Correlates of intimate partner violence among adolescents in East Africa: a multi-country analysis

Introduction

intimate partner violence (IPV) is a global concern not only among adults but also adolescents. It has been reported that 35% of adolescent women have ever experienced IPV - occuring more so in non-industrialized countries. This study sought to understand the correlates associated with experiencing IPV among adolescent women between the ages 15 and 24 in five East African countries: Burundi, Kenya, Rwanda, Tanzania, and Uganda.

Methods

this was a secondary analysis of Demographic and Health Survey (DHS) data on adolescent women aged 15-24 years in five East African countries. IPV was measured as a composite variable of emotional, physical, and sexual violence. Other sociodemographic, income, maternal, sexual, knowledge, behavioral, and partner-related variables were included in the analysis.

Results

the prevalence of ever experiencing IPV was 45.1% (n=2380). A higher proportion of women who reported experiencing IPV had their first sexual encounter when they were less than 18 years of age (p<0.001). The adjusted odds ratio (aOR) of experiencing IPV increased almost two times for women who were aged 18-24 years (aOR: 1.7; CI: 1.3-2.3), almost four times (aOR 3.8; CI: 1.7-8.3) for those who had two or more children, and two-fold for women who had ever terminated a pregnancy compared to those who had not (aOR 2.2; CI: 1.0-4.9). Additionally, there was a higher odds (aOR: 1.5 (1.0-2.3)) of experiencing IPV if the respondent believed their husband/spouse´s abuse was justified.

Conclusion

raising early awareness and educating both the young males and females appropriately to mitigate contributing factors to IPV could ensure stable, healthy relationships free of domestic violence in the future.

Role of the conserved phenylalanine 181 of NADPH-cytochrome P450 oxidoreductase in FMN binding and catalytic activity

NADPH-cytochrome P450 oxidoreductase (P450 reductase, EC 1.6.2.4) is an essential component of the P450 monooxygenase complex and binds FMN, FAD, and NADPH cofactors. Residues Tyr140 and Tyr178 are known to be involved in FMN binding. A third aromatic side chain, Phe181, is also located in the proximity of the FMN ring and is highly conserved in FMN-binding proteins, suggesting an important functional role. This role has been investigated by site-directed mutagenesis. Substitution of Phe181 with leucine or glutamine decreased the cytochrome c reductase activity of the enzyme by approximately 50%. Ferricyanide reductase activity was unaffected, indicating that the FAD domain was unperturbed. The mutant FMN domains were expressed in Escherichia coli, and the redox potentials and binding energies of their complexes with FMN were determined. The affinity for FMN was decreased approximately 50-fold in the Leu181 and Gln181 mutants. Comparison of the binding energies of the wild-type and mutant enzymes in the three redox states of FMN suggests that Phe181 stabilizes the FMN-apoprotein complex. The amide 1H and 15N resonances of the Phe181Leu FMN domain were assigned; comparison of their chemical shifts with those of the wild-type domain indicated that the effect of the substitution on FMN affinity results from perturbation of two loops which form part of the FMN binding site. The results indicate that Phe181 cooperates with Tyr140 and Tyr178 to play a major role in the binding and stability of FMN.
