  1. Fulltext Epidemiology of latent tuberculosis infection among patients with and without diabetes mellitus
    Swarna Nantha Y, Puri A, Mohamad Ali SZ, Suppiah P, Che Ali SA, Ramasamy B, et al.
    Fam Pract, 2017 09 01;34(5):532-538.
    PMID: 28369346 DOI: 10.1093/fampra/cmx017
    Background: Individuals with type 2 diabetes mellitus (DM) are at a greater risk of tuberculosis (TB) reactivation. There is a paucity of information about the risk factors associated with latent tuberculosis infection (LTBI) in patients with diabetes.

    Objective: We conducted an observational study to compare the prevalence and risk factors associated with LTBI factors in Malaysian adults with and without DM.

    Methods: Four hundred and four patients with DM and 359 patients with non-DM at a regional primary care clinic were recruited as participants in this case-control study. The tuberculin sensitivity test (TST) was performed. The presence of LTBI was defined by a TST value of 10 mm in DM patients and 10 mm in the non-DM group. A logistic regression model was used to identify variables associated with LTBI.

    Results: There was no statistical significant difference in the prevalence rates seen between the DM and non-DM group of the study. LTBI prevalence among patients with DM was 28.5%. The proportion of patients in the non-DM group with LTBI was 29.2%. When a critical cut-off of 8 mm was used, the adjusted odds ratio of LTBI in DM patients was 1.88 (95% confidence interval: 1.22-2.82). Smoking was an independent risk factor for LTBI regardless of DM status. HbA1c levels or anthropometric measurements were not associated with LTBI in diabetic patients.

    Conclusions: There is no significant risk of contracting LTBI in DM patients using the standard 10-mm TST cut-off. Nonetheless, using lower cut-offs in a DM population appear valid. Smoking is an important predictor of LTBI.
  2. Fulltext The validation of the Malay Yale Food Addiction Scale 2.0: factor structure, item analysis and model fit

    Public Health Nutr, 2020 Feb;23(3):402-409.
    PMID: 31538554 DOI: 10.1017/S1368980019002684
    OBJECTIVE: The development of a second version of the Yale Food Addiction Scale (YFAS) coincides with the latest updates in the diagnosis of addiction as documented in the 5th edition of the Diagnostic and Statistical Manual of Mental Disorders. The objective of the present study was to translate the YFAS 2.0 into the Malay language and test its psychometric properties in a primary-care population.

    DESIGN: Patients were assessed for food addiction utilizing the Malay YFAS 2.0. The participants were also assessed for eating disorder using the validated Malay Binge Eating Scale. The psychometric properties of the YFAS 2.0 were determined by analysing factor structure, overall item statistics, internal consistency and construct validity.

    SETTING: Between 2017 and 2018, participants were chosen from a regional primary-care clinic in the district of Seremban, Malaysia.

    PARTICIPANTS: Patients (n 382) from a regional primary-care clinic.

    RESULTS: The prevalence of food addiction was 5·0%. A two-factor structure of the YFAS was confirmed as the most optimal solution for the scale via confirmatory factor analysis. In both its diagnostic and symptom count version, the YFAS 2.0 had good internal consistency (Kuder-Richardson α > 0·80 and McDonald's ω > 0·9).

    CONCLUSIONS: We validated a psychometrically sound Malay version of the YFAS 2.0 in a primary-care population. Both diagnostic and symptom count versions of the scale had robust psychometric properties. The questionnaire can be used to develop health promotion strategies to detect food addiction tendencies in a general population.
