Review of: "Factors Associated with Contraceptive Use Among Migrant Female Head Porters in the Kumasi Metropolis"
Résumé
The title is brief explaining what to be studied, study subject, objective and study design.The manuscript describes the demographic, socio-economic and health-related predictors of Contraceptive use among female head porters in Ghana.The fourth and fifth paragraphs of the "Introduction" section well depict the justification behind this study.The abstract, introduction, method and result were presented well.However, the study used convenient sampling method and applied analytic cross sectional study.The authors mentioned "there is no adequate statistic to come up with sampling-farm that will yield to probability sampling method.At the same time, authors mentioned that female head porters (FHP=better to use abbreviations once written in full for the first time) live in clusters, for the sake of security.Using these clusters as sampling unit, it would have been better the sampling method used probability sampling method (random samples from conveniently selected clusters) for the result to be inferred to the wider study population and avail itself for better predictive analysis.This could have been done as the clusters/groups have leaders as reported on the "population" under study method.Also, there is no justification "why" and "how" the four clusters selected by the researchers, which could give us whether this could be considered representing the study population or help us understand how far this piece of work is scientific, as rigorous analytic method is used on the data collected (multivariate logistic regression analysis: I hope you mean binary logistic regression analysis as you are dealing with dichotomous outcome variable=contraceptive use ).The data has internal validity as long as it measures what it has to measure for the specific sample population studied with minimum bias incurred, but difficult to say it has external validity as the sampling method used was convenient (nonprobability) inferring to the wider study population.It is also advisable to indicate those factors that showed statistical significance, particularly while presenting on the abstract.However, factors not showing statistical significance but having clinical significance can be presented under result and discussed under discussion.Also, data collection was done using both closed and open ended questions, but no mention how the open ended questions were handled.Additionally, there is no pre-test conducted to test the tool or there is nothing that mentions whether the tool is standard validated tool that has been used elsewhere, before this study.Finally, the ethical clearance is well written, but it did not indicate the data storage and security issues, which is very critical.
