Menstrual health and hygiene knowledge among post menarche adolescent school girls in urban and rural Tanzania.

Adolescent girls' capacity to lead healthy lives and perform well in school has been hampered by their lack of awareness about menstruation and the requirements for its hygienic management. Lack of enabling infrastructure, improper menstrual supplies, and limited socioeconomic support for good menstrual health and cleanliness are characteristics of schools in Africa South of the Sahara. We evaluated school-age girls' knowledge of menstrual hygiene and identified bottlenecks that could affect policy and programming for menstrual health and hygiene. A school-based cross-sectional study involved 8,012 adolescent school girls in the age group of 11-18 years (mean age = 14.9 years). The study evaluated students' knowledge of menstrual health and hygiene (MHH) from the viewpoints of schools and communities using a combination of qualitative and quantitative approaches. Data was collected using self-administered surveys, focus group discussions, in-depth interviews, and site observations. Girls' older age (AOR = 1.62, P 0.001), having a female guardian (AOR = 1.39: P = 001), and having a parent in a formal job (AOR = 1.03: P 0.023) were positively associated with Menstrual health and Hygiene Knowledge. MHH knowledge levels varied significantly between girls attending government (53.3) and non-government schools (50.5%, P = 0.0001), although they were comparable for girls attending rural and urban schools. Only 21% of the study's schools had at least one instructor who had received training in MHH instruction for students. We have established that the majority of adolescent girls in schools have inadequate knowledge on menstrual health and hygiene, and that school teachers lack the skills to prepare and support young adolescents as they transition into puberty. Concerted actions aimed at building supportive policy are paramount, for school-aged teenagers to learn about and reap the long-term advantages of good menstrual health practices.

Susceptibility Status of Bedbugs (Hemiptera: Cimicidae) Against Pyrethroid and Organophosphate Insecticides in Dar es Salaam, Tanzania.

Cimex hemipterus resistance to residual insecticides is a growing public health concern worldwide. Herein, we report the susceptibility status of C. hemipterus against pyrethroid (permethrin) and organophosphate (dichlorvos) insecticides in Dar es Salaam. The knockdown efficacy of dichlorvos (99%) was greater than that of permethrin (43%), and mortality at the end of 24 h was also greater for dichlorvos than for permethrin. Mortality in recommended concentration of permethrin was lower than manufacturer's expectations. In contrast, similar concentrations in dichlorvos resulted into mortality of 100% at the end of 24 h. LC50 and LC95 values for permethrin were 3.36 (2.356-4.364) and 2,887.39 (2,886.37-2,888.39), respectively, whereas those of dichlorvos were 7.91 (3.85-11.97) and 44.39 (40.33-48.45). Dar es Salaam city has high coverage and usage of long-lasting insecticidal nets (LLINs) for prevent malaria. The resistance in bedbugs to permethrin may be related to the widespread use of the insecticide in LLINs. We recommend of the change from pyrethroids dichlorvos for the control of bedbugs.
