Determinants of COVID-19 vaccine behaviour intentions among the youth in Kenya: a cross-sectional study.

INTRODUCTION: COVID-19 has become a public health concern globally with increased numbers of cases of the disease and deaths reported daily. The key strategy for the prevention of COVID-19 disease is to enhance mass COVID-19 vaccination. However, mass vaccination faces challenges of hesitation to acceptance of the vaccine in the community. The youth may not be among the vulnerable population to severe COVID-19 disease but are highly susceptible to contracting the virus and spreading it. The aim of the study was to assess COVID-19 vaccine youth behavior intentions and their determinants in Kenya. METHODS: The study used a mixed method design, employing a cross-sectional survey and focused group discussions across 47 counties in Urban, Peri-Urban and Rural settings of Kenya. The interviewees were youths aged 18-35, registered in online platforms/peer groups that included Shujaaz, Brck Moja, Aiffluence, Y Act and Heroes for Change. Quantitative data was collected using Google forms. A total of 665 interviews were conducted. Quantitative data was analysed using STATA version 16. In this paper we report quantitative study findings. RESULTS: The findings of the study indicated that only 42% of the youth were ready to be vaccinated, with 52% adopting a wait and see approach to what happens to those who had received the vaccine and 6% totally unwilling to be vaccinated. The determinants of these behavior intentions included: the perceived adverse effects of the vaccine on health, inadequate information about the COVID-19 vaccine, conflicting information about COVID-19 vaccine from the social media, religious implications of the vaccine, impact of education level on understanding of the vaccine, perceived risk of contracting the COVID-19 disease, efficacy of the COVID-19 vaccine, COVID-19 affecting women than men and trust in the ministry of health to lead COVID-19 interventions. Significantly it was found that hesitancy is higher among females, protestants and those with post-secondary education. Lack of information and concerns around vaccine safety and effectiveness were main cause of COVID-19 vaccine hesitancy. Social media was the major source of information contributing to hesitancy. Other contributors to hesitancy included low trust in the MoH and belief that mass vaccination is not helpful. CONCLUSION: Vaccine hesitancy remains high among the youth but the causes of it are modifiable and health systems need to have evidence based engagements with the youth to reduce vaccine hesitancy.

How to set up government-led national hygiene communication campaigns to combat COVID-19: a strategic blueprint.

While large-scale changes in population behaviour are required to reduce the transmission of the severe acute respiratory syndrome coronavirus 2 virus, the emergency context is not conducive to the sort of careful communications planning that would normally be required to meet such a task. Rapid strategic communications planning in a pandemic by governments is, however, possible and necessary. Steps include setting up a dedicated communications task force, mobilising partners and resources, developing a creative brief and theory of change and overseeing the creation, testing, roll out and revision of content. In this short guide, we argue that a minimum of strategic planning can be undertaken rapidly, and that good use can be made of simple principles of behaviour change, even during pandemics. Our aim here is to provide a blueprint that governments and their partners, especially in low-income settings, can follow to design, coordinate and resource national communications efforts to combat the COVID-19 pandemic immediately and for the longer term.

Impact of a teacher-led school handwashing program on children's handwashing with soap at school and home in Bihar, India.

Handwashing with soap is an important preventive health behavior, and yet promoting this behavior has proven challenging. We report the results of a program that trained teachers to deliver a handwashing with soap behavior change program to children in primary schools in Bihar, India. Ten intervention schools selected along with ten nearby control schools, and intervention schools received the "School of Five" program promoting handwashing with soap using interactive stories, games, and songs, behavioral diaries to encourage habit formation, and public commitment. Households with children aged 8-13 attending the nearby school were enrolled in the study. Handwashing with soap was measured using sticker diaries before eating and after defecation 4 weeks after the intervention was completed. Children in the treatment reported 15.1% more handwashing with soap on key occasions (35.2%) than those in the control group (20.1%) (RR: 1.77, CI: (1.22, 2.58), p = .003). There was no evidence that handwashing with soap after defecation was higher in the treatment group than the control group (RR: 1.18, CI: (0.88, 1.57), p = .265), but there was strong evidence that handwashing with soap was greater in the treatment than in the control before eating (RR: 2.68, 95% CI: (1.43, 5.03), p = .002). Rates of handwashing increased both at home (RR: 1.63, CI: 1.14, 2.32), p = .007) and at school (RR: 4.76, 95% CI: (1.65, 17.9), p = .004), though the impact on handwashing with soap at key occasions in schools was much higher than at home. Promoting handwashing with soap through teachers in schools may be an effective way to achieve behavior change at scale.

Integrating Face Washing into a School-Based, Handwashing Behavior Change Program to Prevent Trachoma in Turkana, Kenya.

Trachoma is the leading infectious cause of blindness, and facial cleanliness is associated with reduced odds of trachomatous inflammation and Chlamydia trachomatis infection, but there is little evidence of how to drive this behavior change at scale. We report the results of a program integrating face washing into a school-based handwashing promotion program in Turkana County, Kenya. Children aged 5-15 years participated in an intervention delivered to schools in two phases, along with a third phase receiving the intervention after the evaluation, which served as a control. The primary outcome was the number of face washing events that took place when handwashing occurred, which was measured by a 3-hour structured observation at all 67 schools, and a total of 3,871 handwashing events were observed. Differences in observed in face washing behavior between each phase and the control schools were calculated using log-binomial regression with clustering at the school level, whereas survey responses on knowledge of trachoma transmission and prevention were compared using χ2 tests adjusted for clustering at the school level. Face washing during handwashing events was higher in schools after 12 months (59.3%) and 20 months (44.2%) than in control schools (18.7%, P < 0.001). Trachoma knowledge was higher in schools evaluated after 12 months (80%) and 20 months (70%) than in control schools (42%, P < 0.001), and knowledge of some of key preventive behaviors was higher in intervention schools. Integrating face washing messages into school-based handwashing promotion programs increased face washing, which may help to prevent trachoma when combined with other interventions.

Effect of Two Complementary Mass-Scale Media Interventions on Handwashing with Soap among Mothers.

Poor handwashing behavior is a major cause of morbidity and mortality globally. We evaluated two complementary mass-scale media interventions targeting mothers to increase the frequency of handwashing with soap; one using TV advertising, and the other mobile phone messaging. Television Commercials (TVCs): Mothers of 4-12 year-old children (n = 756) were randomly allocated among four arms: Three different branded TVCs and a fourth, control TVC unrelated to handwashing. TVCs were embedded in blocks of unrelated commercials and shown once a week over four weeks in participants' own homes. Mobile messages: New mothers (n = 598) and mothers of 4-7 year-old children (n = 501) were enrolled in a treatment or control arm. Mothers in the treatment arm received branded mobile phone messages twice weekly for 8 weeks (new mothers) or 4 weeks (mothers of 4-7 year-olds). For TVCs, there were higher rates of handwashing with soap at key occasions in the first (RR: 1.33, p = .002) and second (RR: 1.26, p = .041) of three treatment arms, or 0.4 additional handwashes with soap on key occasions daily. In the mobile study, new mothers (adj-RR: 1.04, p = .035) and general mothers (RR: 1.07, p = .007) receiving the intervention were more likely to wash their hands with soap on key occasions than those in the control group, corresponding to 1.3 and 1.0 more occasions daily. These interventions were associated with significantly greater handwashing with soap, consistent with the hypothesis that branded mass communications can impact habitual lifestyle behaviors relevant to public health.

The effect of the "Follow in my Green Food Steps" programme on cooking behaviours for improved iron intake: a quasi-experimental randomized community study.

BACKGROUND: Nutritional iron deficiency is one of the leading factors for disease, disability and death. A quasi-experimental randomized community study in South-West Nigeria explored whether a branded behaviour change programme increased the use of green leafy vegetables (greens) and iron-fortified bouillon cubes in stews for improved iron intake. METHODS: A coinflip assigned the intervention to Ile-Ife (Intervention town). Osogbo (Control town) received no information. At baseline 602 mother-daughter pairs (daughters aged 12-18) were enrolled (Intervention: 300; Control: 302). A Food Frequency Questionnaire assessed the addition of cubes and greens to stews, the primary outcome. Secondary outcomes were the addition of cubes and greens to soups and changes in behavioural determinants measured using the Theory of Planned Behaviour. Structural Equation Modelling (SEM) evaluated the impact of the intervention on behavioural determinants and behaviour. RESULTS: The data of 527 pairs was used (Intervention: 240; Control: 287). The increase in greens added to stews was larger in the Intervention town compared to the Control town (MIntervention = 0.3 [SE = 0.03]; MControl = 0.0 [SE = 0.04], p < 0.001, r = 0.36). Change in iron-fortified cubes added to stews did not differ between towns (p = 0.07). The increase in cubes added to soups was larger in the Intervention town compared to the Control Town (MIntervention = 0.9 [SE = 0.2] vs MControl = 0.4 [SE = 0.1], p < .0001, r = 0.20). Unexpectedly, change in greens added to soups was larger in the Control town compared to the Intervention town (MIntervention = - 0.1 [SE = 0.1]; MControl = 0.5 [SE = 0.1], p = 0.003, r = 0.15). The intervention positively influenced awareness of anaemia and the determinants of behaviour in the Intervention town, with hardly any change in the Control town. Baseline SEMs could not be established, so no mediation analyses were done. Post-intervention SEMs highlighted the role of habit in cooking stews. CONCLUSIONS: The behaviour change programme increased the amount of green leafy vegetables added to stews and iron-fortified cubes added to soups. Future research should assess the long-term impact and the efficacy of the programme as it is scaled up and rolled out.

Use of Electronic Loggers to Measure Changes in the Rates of Hand Washing with Soap in Low-Income Urban Households in India.

We evaluated the utility of electronic loggers to measure the effects of a simple intervention designed to influence the rates of hand washing with soap within enclosed toilets and bathrooms in low-income urban households in Kerala, India. 58 households were given three items with embedded electronic loggers for a period of 2-5 days. Two logged soaps tracked hand and body washing in the bathroom. The third logged item was a water vessel used for flushing the toilet and for post-defecation anal cleansing; this served as a marker of toilet use. In addition, 28 households in a Soap by toilet arm were given an additional logged soap, to be kept by the toilet, and used for hand washing. Compared with the Soap in bathroom arm, the loggers in the Soap by toilet households recorded 73% greater daily use of soaps designated for hand washing (t(36)=2.92, p<0.01) and 172% greater use within 2 minutes of the use of the water vessel (t(36)=3.51, p = 0.001). We conclude that the loggers were capable of detecting changes in the rates of hand washing with soap and changes in hand washing with soap after use of the toilet. Further adoption of logger technologies would enable more insightful studies of hand washing within urban environments.

An investigation of the effects of a hand washing intervention on health outcomes and school absence using a randomised trial in Indian urban communities.

OBJECTIVES: To evaluate how an intervention, which combined hand washing promotion aimed at 5-year-olds with provision of free soap, affected illnesses among the children and their families and children's school absenteeism. METHODS: We monitored illnesses, including diarrhoea and acute respiratory infections (ARIs), school absences and soap consumption for 41 weeks in 70 low-income communities in Mumbai, India (35 communities per arm). RESULTS: Outcomes from 847 intervention households (containing 847 5-year-olds and 4863 subjects in total) and 833 control households (containing 833 5-year-olds and 4812 subjects) were modelled using negative binomial regression. Intervention group 5-year-olds had fewer episodes of diarrhoea (-25%, 95% confidence intervals [CI] = -37%, -2%), ARIs (-15%, 95% CI = -30%, -8%), school absences due to illnesses (-27%, 95% CI = -41%, -18%) and eye infections (-46%, 95% CI = -58%, -31%). Further, there were fewer episodes of diarrhoea and ARIs in the intervention group for 'whole families' (-31%, 95% CI = -37%, -5%; and -14%, 95% CI = -23%, -6%, respectively), 6- to 15-year-olds (-30%, 95% CI = -39%, -7%; and -15%, 95% CI = -24%, -6%) and under 5 s (-32%, 95% CI = -41%, -4%; and -20%, 95% CI = -29%, -8%). CONCLUSIONS: Direct-contact hand washing interventions aimed at younger school-aged children can affect the health of the whole family. These may be scalable through public-private partnerships and classroom-based campaigns. Further work is required to understand the conditions under which health benefits are transferred and the mechanisms for transference.

Behaviour change for better health: nutrition, hygiene and sustainability.

As the global population grows there is a clear challenge to address the needs of consumers, without depleting natural resources and whilst helping to improve nutrition and hygiene to reduce the growth of noncommunicable diseases. For fast-moving consumer goods companies, like Unilever, this challenge provides a clear opportunity to reshape its business to a model that decouples growth from a negative impact on natural resources and health. However, this change in the business model also requires a change in consumer behaviour. In acknowledgement of this challenge Unilever organised a symposium entitled 'Behaviour Change for Better Health: Nutrition, Hygiene and Sustainability'. The intention was to discuss how consumers can be motivated to live a more healthy and sustainable lifestlye in today's environment. This article summarises the main conclusions of the presentations given at the symposium. Three main topics were discussed. In the first session, key experts discussed how demographic changes - particularly in developing and emerging countries - imply the need for consumer behaviour change. The second session focused on the use of behaviour change theory to design, implement and evaluate interventions, and the potential role of (new or reformulated) products as agents of change. In the final session, key issues were discussed regarding the use of collaborations to increase the impact and reach, and to decrease the costs, of interventions. The symposium highlighted a number of key scientific challenges for Unilever and other parties that have set nutrition, hygiene and sustainability as key priorities. The key challenges include: adapting behaviour change approaches to cultures in developing and emerging economies; designing evidence-based behaviour change interventions, in which products can play a key role as agents of change; and scaling up behaviour change activities in cost-effective ways, which requires a new mindset involving public-private partnerships.
