adherence and using mono-therapy were significant predictors of good glycemic control in the multivariate analysis. CONCLUSION Patients' knowledge about diabetes is associated with better medication adherence and better glycemic control. In addition to other factors affecting medication adherence and glycemic control, healthcare providers should pay attention to knowledge about diabetes that the patients carry towards medication adherence.

Abstract
BACKGROUND The effectiveness of anti-vectorial malaria protective measures in travellers and expatriates is hampered by incorrect compliance. The objective of the present study was to identify the determinants of compliance with anti-vectorial protective measures (AVPMs) in this population that is particularly at risk because of their lack of immunity. METHODS Compliance with wearing long clothing, sleeping under insecticide-impregnated bed nets (IIBNs) and using insect repellent was estimated and analysed by questionnaires administered to 2,205 French military travellers from 20 groups before and after short-term missions (approximately four months) in six tropical African countries (Senegal, Ivory Coast, Chad, Central African Republic, Gabon and Djibouti). For each AVPM, the association of "correct compliance" with individual and collective variables was investigated using random-effect mixed logistic regression models to take into account the clustered design of the study. RESULTS The correct compliance rates were 48.6%, 50.6% and 18.5% for wearing long clothing, sleeping under bed nets and using repellents, respectively. Depending on the AVPM, correct compliance was significantly associated with the following factors: country, older than 24 years of age, management responsibilities, the perception of a personal malaria risk greater than that of other travellers, the occurrence of life events, early bedtime (i.e., before midnight), the type of stay (field operation compared to training), the absence of medical history of malaria, the absence of previous travel in malaria-endemic areas and the absence of tobacco consumption.There was no competition between compliance with the different AVPMs or between compliance with any AVPM and malaria chemoprophylaxis. CONCLUSION Interventions aimed at improving compliance with AVPMs should target young people without management responsibilities who are scheduled for non-operational activities in countries with high risk of clinical malaria. Weak associations between compliance and history of clinical malaria or variables that pertain to threat perception suggest that cognition-based interventions referencing a "bad experience" with clinical malaria could have only a slight impact on the improvement of compliance. Further studies should focus on the cognitive and behavioural predictors of compliance with AVPMs.

Abstract
BACKGROUND AND OBJECTIVE The promotion of therapeutic adherence is considered as an integral component of pharmaceutical care practice and patient healthcare. It has been shown that despite effective methods of treatment, 50% of diabetic patients fail to achieve satisfactory glycemic control, which leads to accelerated development of complications and increased mortality. Clinical experience indicates that no improvement of metabolic control is possible without patients' adherence to medications. This study sought to examine the rate of medication adherence and different factors affecting it among Type 2 diabetic patients in Egypt. METHODS A total of 226 Type 2 diabetic patients who fulfilled the inclusion criteria were recruited in the current study. Adherence to the treatment was evaluated during patients' hospitalization in the Outpatient Clinics of Internal Medicine Department at University of Mansoura, Egypt. The medication adherence has been assessed during a personal interview with each patient using a multiple-choice graded questionnaire. RESULTS In the study population, the adherence rates to medication, dietary/exercise and appointment were observed to be suboptimal. The most important social factors that were significantly affecting adherence rate to the prescribed oral hypoglycemic agent(s) included marital status (P < 0.01), family support (P < 0.01), and socio-economical level (P < 0.01). Other patient factors that were significantly affecting therapeutic adherence were patient knowledge about the disease (P < 0.01), patients' beliefs and motivation about prescribed drugs (P < 0.01), and regularity of patients' self monitoring of blood glucose level (P < 0.01). Among drug factors which found to affect significantly the rate of medication adherence are the number of drugs taken (P < 0.05), complexity of drug regimen (P < 0.01), and the presence of drug side effects (P < 0.01). Economical factor played an equally important role. Direct and indirect care costs in relation to patients' income were significantly affecting the rate of adherence to medication (P < 0.01). CONCLUSIONS An improvement with the adherence to oral hypoglycemic agent(s) may be achieved through continuing patient education about diabetes, improvement of patients' economical levels as well as a reduction in the cost of medication. Pharmaceutical companies have to be involved and pharmacists have to be payed for helping chronically ill patients to take their medicines correctly for improving clinical outcomes.

Abstract
BACKGROUND Diabetic patients' experience and knowledge about their medication play an important role in determining the success of long-term adherence in their disease management. OBJECTIVE This study aimed to explore diabetic patients' experience and knowledge about diabetes and its medication and to understand the factors contributing to medication adherence in Malaysian population. METHODS A qualitative research approach was adopted to gain a better understanding of the current perceptions and knowledge held by diabetic patients. Twelve patients were interviewed using a semi-structured interview guide. Saturation point of the interview was reached after the 10th interview, and no more new themes emerged from the subsequent 2 interviews. All interviews were transcribed verbatim and analyzed by means of a standard content analysis framework. RESULTS A total of 4 themes were identified from the interview analysis: knowledge about diabetes and its medication, experiences of adverse effects of medication, issues related to adherence, and the impact of medical and family relationships on well-being. Most of the patients were aware of the disease known as diabetes but unaware which type of diabetes they were suffering from. None of the participants knew the adverse effects of their medication, and most of them considered it to be safe. Financial barriers, forgetfulness, self-medication, and quality of relationships with doctor and family members seem to be the factors that challenge adherence in our sample of diabetic patients. CONCLUSION This study identified a number of key themes that might be useful in enhancing the awareness of experiences, knowledge, adherence, and attitudes of Malaysian patients with diabetes. More efforts should be taken to estimate how diabetic patients take their medication, and a well-planned educational program is also required to educate and encourage patients to practice a healthy lifestyle.

Abstract
Background The effectiveness of malaria chemoprophylaxis is limited by the lack of compliance whose determinants are not well known. Methods The compliance with malaria chemoprophylaxis has been estimated and analysed by validated questionnaires administered before and after the short-term missions (about four months) in five tropical African countries of 2,093 French soldiers from 19 military companies involved in a prospective cohort study. "Correct compliance" was defined as "no missed doses" of daily drug intake during the entire mission and was analysed using multiple mixed-effect logistic regression model. Results The averaged prevalence rate of correct compliance was 46.2%, ranging from 9.6%to 76.6% according to the companies. Incorrect compliance was significantly associated with eveningness (p = 0.028), a medical history of clinical malaria (p < 0.001) and a perceived mosquito attractiveness inferior or superior to the others (p < 0.007). Correct compliance was significantly associated with the systematic use of protective measures against mosquito bites (p < 0.001), the type of military operations (combat vs. training activities, p < 0.001) and other individual factors (p < 0.05). Conclusions The identification of circumstances and profiles of persons at higher risk of lack of compliance would pave the way to specifically targeted strategies aimed to improve compliance with malaria chemoprophylaxis and, therefore, its effectiveness.

Abstract
BACKGROUND Despite the worldwide increasing burden of diabetes, there has been no corresponding scale-up of treatment in developing countries and limited evidence of program effectiveness. In 2002, in collaboration with the Ministry of Health of Cambodia, Médecins Sans Frontières initiated an outpatient program of subsidized diabetic care in two hospital-based chronic disease clinics in rural settings. We aimed to describe the outcomes of newly and previously diagnosed diabetic patients enrolled from 2002 to 2008. METHODS We calculated the mean and proportion of patients who met the recommended treatment targets, and the drop from baseline values for random blood glucose (RBG), hemoglobin A1c (HbA1c), blood pressure (BP), and body mass index (BMI) at regular intervals. Analysis was restricted to patients not lost to follow-up. We used the t test to compare baseline and subsequent paired values. RESULTS Of 4404 patients enrolled, 2,872 (65%) were still in care at the time of the study, 24 (0.5%) had died, and 1,508 (34%) were lost to follow-up. Median age was 53 years, 2,905 (66%) were female and 4,350 (99%) had type 2 diabetes. Median (interquartile range (IQR)) follow-up was 20 months (5 to 39.5 months). A total of 24% (51/210) of patients had a HbA1c concentration of <7% and 35% (709/1,995) had a RBG <145 mg/dl within 1 year. There was a significant drop of 109 mg/dl (95% confidence interval (CI) 103.1 to 114.3) in mean RBG (P < 0.001) and a drop of 2.7% (95% CI 2.3 to 3.0) in mean HbA1c (P < 0.001) between baseline and month 6. In all, 45% (327/723) and 62% (373/605) of patients with systolic or diastolic hypertension at baseline, respectively, reached = 130/80 mm Hg within 1 year. There was a drop of 13.5 mm Hg (95% CI 12.1 to 14.9) in mean systolic blood pressure (SBP) (P < 0.001), and a drop of 11.7 mm Hg (95% CI 10.8 to 12.6) in mean diastolic blood pressure (DBP) (P < 0.001) between baseline and month 6. Only 22% (90/401) patients with obesity at baseline lowered their BMI <27.5 kg/m2 after 1 year. Factors associated with loss to follow-up were male sex, age >60 years, living outside the province, normal BMI on admission, high RBG on last visit, and coming late for the last consultation. CONCLUSION Significant and clinically important improvements in glycemia and BP were observed, but a relatively low proportion of diabetic patients reached treatment targets. These results and the high loss to follow-up rate highlight the challenges of delivering diabetic care in rural, resource-limited settings.
