Question: Question: Are anticytomegalovirus antibody titres associated with caregiving burden in younger caregivers?
Answer: These data suggest that in the absence of immunosenescence, the chronic stress of caregiving is not sufficient to compromise the immune response to persistent CMV infection. However, an indirect mechanism to poorer health in caregivers might be via adoption of disadvantageous health behaviours in response to stress. Statement of contribution What is already known on this subject? Older caregivers of spouses with dementia show a poorer immune response against latent viruses when compared to age- and sex-matched controls. Younger parental caregivers of children with developmental disabilities show a poorer antibody response to vaccination. What does this study add? The study showed no association between caregiving stress and CMV antibody titre in young caregivers. There were higher CMV antibody titres in the caregivers who engage in unhealthy behaviours.

Answer: no


Question: Question: Do urban settings ensure access to services : findings from the immunisation programme in Kampala Uganda?
Answer: Complex health system barriers to childhood immunisation still exist in this urban setting; emphasizing that even in urban areas with great physical access, there are hard to reach people. As the rate of urbanization increases especially in sub-Saharan Africa, governments should strengthen health systems to cater for increasing urban populations.

Answer: no


Question: Question: Do infant and young child feeding practices differ by ethnicity of Vietnamese mothers?

Complementary feeding practices were less optimal among ethnic minorities compared to Kinh, which suggests need for broad intervention including improved food availability, accessibility, and security.

Answer:
yes
