International Journal of Environmental Health Research. 00:1–18., Number 00: Taylor & Francis AbstractWebsite

Poorly maintained living conditions and infrastructure are the banes of Nigerian prisons. The study investigated its environmental conditions and the prevalent diseases among inmates. The descriptive, cross-sectional study enrolled 420-inmates through a multistage sampling technique. Pre-tested instruments were administered and results presented with descriptive and logistic regression to identify predictors of toilet-cleaning and handwashing practices at P∝0.05. The mean(±SD) age and modal inmates/cell were 30±7.2 years and 36. Most inmates were males (97%), await-trial (79%) and lives in overcrowded cells (58%). Sixty-nine percent of free-cells has pour-flush toilets and 36% waits for 2–5 minutes before accessing toilets. Fifty-three percent of inmates clean latrines with water and soap, 71% burn solid waste while handwashing period-prevalence was 36%. Religion, toilet-cleaning, and education were predictors of handwashing while types of toilets and access predict toilet-cleaning behaviour. Malaria (81.1%) and scabies (7.3%) were endemic. The prison rehabilitation shall satisfy basic life needs and promote prisoners' health.

Abstract

The aim of the study was to assess if there were significant differences in the adoption of COVID-19 risk preventive behaviors and experience of food insecurity by people living with and without HIV in Nigeria. This was a cross-sectional study that recruited a convenience sample of 4471 (20.5% HIV positive) adults in Nigeria. Binary logistic regression analysis was conducted to test the associations between the explanatory variable (HIV positive and non-positive status) and the outcome variables-COVID-19 related behavior changes (physical distancing, isolation/quarantine, working remotely) and food insecurity (hungry but did not eat, cut the size of meals/skip meals) controlling for age, sex at birth, COVID-19 status, and medical status of respondents. Significantly fewer people living with HIV (PLWH) reported a positive COVID-19 test result; and had lower odds of practicing COVID-19 risk preventive behaviors. In comparison with those living without HIV, PLWH had higher odds of cutting meal sizes as a food security measure (AOR: 3.18; 95% CI 2.60-3.88) and lower odds of being hungry and not eating (AOR: 0.24; 95% CI 0.20-0.30). In conclusion, associations between HIV status, COVID-19 preventive behaviors and food security are highly complex and warrant further in-depth to unravel the incongruities identified.

Abstract

An online survey was conducted to identify factors associated with financial insecurity, food insecurity and poor quality of daily lives of adults in Nigeria during the first wave of the COVID-19 pandemic. The associations between the outcome (experience of financial loss, changes in food intake and impact of the pandemic on daily lives) and the explanatory (age, sex, education level, anxiety, depression, HIV status) variables were determined using logistic regression analysis. Of the 4439 respondents, 2487 (56.0%) were financially insecure, 907 (20.4%) decreased food intake and 4029 (90.8%) had their daily life negatively impacted. Males (AOR:0.84), people who felt depressed (AOR:0.62) and people living with HIV -PLHIV- (AOR:0.70) had significantly lower odds of financial insecurity. Older respondents (AOR:1.01) had significantly higher odds of financial insecurity. Those depressed (AOR:0.62) and PLHIV (AOR:0.55) had significantly lower odds of reporting decreased food intake. Respondents who felt anxious (AOR:0.07), depressed (AOR: 0.48) and who were PLHIV (AOR:0.68) had significantly lower odds of reporting a negative impact of the pandemic on their daily lives. We concluded the study findings may reflect a complex relationship between financial insecurity, food insecurity, poor quality of life, mental health, and socioeconomic status of adults living in Nigeria during the COVID-19 pandemic.

Objective: Bullying behaviour is pervasive, cuts across age group, transcends geographical location and its impacts include but not limited to physical or academic snags. The objective of the study is to determine bullying roles and their association with emotional or behavioural problems among adolescents in Ilesa, Nigeria. Methods: A cross-sectional study was performed on 432 senior secondary school students (12-18 years old) in Ilesa (Nigeria). Peer Relationship Questionnaire was used to determine bullying roles and the Strength and Difficulty Questionnaire to measure behavioural problems. Results: Prevalence of bullying behaviour is high. The bully-victims had the highest means score on all subscales except pro-social. Similarly, the bully-victims was significantly associated with all subscales of the SDQ except the pro-social problems at (P< .001), (P=.024), (P= .004), (P= .004), and (P< .001) for conduct, emotional problem, hyperactivity problem, peer relationship problem and the total difficulty score respectively. Conclusion: This shows that participating in bullying behaviour irrespective of the role played increases the likelihood of psychological consequences, especially the bully-victim. There is a need to establish anti-bullying programs in schools to curb this menace and its mental health consequence.

Jimoh, M, Okunlola G, Wahab A, Oseni OM, Rufai A.  2021.  Proximate and mineral analysis and antinutrient and antimicrobial properties of Talinum triangulare (Talinaceae) and Celosia argentea (Amaranthaceae), 2021/01/22. 26:449-455. Abstract

Talinum triangulare and Celosia argentea are two common underutilized leafy vegetables in Nigeria. This work was carried out to determine the mineral, proximate, and antinutritional contents of the plants, which were estimated by standard methods. Antibacterial activity of the leaf aqueous and ethanolic extracts was also evaluated against some bacteria. Results obtained from the study have shown that the two plants had constituents that show them as a good source of nutritional and medicinal benefits.

Journal of the Neurological Sciences. 428 Abstract

Background The burden of stroke in Africa is high. Understanding how age associates with major modifiable stroke risk factors could inform tailored demographic stroke prevention strategies. Purpose To quantify the magnitude and direction of the effect sizes of key modifiable stroke risk factors according to three age groups: <50 years (young), 50–65 years (middle age) and > 65 years (elderly) in West Africa. Methods This was a case-control study involving 15 sites in Ghana and Nigeria. Cases included adults aged ≥18 years with CT/MRI scan-typed stroke. Controls were age-and gender-matched stroke-free adults. Detailed evaluations for vascular, lifestyle and psychosocial factors were performed. We estimated adjusted odds ratios (aOR) using conditional logistic regression and population attributable risk (PAR) with 95% Confidence Interval of vascular risk factors by age groups. Results Among 3553 stroke cases, 813 (22.9%) were young, 1441 (40.6%) were middle-aged and 1299 (36.6%) were elderly. Among the 5 co-shared risk factors, dyslipidemia with PAR and aOR (95%CI) of 62.20% (52.82–71.58) and 4.13 (2.64–6.46) was highest among the young age group; hypertension with PAR of 94.31% (91.82–96.80) and aOR of 28.93 (15.10–55.44) was highest among the middle-age group. Diabetes with PAR of 32.29%(27.52–37.05) and aOR of 3.49 (2.56–4.75); meat consumption with PAR of 42.34%(32.33–52.35) and aOR of 2.40 (1.76, 3.26); and non-consumption of green vegetables, PAR of 16.81%(12.02–21.60) and aOR of 2.23 (1.60–3.12) were highest among the elderly age group. However confidence intervals of risk estimates overlapped across age groups. Additionally, among the young age group cigarette smoking, psychosocial stress and cardiac disease were independently associated with stroke. Furthermore, education, stress, physical inactivity and salt intake were associated with stroke in the middle-age group while cardiac disease was associated with stroke in the elderly age group. Conclusion There is a differential influence of age on the associations of major risk factors with stroke in this West African cohort. Targeting modifiable factors predominant within an age group may be more effective as a stroke prevention strategy.

Journal of Stroke and Cerebrovascular Diseases. 30(10) Abstract

Background: Stroke risk can be quantified using risk factors whose effect sizes vary by geography and race. No stroke risk assessment tool exists to estimate aggregate stroke risk for indigenous African. Objectives: To develop Afrocentric risk-scoring models for stroke occurrence. Materials and Methods: We evaluated 3533 radiologically confirmed West African stroke cases paired 1:1 with age-, and sex-matched stroke-free controls in the SIREN study. The 7,066 subjects were randomly split into a training and testing set at the ratio of 85:15. Conditional logistic regression models were constructed by including 17 putative factors linked to stroke occurrence using the training set. Significant risk factors were assigned constant and standardized statistical weights based on regression coefficients (β) to develop an additive risk scoring system on a scale of 0–100%. Using the testing set, Receiver Operating Characteristics (ROC) curves were constructed to obtain a total score to serve as cut-off to discriminate between cases and controls. We calculated sensitivity, specificity, positive predictive value (PPV) and negative predictive value (NPV) at this cut-off. Results: For stroke occurrence, we identified 15 traditional vascular factors. Cohen's kappa for validity was maximal at a total risk score of 56% using both statistical weighting approaches to risk quantification and in both datasets. The risk score had a predictive accuracy of 76% (95%CI: 74–79%), sensitivity of 80.3%, specificity of 63.0%, PPV of 68.5% and NPV of 76.2% in the test dataset. For ischemic strokes, 12 risk factors had predictive accuracy of 78% (95%CI: 74–81%). For hemorrhagic strokes, 7 factors had a predictive accuracy of 79% (95%CI: 73–84%). Conclusions: The SIREN models quantify aggregate stroke risk in indigenous West Africans with good accuracy. Prospective studies are needed to validate this instrument for stroke prevention.
