Human caliciviruses detected in HIV-seropositive children in Kenya
The human caliciviruses (HuCVs) are important causes of gastroenteritis worldwide. Norovirus (NoV) and sapovirus (SaV) have been detected in HIV-seropositive children but the genetic diversity of HuCVs circulating in these individuals is largely unknown. In this study the prevalence and genotype diversity of HuCVs circulating in Kenyan HIV-positive children, with or without diarrhea, from the year 1999 to 2000 was investigated. The overall prevalence of HuCVs was 19% with NoV predominating at 17% (18/105) and SaV present in 5.7% (6/105) of specimens. Human CVs were detected in both symptomatic (24%) and asymptomatic (16%) children. Co-infections with other enteric viruses were detected in 21.6% of children with diarrhea but only in 4.4% of children without diarrhea. Remarkable genetic diversity was observed with 12 genotypes (7 NoV, 5 SaV) being identified in 20 HuCV-infected children. NoV genogroup II (GII) strains predominated with GII.2 and GII.4 each representing 27% of the NoV-positive strains. The GII.4 strain was most closely related to the nonepidemic GII.4 Kaiso 2003 variant. Other NoV genotypes detected were GI.3, GII.6, GII.12, GII.14, and GII.17. Five different SaV genotypes (GI.2, GI.6, GII.1, GII.2, and GII.4) were characterized from six specimens. Diarrheal symptoms were not associated with any specific HuCV genotype. Overall the HuCV genotype distribution detected in this study reflects those in other studies worldwide. The strains detected are closely related to genotypes that have circulated on several continents since the year 2000.Poliomyelitis Research Foundation (PRF)of SA for research funding (Grant number 09/33).

Sociocultural factors influencing breastfeeding practices in two slums in Nairobi, Kenya
Background: Despite numerous interventions promoting optimal breastfeeding practices in Kenya, pockets of suboptimal breastfeeding practices are documented in Kenya’s urban slums. This paper describes cultural and social beliefs and practices that influence breastfeeding in two urban slums in Nairobi, Kenya.
Methods: Qualitative data were collected in Korogocho and Viwandani slums through 10 focus group discussions and 19 in-depth interviews with pregnant, breastfeeding women and community health volunteers and 11
key-informant interviews with community leaders. Interviews were audiotaped, transcribed verbatim, coded in NVIVO and analyzed thematically.
Results: Social and cultural beliefs and practices that result to suboptimal breastfeeding practices were highlighted
including; considering colostrum as ‘dirty’ or ‘curdled milk’, a curse ‘bad omen’ associated with breastfeeding while
engaging in extra marital affairs, a fear of the ‘evil eye’ (malevolent glare which is believed to be a curse associated with witchcraft) when breastfeeding in public and breastfeeding being associated with sagging breasts. Positive social and cultural beliefs were also identified including the association of breast milk with intellectual development and good child health. The beliefs and practices were learnt mainly from spouses, close relatives and peers.
Conclusion: Interventions promoting behavior change with regards to breastfeeding should focus on dispelling the beliefs and practices that result to suboptimal breastfeeding practices and to build on the positive ones, while involving spouses and other family members as they are important sources of information on breastfeeding
Factors affecting actualization of the WHO breastfeeding recommendations in urban poor settings in Kenya
Poor breastfeeding practices are widely documented in Kenya, where only a third of children are exclusively
breastfed for 6 months and only 2% in urban poor settings.This study aimed to better understand the factors that
contribute to poor breastfeeding practices in two urban slums in Nairobi, Kenya. In-depth interviews (IDIs),
focus group discussions (FGDs) and key informant interviews (KIIs) were conducted with women of childbear-
ing age, community health workers, village elders and community leaders and other knowledgeable people in the
community. A total of 19 IDIs, 10 FGDs and 11 KIIs were conducted, and were recorded and transcribed
verbatim. Data were coded in NVIVO and analysed thematically. We found that there was general awareness
regarding optimal breastfeeding practices, but the knowledge was not translated into practice, leading to
suboptimal breastfeeding practices. A number of social and structural barriers to optimal breastfeeding were
identified: (1) poverty, livelihood and living arrangements; (2) early and single motherhood; (3) poor social and
professional support; (4) poor knowledge, myths and misconceptions; (5) HIV; and (6) unintended pregnancies.
The most salient of the factors emerged as livelihoods, whereby women have to resume work shortly after
delivery and work for long hours, leaving them unable to breastfeed optimally. Women in urban poor settings
face an extremely complex situation with regard to breastfeeding due to multiple challenges and risk behaviours
often dictated to them by their circumstances. Macro-level policies and interventions that consider the ecological
setting are needed
Effectiveness of home-based nutritional counselling and support on exclusive breastfeeding in urban poor settings in Nairobi: a cluster randomized controlled trial
Background: Exclusive breastfeeding (EBF) improves infant health and survival. We tested the effectiveness of a homebased
intervention using Community Health Workers (CHWs) on EBF for six months in urban poor settings in Kenya.
Methods: We conducted a cluster-randomized controlled trial in Korogocho and Viwandani slums in Nairobi.
We recruited pregnant women and followed them until the infant’s first birthday. Fourteen community clusters
were randomized to intervention or control arm. The intervention arm received home-based nutritional
counselling during scheduled visits by CHWs trained to provide specific maternal infant and young child
nutrition (MIYCN) messages and standard care. The control arm was visited by CHWs who were not trained in
MIYCN and they provided standard care (which included aspects of ante-natal and post-natal care, family
planning, water, sanitation and hygiene, delivery with skilled attendance, immunization and community
nutrition). CHWs in both groups distributed similar information materials on MIYCN. Differences in EBF by
intervention status were tested using chi square and logistic regression, employing intention-to-treat analysis.
Results: A total of 1110 mother-child pairs were involved, about half in each arm. At baseline, demographic
and socioeconomic factors were similar between the two arms. The rates of EBF for 6 months increased from
2% pre-intervention to 55.2% (95% CI 50.4–59.9) in the intervention group and 54.6% (95% CI 50.0–59.1) in the
control group. The adjusted odds of EBF (after adjusting for baseline characteristics) were slightly higher in the
intervention arm compared to the control arm but not significantly different: for 0–2 months (OR 1.27, 95% CI
0.55 to 2.96; p = 0.550); 0–4 months (OR 1.15; 95% CI 0.54 to 2.42; p = 0.696), and 0–6 months (OR 1.11, 95% CI
0.61 to 2.02; p = 0.718).
Conclusions: EBF for six months significantly increased in both arms indicating potential effectiveness of using
CHWs to provide home-based counselling to mothers. The lack of any difference in EBF rates in the two groups
suggests potential contamination of the control arm by information reserved for the intervention arm.
Nevertheless, this study indicates a great potential for use of CHWs when they are incentivized and monitored
as an effective model of promotion of EBF, particularly in urban poor settings. Given the equivalence of the
results in both arms, the study suggests that the basic nutritional training given to CHWs in the basic primary
health care training, and/or provision of information materials may be adequate in improving EBF rates in
communities. However, further investigations on this may be needed. One contribution of these findings to
implementation science is the difficulty in finding an appropriate counterfactual for community-based
educational interventions.

Effectiveness of personalised, home-based nutritional counselling on infant feeding practices, morbidity and nutritional outcomes among infants in Nairobi slums: study protocol for a cluster randomised controlled trial
BackgroundNutrition in the first 1,000 days of life (during pregnancy and the first two years) is critical for child growth and survival. Poor maternal, infant and young child nutrition (MIYCN) practices are widely documented in Kenya, with potential detrimental effects on child growth and survival. This is particularly a problem in slums, where most urban residents live. For example, exclusive breastfeeding for the first six months is only about two per cent. Innovative strategies to reach slum residents are therefore needed. Strategies like the Baby Friendly Hospital Initiative have proven effective in some settings but their effectiveness in resource-limited settings, including slums where many women do not deliver in hospital, is questionable. We propose to test the effectiveness of a home-based intervention on infant feeding practices, nutrition and health outcomes of infants born in two slums in Nairobi, Kenya. Methods/DesignThe study, employing a cluster-randomised study design, will be conducted in two slums in Nairobi: Korogocho and Viwandani where 14 community units (defined by the Government’s health care system) will form the unit of randomization. A total of 780 pregnant women and their respective child will be recruited into the study. The mother-child pair will be followed up until the child is one year old. Recruitment will last approximately one year and three months from September 2012 to December 2013. The mothers will receive regular, personalised, home-based counselling by trained Community Health Workers on MIYCN. Regular assessment of knowledge, attitudes and practices on MIYCN will be done, coupled with assessments of nutritional status of the mother-child pairs and diarrhea morbidity for the children. Statistical methods will include analysis of covariance and multinomial logistic regression. Additionally, cost-effectiveness analysis will be done.The study is funded by the Wellcome Trust and will run from March 2012 to February 2015. DiscussionInterventions aimed at promoting optimal breastfeeding and complementary feeding practices are considered to have high impact and could prevent a fifth of the under-five deaths in countries with high mortality rates. This study will inform policy and practice in Kenya and similar settings regarding delivery mechanisms for such high-impact interventions, particularly among urban poor populations <br/
