Factors affecting willingness to comply with public health measures during the pandemic among sub-Sahara Africans.

Background: The unprecedented outbreak of coronavirus disease (COVID-19) drastically spread worldwide, resulting in extraordinary measures put in place in various countries including Sub Saharan Africa (SSA) countries.

Objective: To assess the factors associated with compliance with the public health measures imposed by various SSA countries.

Method: Cross sectional study using self-administered surveys distributed on social media platforms between April 18th and May 16th, 2020, corresponding with the mandatory lockdown period in most SSA countries.

Economic, Health and Physical Impacts of COVID-19 Pandemic in Sub-Saharan African Regions: A Cross Sectional Survey.

Purpose: The key preventive measures adopted to minimise the spread of the coronavirus disease (COVID-19) had significant health, economic and physical impacts mostly in developing countries. This study evaluated the health, economic and physical impacts of COVID-19 lockdown measures among sub-Saharan African (SSA) population and associated demographic variations.

Methods: A total of 1970 respondents took part in this web-based cross-sectional survey during the mandatory lockdown period in most SSA.

Differences in Perceived Risk of Contracting SARS-CoV-2 during and after the Lockdown in Sub-Saharan African Countries.

This study investigated risk perception of contracting and dying of SARS-CoV-2 in sub-Sahara Africa during and after the lockdown periods. Two online surveys were conducted one year apart, with participants 18 years and above living in sub-Sahara Africa or the diaspora. Each survey took four weeks.

Risk perception of COVID-19 among sub-Sahara Africans: a web-based comparative survey of local and diaspora residents.

Background: Perceived risk towards the coronavirus pandemic is key to improved compliance with public health measures to reduce the infection rates. This study investigated how Sub-Saharan Africans (SSA) living in their respective countries and those in the diaspora perceive their risk of getting infected by the COVID-19 virus as well as the associated factors.

Methods: A web-based cross-sectional survey on 1969 participants aged 18 years and above (55.

Knowledge, Attitudes, and Perceptions of COVID-19 Among Healthcare and Non-Healthcare Workers in Sub-Saharan Africa: A Web-Based Survey.

Due to the current COVID-19 pandemic and associated high mortality in sub-Saharan Africa, there is panic among healthcare workers because of the higher risk of being infected. This study compared knowledge, attitudes, and perceptions of COVID-19 among healthcare workers (HCWs) and non-healthcare workers (non-HCWs) and examined common associated factors. A web-based cross-sectional study of 1,871 respondents (430 HCWs and 1,441 non-HCWs) was conducted while lockdown measures were in place in 4 regions of sub-Saharan Africa.

Misinformation About COVID-19 in Sub-Saharan Africa: Evidence from a Cross-Sectional Survey.

Misinformation about coronavirus disease 2019 (COVID-19) is a significant threat to global public health because it can inadvertently exacerbate public health challenges by promoting spread of the disease. This study used a convenience sampling technique to examine factors associated with misinformation about COVID-19 in sub-Saharan Africa using an online cross-sectional survey. A link to the online self-administered questionnaire was distributed to 1,969 participants through social media platforms and the authors' email networks.

Prevalence and Factors Associated with Mental and Emotional Health Outcomes among Africans during the COVID-19 Lockdown Period-A Web-based Cross-Sectional Study.

Mental health and emotional responses to the effects of COVID-19 lockdown in sub-Saharan Africa (SSA) are of serious public health concern and may negatively affect the mental health status of people. Hence, this study assessed the prevalence of mental health symptoms as well as emotional reactions among sub-Saharan Africans (SSAs) and associated factors among SSAs during the COVID-19 lockdown period. This was a web-based cross-sectional study on mental health and emotional features from 2005 respondents in seven SSA countries.

Comparison of measured with calculated amplitude of accommodation in Nigerian children aged six to 16 years.

Purpose: Amplitude of accommodation varies with race and ethnicity and Hofstetter's equations are commonly used in Nigeria to calculate expected amplitude of accommodation for clinical purposes. The aim of this study was to present normative values for amplitude of accommodation for Nigerian children and to compare the measured values with those calculated using Hofstetter's equations.

Methods: A total of 688 children aged six to 16 years from three selected cities in Nigeria were included in the study.

Vergence findings and horizontal vergence dysfunction among first year university students in Benin City, Nigeria.

Purpose: The study was designed to determine the prevalence of vergence dysfunctions among first year university students in Nigeria and to document the measures that define the vergence system of the visual system.

Methods: A cross-sectional study of first year students of the University of Benin, Benin City, Nigeria, who presented for the mandatory eye examination as part of their medical examinations required for clearance was conducted. A battery of tests that defines the vergence system including near and far phoria, positive and negative fusional vergence amplitudes at far and near, near point of convergence (NPC) and AC/A ratio were measured using conventional clinical protocols.

Knowledge of diabetes and its associated ocular manifestations by diabetic patients: A study at Korle-Bu Teaching Hospital, Ghana.

Background: Diabetes mellitus is a significant cause of visual impairment, hence adequate knowledge on this condition and its ocular manifestations is of immense importance to diabetic patients.

Aim: To assess the knowledge of diabetic patients on the disorder and its ocular manifestations, and their attitude towards ocular examinations.

Materials And Methods: A cross-sectional survey involving the use of a structured interview was conducted among diabetic patients attending the Diabetic Clinic of the Korle-Bu Teaching Hospital.

Investigation of amplitude of accommodation among Ghanaian school children.

Background: Deficient amplitude of accommodation is the most frequently used criteria in an optometric practice in diagnosing whether a patient has accommodative insufficiency. This deficiency is determined based on an age-related expected finding calculated using Hofstetter's equation derived from Donder's and Duane's data. The aim of the present study was to investigate the amplitude of accommodation among Ghanaian school children and to compare the findings with age-expected norms predicted by Hofstetter's equation.
