Evaluation of the physicochemical properties and bacterial loads of selected rivers in Ondo State, Nigeria.

Background and Objectives: Water is crucial to human existence but may be contaminated with microorganisms, thus making it unfit for consumption. This study aimed to evaluate the physicochemical properties and bacterial loads of selected river waters in Ondo State, Nigeria. Materials and Methods: Ten major rivers were sampled between April and August, 2021. The pH, temperature, total alkalinity, colour, turbidity, electrical conductivity, dissolved oxygen, ammonium, aluminium, organic matters, nitrate levels including the microbial loads were determined according to standard procedures. Confirmation of identified isolates was achieved by API 20E and API 20NE. Results: The turbidity, colour, conductivity, ammonium, and aluminium ranged from 4.3 to 15.2 NTU, 4 to 20 NTU, 123.5 to 580.2 mgL-1, 0 to 3.5 mgL-1, and 0.05 to 1.7, respectively. Most physicochemical parameters showed no significant differences from the WHO permissible limits for drinking water (p > 0.05). The total viable bacterial count in the rivers ranged from 1.5 × 105 to 6.3 × 105 CFUmL-1, while the total coliform count ranged from 1.3 × 103 to 4.8 × 103 CFUmL-1. The predominant bacteria were Escherichia coli and Pseudomonas aeruginosa. Conclusion: This study revealed that the physiochemical properties of the waters were majorly within the WHO permissible standards but with significantly higher bacterial loads.

A nutrition education programme improves quality of life but not anthropometric status of adults living with HIV in Abeokuta, Nigeria.

OBJECTIVE: The focus of interventions for adults living with HIV (ALH) in Nigeria has been mostly on prevention and provision of antiretroviral therapy (ART) with little consideration to nutrition-related matters. Therefore, the present study aimed to improve the quality of life (QoL) and anthropometric status of ALH in Abeokuta, Nigeria. DESIGN: A quasi-experimental design where 200 conveniently selected participants were stratified by gender and duration on ART. The intervention group (n 100) received the nutrition education programme (NEP) for 12 weeks. The control group received a brochure on nutrition guidelines for ALH. Socio-biographical information, QoL and anthropometric status were assessed using previously validated questionnaires and standard techniques at baseline, week 12 and week 24. Generalised least squares (GLS) regression analysis was used for group comparisons. Anthropometric status was summarised by gender. SETTING: Two tertiary hospitals in Abeokuta, Nigeria. PARTICIPANTS: ALH. RESULTS: The NEP led to significant improvement in the physical functioning (week 12 and 24: P < 0·01), role limitation due to physical health (week 12: P = 0·01; week 24: P = 0·002) and pain (week 12: P = 0·01) constructs of the QoL of the intervention group compared with the control group. There was no significant difference (P = 0·07) between the mean weights of the two groups at baseline. CONCLUSIONS: There was a significant improvement at week 12 and week 24 in the QoL of the intervention participants. The results indicated that a tailored NEP could make a positive contribution to the management of ALH.

Development, Implementation, and Process Evaluation of a Theory-Based Nutrition Education Programme for Adults Living With HIV in Abeokuta, Nigeria.

Introduction: Healthy diets play a role in the management and care for adults living with HIV/AIDS (ALH). Appropriate nutrition education (NE) is necessary to equip ALH with relevant knowledge and skills for healthy eating. A needs assessment identified the need for a nutrition education programme (NEP) as part of the nutrition service for ALH in Abeokuta, Nigeria. The aim of this study was to design a theory-based NEP and to evaluate the implementation process among ALH attending selected federal and state hospitals in Abeokuta as out-patients. Materials and Methods: An exploratory descriptive needs assessment in the qualitative and quantitative domains was conducted among a convenient sample of ALH (N = 243) at the selected hospitals. The quantitative needs assessment identified needs for improvement in the primary outcome [quality of life (QoL)] and the secondary outcomes [quality of dietary intake, nutrition knowledge, attitudes, and practice (KAP), and anthropometric status]. Participants' perceptions of the NEP were obtained using an interviewer administered questionnaire among 70 ALH who attended the implementation of the NEP and process evaluation thereof at the intervention hospital. Results: The qualitative results identified a lack of knowledge on planning varied meals with limited resources. The identified needs, existing guidelines and literature were integrated with appropriate constructs of the Social Cognitive Theory (SCT) and the Health Belief Model (HBM) into the NEP. The NE manual, participant's work book, flipcharts, and the brochure were tailored to address the identified challenges. Discussion: The process evaluation showed that the NEP was implemented as planned and that the participants' perceptions were positive. The use of the NE manual, participant's work book, flipcharts, and brochure demonstrated the practicality of incorporating behavioral theories in NE for ALH.
