Introduction: Diabetes Healthcare Providers (DHPs) are notable advocates of increased Physical Activity (PA) as a veritable means of preventing type 2 diabetes mellitus and related noncommunicable diseases. However, the extent to which the DHPs themselves comply with this important lifestyle habit is not known. Aim: To evaluate PA and sedentary living among DHPs in Nigeria and identify some determinants of PA in this population. Materials and Methods: In this cross-sectional study, PA was assessed using the short form of the International Physical Activity Questionnaire (IPAQ-SF). Besides socio-demographic and anthropometric indices, participants were asked about frequency and duration of engagements in vigorous PA, moderate PA, walking and average sitting time, in the past 7 days. Data were analysed using Chi-square, t-test, Spearman’s test of correlation and logistic regression statistics on SPSS version 23. Results: One hundred and eight subjects (63% males), with a mean age of 42.1±7.7 years, participated in the study. Although 86% of the participants were adjudged physically active, the intensity of PA was low in 52.8% and 74.1% did not meet the World Health Organisation recommended target for adequate PA. A significant negative correlation was observed between intensity of PA and Body Mass Index (BMI) while sitting time positively correlated with BMI. BMI ≥25 kg/m2 and higher professional cadre were significant independent predictors of low PA. Conclusion: Nearly three-quarter of DHPs in Nigeria do not engage in sufficient PA. This observation calls to question their ascribed status as role models of healthy lifestyles and may portend increased health risks among this important group of healthcare workforce. There is a significant inverse relationship between PA and BMI as well as professional cadre.

Objective:Quality of life and its correlates were studied in two groups of family caregivers of patients with major mental disorders-Schizophrenia (SZ) and Bipolar Affective Disorder (BPAD).
Method:
Family caregivers of SZ and BPAD patients were consecutively recruited to the study (n=100 for each group). Caregivers were screened for quality of life (QOL) measures, caregiver burden, symptoms of anxiety and depression, using the World Health Organization Quality of Life Scale (WHOQOL-BREF), the Pai and Kapur Family Burden Interview Schedule (FBIS) and the Hospital Anxiety and Depression Inventory (HADS) respectively.
Results:
When compared to the caregivers of the BPAD patients, the caregivers of the SZ patients had lower QOL scores in two out of the 4 WHOQOL-BREF domains (physical and psychological domains) (p=0.001), and higher overall total caregiver burden (p=0.001). On the other hand, caregivers of the BPAD patients had higher levels of depressive symptoms (p=0.001). Increased depressive symptoms were associated with lower QOL for both groups, comprising all WHOQOLBREF domains for BPAD and 3 domains for SZ caregivers. Higher caregiver burden was associated with lower QOL for both groups.
Conclusion:
There is a need for intervention and caregiver support for the relatives of patients with bipolar disorder and schizophrenia.

Many diseases including HIV/AIDS can be transmitted in the dental setting when effective infection control procedures are ignored. The aim of this study, therefore, was to evaluate the infection control knowledge and practices of Nigerian dentists in the era of HIV/AIDS.Information on knowledge of transmission of HIV, occupational vulnerability, infection control practices, and opinion on adequacy of infection control facilities were gathered from dentists through a self-administered questionnaire. Knowledge was assessed on a total score of 20 questions.
Only 3.6% of the dentists had poor knowledge. Younger males and dentists working in teaching hospitals had significantly better knowledge than their counterparts. While 40.8% believed HIV could be transmitted through saliva, only 43.2% knew it could be transmitted through the conjunctiva. Most (93.2%) wore gloves routinely and the most common barrier to glove use was non-availability. Most (79.2%) used autoclaves for sterilization; however, chemical disinfectants and boiling were also used. The majority (72.4%) believed the facilities for infection control in their centres were inadequate. Close to half of the respondents (47.6%; n = 118) rated the occupational risk of becoming infected with HIV as high.
The results of this study have shown that while the level of knowledge of the dentists was generally acceptable, there were still some misconceptions on the transmission and occupational vulnerability of HIV. It also indicates only partial compliance with recommended infection control procedures among Nigerian dentists as a result of inadequate supplies.
