A structural equation modelling approach to understanding the determinants of childhood vaccination in Nigeria, Uganda and Guinea.

Vaccines have contributed to reductions in morbidity and mortality from preventable diseases globally, but low demand for vaccination threatens to reverse these gains. Explorations of the determinants of vaccination uptake may rely on proxy variables to describe complex phenomena and construct models without reference to underlying theories of vaccine demand. This study aimed to use the results of a formative qualitative study (described elsewhere) to construct and test a model to explain the determinants of vaccination uptake. Using the results of a survey among more than 3,000 primary caregivers of young children in Nigeria, Uganda and Guinea, factor analysis produced six explanatory factors. We then estimated the effects of each of these factors on uptake of immunization using a structural equation model. The results showed that the probability that a child is fully vaccinated increases if a caregiver has support from others to vaccinate them (B = 0.33, ß = 0.21, p<0.001) and if caregivers had poor experiences with the healthcare system (B = 0.09, ß = 0.09, p = 0.007). Conversely, the probability of full vaccination decreases if the caregiver's husband exerts control over her decision-making ability (B = -0.29, ß = -0.20, p<0.001), or if the caregiver perceives vaccines to be of low importance (B = -0.37, ß = -0.27, p<0.001). Belief in religious protection (B = -0.07, ß = -0.05, p = 0.118) and a belief that vaccines are harmful (B = -0.12, ß = -0.04, p = 0.320) did not have an observed effect on vaccination status. This research suggests that interventions may benefit from that including entire families and communities in their design.

Prevalence and effects of menstrual disorders on quality of life of female undergraduate students in Makerere University College of health sciences, a cross sectional survey.

BACKGROUND: Menstrual problems affect as high as 90% of adolescent females and are the main reason for gynecology visits. Dysmenorrhea was the most frequent menstrual disorder for which adolescents and their parents were referred to a physician. Many undergraduate students are adolescents who undergo several hormonal changes that affect menstrual patterns. This study aimed to determine the prevalence of menstrual disorders and to determine the effect of menstrual disorders on quality of life (QOL) of female undergraduate students at Makerere University college of health sciences. METHODS: A cross sectional study design using a self-administered questionnaire. WHO (World Health Organization) QOL-BREF (QOL-Best Available Reference document) questionnaire was used to assess QOL of participants. Collected data was double entered into EPIDATA, and transferred to STATA for analysis. Data was presented using tables, and analyzed using percentages, frequencies, medians, interquartile range, means and standard deviations, t-test and ANOVA were used to establish statistical significance. P < 0.05 was considered statistically significant. RESULTS: Of the participants, 275 were included in the data analysis. The median age of the participants was 21 years with range of 18-39 years and interquartile range of 20-24 years. All the participants had attained menarche. Of the participants, 97.8% (95%CI: 95.2-99.0) (269/275) reported some form of menstrual disorder. Premenstrual symptoms were the commonest disorder (93.8% (95%CI: 90.2-96.1), N = 258) followed by dysmenorrhea (63.6% (95% CI: 57.7-69.1), N = 175), irregular menstruation (20.7% (95%CI: 16.3-25.9), N = 57), frequent menstruation (7.3% 95% CI:4.7-11.0, N = 20) and infrequent menstruation (3.3% (95% CI:1.7-6.2), N = 9). Dysmenorrhea and premenstrual symptoms significantly reduced the QOL scores of participants. CONCLUSION: Menstrual disorders were highly prevalent with negative effects on QOL and class attendance. Efforts should be made to screen and possibly treat menstrual disorders among university students as well as to conduct further studies to elucidate more on the effects of menstrual disorders on quality of life.

Applying a social-ecological model to understand factors impacting demand for childhood vaccinations in Nigeria, Uganda, and Guinea.

Vaccines have reduced child mortality across the world, but low levels of demand for vaccination threatens to undermine progress. Existing frameworks to understand demand tend to prioritise primary caregivers' decision-making processes. We aimed to build a wider understanding of vaccine demand by applying an adapted socio-ecological model to analyse 158 interviews with primary caregivers and fathers of young children, and community influencers in Nigeria, Uganda, and Guinea. We found that several factors come together to inform a primary caregiver's demand for vaccination, including their familial and social relationships, their interactions with government and healthcare institutions, and the wider social and cultural norms in their communities. The study suggests that interventions targeted at families and communities instead of individuals could be effective. The results could be used to ensure that vaccine demand frameworks used by researchers and intervention designers are comprehensive and consider a wider range of influences on the primary caregiver.
