RESUMO

INTRODUCTION: Tobacco production continues to increase in low- and middle-income countries creating complications for tobacco control efforts. There is the need to understand and address the global tobacco leaf supply as a means of decreasing tobacco consumption and improving farmers livelihoods in line with Article 17 of the WHO Framework Convention on Tobacco Control. This study aims to understand the reasons why farmers grow tobacco and identify factors that influence these reasons. METHODS: Primary survey data (N = 1770) collected in Kenya, Malawi, and Zambia in the 2013-2014 farming season. Data analysis uses both descriptive and multinomial logistical regression methods. RESULTS: Majority of farmers started and are currently growing tobacco because they believed it was the only economically viable crop. Compared with Malawi, farmers in Kenya and Zambia have a 0.2 and 0.4 lower probability of growing tobacco, respectively because they perceive it as the only economically viable crop, but a 0.04 and 0.2 higher probability of growing tobacco, respectively because they believe it is highly lucrative. There are district/county differences in the reasons provided with some districts having a majority of the farmers citing the existence of a ready market or incentives from the tobacco industry. Statistically significant factors influencing these reasons are the educational level and age of the household head, land allocated to tobacco and debts. CONCLUSION: There is the need to address the unique features of each district to increase successful uptake of alternative livelihoods. One consistent finding is that farmers' perceived economic viability contributes to tobacco growing. IMPLICATIONS: This study finds that perceived economic viability of tobacco is the dominant factor in the decisions to grow tobacco by smallholder farmers in Malawi, Kenya, and Zambia. There is the need to more deeply understand what contributes to farmers' perceived viability of a crop. Understanding and addressing these factors may increase the successful uptake of alternative livelihoods to tobacco. Furthermore, this study demonstrates that a one-size fits all alternative livelihood intervention is less likely to be effective as each district has unique features affecting farmers' decisions on growing tobacco.

RESUMO

BACKGROUND: The tobacco industry has used the alleged negative impacts on economic livelihoods for tobacco farmers as a narrative to oppose tobacco control measures in low/middle-income countries. However, rigorous empirical evidence to support or refute this claim remains scarce. Accordingly, we assess how much money households earn from selling tobacco, and the costs they incur to produce the crop, including labour inputs. We also evaluate farmers' decision to operate under contract directly with tobacco manufacturers and tobacco leaf-buying companies or to operate as independent farmers. METHODS: A stratified random sampling method was used to implement a nationally representative household-level economic survey of 585 farmers across the three main tobacco growing regions in Kenya. The survey was augmented with focus group discussions in all three regions to refine and enrich the context of the findings. RESULTS: Both contract and independent farmers experience small profit margins per acre, with contract farmers operating at a loss. Even when family labour is excluded from the calculation, income levels remain low, particularly considering the typically large households. Generally, tobacco farmers enter into contracts with tobacco companies because they have a 'guaranteed' buyer for their tobacco leaf and receive the necessary agricultural inputs (fertiliser, seeds, herbicides and so on) without paying cash up-front. CONCLUSIONS: Tobacco farming households enter into contract with tobacco companies to realise perceived economic benefits. The narrative that tobacco farming is a lucrative economic undertaking for smallholder farmers, however, is inaccurate in the context of Kenya.

RESUMO

BACKGROUND: Tobacco production is said to be an important contributor to Zambia's economy in terms of labour and revenue generation. In light of Zambia's obligations under the WHO Framework Convention of Tobacco Control (FCTC) we examined the institutional actors in Zambia's tobacco sector to better understand their roles and determine the institutional context that supports tobacco production in Zambia. METHODS: Findings from 26 qualitative, semi-structured individual or small-group interviews with key informants from governmental, intergovernmental and non-governmental organisations were analysed, along with data and information from published literature. RESULTS: Although Zambia is obligated under the FCTC to take steps to reduce tobacco production, the country's weak economy and strong tobacco interests make it difficult to achieve this goal. Respondents uniformly acknowledged that growing the country's economy and ensuring employment for its citizens are the government's top priorities. Lacklustre coordination and collaboration between the institutional actors, both within and outside government, contributes to an environment that helps sustain tobacco production in the country. A Tobacco Products Control Bill has been under review for a number of years, but with no supply measures included, and with no indication of when or whether it will be passed. CONCLUSIONS: As with other low-income countries involved in tobacco production, there is inconsistency between Zambia's economic policy to strengthen the country's economy and its FCTC commitment to regulate and control tobacco production. The absence of a whole-of-government approach towards tobacco control has created an institutional context of duelling objectives, with some government ministries working at cross-purposes and tobacco interests left unchecked. With no ultimate coordinating authority, this industry risks being run according to the desire and demands of multinational tobacco companies, with few, if any, checks against them.

RESUMO

BACKGROUND: The preservation of the economic livelihood of tobacco farmers is a common argument used to oppose tobacco control measures. However, little empirical evidence exists about these livelihoods. We seek to evaluate the economic livelihoods of individual tobacco farmers in Malawi, including how much money they earn from selling tobacco, and the costs they incur to produce the crop, including labour inputs. We also evaluate farmers' decisions to contract directly with firms that buy their crops. METHODS: We designed and implemented an economic survey of 685 tobacco farmers, including both independent and contract farmers, across the 6 main tobacco-growing districts. We augmented the survey with focus group discussions with subsets of respondents from each region to refine our inquiries. RESULTS: Contract farmers cultivating tobacco in Malawi as their main economic livelihoods are typically operating at margins that place their households well below national poverty thresholds, while independent farmers are typically operating at a loss. Even when labour is excluded from the calculation of income less costs, farmers' gross margins place most households in the bottom income decile of the overall population. Tobacco farmers appear to contract principally as a means to obtain credit, which is consistently reported to be difficult to obtain. CONCLUSIONS: The tobacco industry narrative that tobacco farming is a lucrative economic endeavour for smallholder farmers is demonstrably inaccurate in the context of Malawi. From the perspective of these farmers, tobacco farming is an economically challenging livelihood for most.

RESUMO

PURPOSE: Policy misalignment across different sectors of government serves as one of the pivotal barriers to WHO Framework Convention on Tobacco Control (FCTC) implementation. This paper examines the logic used by government officials to justify investment incentives to increase tobacco processing and manufacturing in the context of FCTC implementation in Zambia. METHODS: We conducted qualitative semistructured interviews with key informants from government, civil society and intergovernmental economic organisations (n=23). We supplemented the interview data with an analysis of public documents pertaining to the policy of economic development in Zambia. RESULTS: We found gross misalignments between the policies of the economic sector and efforts to implement the provisions of the FCTC. Our interviews uncovered the rationale used by officials in the economic sector to justify providing economic incentives to bolster tobacco processing and manufacturing in Zambia: (1) tobacco is not consumed by Zambians/tobacco is an export commodity, (2) economic benefits outweigh health costs and (3) tobacco consumption is a personal choice. CONCLUSIONS: Much of the struggle Zambia has experienced in implementing the FCTC can be attributed to misalignments between the economic and health sectors. Zambia's development agenda seeks to bolster agricultural processing and manufacturing. Tobacco control proponents must recognise and work within this context in order to foster productive strategies with those working on tobacco supply issues. These findings are broadly applicable to the global context. It is important that the Ministry of Health monitors the tobacco policy of and engages with these sectors to find ways of harmonising FCTC implementation.

RESUMO

OBJECTIVES: Little is known about cigarette pricing and brand loyalty in sub-Saharan Africa. This study examines these issues in Zambia, analysing data from the International Tobacco Control (ITC) Zambia Survey. METHODS: Data from Wave 1 of the ITC Zambia Survey (2012) were analysed for current smokers of factory-made (FM) cigarettes compared with those who smoked both FM and roll-your-own (RYO) cigarettes, using multivariate logistic regression models to identify the predictors of brand loyalty and reasons for brand choice. RESULTS: 75% of FM-only smokers and 64% of FM+RYO smokers reported having a regular brand. Compared with FM-only smokers, FM+RYO smokers were, on average, older (28% vs 20% ≥40 years), low income (64% vs 43%) and had lower education (76% vs 44% < secondary). Mean price across FM brands was ZMW0.50 (US$0.08) per stick. Smokers were significantly less likely to be brand loyal (>1 year) if they were aged 15-17 years (vs 40-54 years) and if they had moderate (vs low) income. Brand choice was predicted mostly by friends, taste and brand popularity. Price was more likely to be a reason for brand loyalty among FM+RYO smokers, among ≥55-year-old smokers and among those who reported being more addicted to cigarettes. CONCLUSIONS: These results in Zambia document the high levels of brand loyalty in a market where price variation is fairly small across cigarette brands. Future research is needed on longitudinal trends to evaluate the effect of tobacco control policies in Zambia.

RESUMO

BACKGROUND: Nicotine replacement therapy (NRT) and short messaging service (SMS)-based tobacco cessation interventions have demonstrated effectiveness in reducing tobacco use in many populations, but evidence is needed on which tailored treatments are most efficacious in meeting the complex medical and psychosocial factors confronting people living with HIV (PLWH) in sub-Saharan Africa (SSA). This paper describes the protocol of a study to test the efficacy of both NRT and a tailored SMS-based tobacco use cessation intervention among PLWH in Uganda and Zambia. METHODS: In a randomized controlled trial, 800 adult PLWH who use tobacco will be recruited by health care professionals at HIV treatment centers where they are receiving care. Participants will be randomized to one of the four study arms: (1) standard of care [SOC; brief clinician advice to quit combined with HIV education and information aimed at encouraging HIV treatment adherence (with no mention of tobacco) delivered via text messages]; (2) SOC + 12 weeks of NRT; (3) SOC + 6 weeks of SMS text messages to support quitting tobacco use (SMS); or (4) SOC + NRT + SMS. Participants will receive a cell phone and solar panel with power bank for charging the phone. The main outcome is cessation of tobacco use by study participants verified by urinary cotinine (< 15 ng/mL) at 6 months post-enrollment. As a secondary tobacco use outcome, we will measure 7-day point-prevalence abstinence (7 consecutive days of no tobacco use) measured by self-report and biochemically-verified at 4 weeks, 8 weeks, and 3 months post enrollment. DISCUSSION: Our study will provide insight into the efficacy, feasibility and applicability of delivering tobacco cessation interventions through health care professionals combined with tailored tobacco cessation SMS text messaging in two countries with different tobacco use patterns, policy environments, and health care resources and provide needed information to providers and policymakers looking for cost-effective tobacco cessation interventions. The previously tested SMS-platform to be used in our study is uniquely positioned to be scaled in low- and middle-income countries worldwide, in which case evidence of even modest success in reducing the prevalence of tobacco consumption among PLWH could confer enormous health and economic benefits.

RESUMO

OBJECTIVES: To examine the prevalence of hypertension and access to related healthcare services among rural residents of Mumbwa district in Zambia. DESIGN: Cross-sectional study with probability cluster sampling. SETTING: Rural Zambia. PARTICIPANTS: We recruited 690 residents from Mumbwa district aged 25-64 years who had been living in the study area for ≥6 months and had adopted the lifestyle of the study area. Pregnant women and women who had given birth in the past 6 months were excluded. The data collection-questionnaire survey and anthropometric and biological measurements-was conducted between May and July 2016. RESULTS: In the overall sample, 39.7% and 33.5% of the men and women had hypertension (systolic blood pressure (BP)≥140 or diastolic BP ≥90 mm Hg), respectively. Among the participants without a previous diagnosis of hypertension, 30.3% presented with hypertension at the time of measurement. In the multivariable analysis, alcohol intake and urban residence in men, and older age group, higher education and body mass index ≥25 kg/m2 in women were significantly associated with hypertension. Among the 21.8% who never had their BP measured, 83.8% were men; among these men, older age (adjusted OR (AOR), 0.43; 95% CI 0.25 to 0.73) and HIV positive status (AOR, 0.37; 95% CI 0.14 to 0.97) were negatively associated, while current smoker status (AOR, 2.09; 95% CI 1.19 to 3.66) was positively associated with the lack of BP measurements. CONCLUSION: We found that hypertension is prevalent in the target rural area. However, many were not aware of their hypertension status and many never had their BP measured, indicating a serious gap in cardiovascular disease prevention services in Zambia. There is an urgent need for health promotion and screening for hypertension, especially in the primary health services of rural Zambia. Issues related to healthcare accessibility in men require particular attention.

RESUMO

Zambia, a tobacco-growing country, provides manufacturing incentives to attract foreign and domestic investment. In an earlier study, we cautioned that these incentives could lead to local tobacco manufacturing, undermining its domestic tobacco control efforts. In 2018, as part of our continuing research program, we conducted key informant interviews (n = 15) and document analyses. Our early caution proved correct. In 2018, taking advantage of tax incentives, British American Tobacco Zambia and Roland Imperial Tobacco opened new cigarette-manufacturing facilities in the Lusaka Multi-Facility Economic Zone. They report capability of producing 25 million cigarettes daily, between 3 and 5 million of which is intended for the domestic market. Zambia's tax incentives for cigarette manufacturing are likely to increase domestic consumption. The 170 new jobs created in the two plants pale when considering long-term health impacts and lost economic productivity of an increase in supply of locally produced cigarette brands.

RESUMO

BACKGROUND: Cardiovascular diseases are among the leading causes of mortality and morbidity in sub-Saharan Africa, including Zambia, where cardiovascular diseases account for 8% of the mortality rates. Despite an increasing number of cardiovascular disease-related studies in Zambia, qualitative studies exploring how cardiovascular diseases and their risk factors are understood in the socioeconomic and cultural contexts are still few. This study, therefore, aimed to analyze the beliefs, perceptions, and behaviors related to cardiovascular diseases and their risk factors among the local residents of Zambia. METHODS: This qualitative study was conducted from August to September 2014 among healthy residents aged 40 years and above in a rural community in Mumbwa District. We investigated the beliefs, perceptions, and behaviors related to cardiovascular diseases and their potential risk factors in the sociocultural context of Zambia by conducting in-depth interviews and focus group interviews. Audio-recorded interviews were transcribed and analyzed using thematic analysis with investigator triangulation. RESULTS: We conducted 34 in-depth interviews and 6 focus group interviews with 27 males and 40 females. Most participants were aware of the prevalence of cardiovascular diseases around them and correctly identified hypertension, excessive salt, sugar, and cooking oil intakes, poor quality cooking oil, consumption of meat or vegetables contaminated with chemicals, obesity, stress ["thinking too much"], lack of physical exercise, and heredity as potential risk factors of cardiovascular diseases, while smoking and alcohol were mentioned by only a few participants. However, they claimed that many of these risk factors were difficult to avoid due to ingrained taste preferences for high salt and sugar, increasingly busy lives that force them to use cooking oil to reduce preparation time, cultural preference for big body size or fatness, especially for women, stigmatized body image attached to HIV, stressful life or life events related to poverty, and financial barriers to affording quality foods and healthcare services. Limited health screening opportunities and the negative impact of HIV-related stigma on health-seeking behavior also emerged as important risk factors for cardiovascular diseases. CONCLUSIONS: This study revealed that participants are relatively well aware of cardiovascular diseases and their risk factors. However, they engage in high-risk health behaviors, due to ingrained taste preferences, limited knowledge, and unavoidable socioeconomic and cultural circumstances. Results suggest that prevention interventions addressing cardiovascular diseases in rural Zambia should target gaps in knowledge and socioeconomic and cultural barriers.

RESUMO

Tobacco control norms have gained momentum over the past decade. To date 43 of 47 Sub-Saharan African countries are party to the Framework Convention on Tobacco Control (FCTC). The near universal adoption of the FCTC illustrates the increasing strength of these norms, although the level of commitment to implement the provisions varies widely. However, tobacco control is enmeshed in a web of international norms that has bearing on how governments implement and strengthen tobacco control measures. Given that economic arguments in favor of tobacco production remain a prominent barrier to tobacco control efforts, there is a continued need to examine how economic sectors frame and mobilize their policy commitments to tobacco production. This study explores the proposition that divergence of international norms fosters policy divergence within governments. This study was conducted in three African countries: Kenya, Malawi, and Zambia. These countries represent a continuum of tobacco control policy, whereby Kenya is one of the most advanced countries in Africa in this respect, whereas Malawi is one of the few countries that is not a party to the FCTC and has implemented few measures. We conducted 55 key informant interviews (Zambia = 23; Kenya = 17; Malawi = 15). Data analysis involved deductive coding of interview transcripts and notes to identify reference to international norms (i.e. commitments, agreements, institutions), coupled with an inductive analysis that sought to interpret the meaning participants ascribe to these norms. Our analysis suggests that commitments to tobacco control have yet to penetrate non-health sectors, who perceive tobacco control as largely in conflict with international economic norms. The reasons for this perceived conflict seems to include: (1) an entrenched and narrow conceptualization of economic development norms, (2) the power of economic interests to shape policy discourses, and (3) a structural divide between sectors in the form of bureaucratic silos.

RESUMO

BACKGROUND: Sub-Saharan Africa, including Zambia, has experienced an increase in overweight and obesity due to rapid lifestyle changes associated with recent economic growth. We explored the prevalence and correlates of overweight and obesity in rural Zambia. We also investigated the role of self-perception of body weight in weight control given the local socio-cultural context. METHODS: In this cross-sectional study, we recruited 690 residents of the Mumbwa district aged 25-64 years through a multistage, clustered, household random sampling. We administered a questionnaire and collected anthropometric and bio-behavioral data from May to July 2016. Factors associated with body mass index (BMI) ≥25 kg/m2 and underestimation of body weight were assessed using multiple logistic regression. RESULTS: Of the weighted sample of 689 participants (335 men and 354 women), 185 (26.8%) had BMI ≥25 kg/m2. In multivariate analyses, female gender, age 45-64 years, tertiary education, higher fruit and vegetable intake, high blood pressure, abnormal blood lipid profile, and Hemoglobin A1c ≥5.7% were significantly associated with BMI ≥25 kg/m2. Among participants with BMI ≥25 kg/m2, 14.2% and 58.2% perceived themselves as being underweight and normal weight, respectively. Age 45-64 years was the only factor significantly associated with body weight underestimation. Preference for obesity was reported by 17.5% and 3.6% of respondents with BMI <25 kg/m2 and BMI≥25 kg/m2, respectively; "looks attractive" and "fear of being perceived as HIV-positive" were the main reasons. CONCLUSION: In rural Zambia, overweight and obesity are prevalent and significantly associated with alterations in blood pressure, blood lipid profile, and glucose metabolism. However, most subjects with BMI ≥25 kg/m2 underestimated their body weight; some preferred obesity, in part due to cultural factors and HIV-related stigma. A health promotion program that addresses such perceptions and body weight underestimation should be urgently introduced in Zambia.

RESUMO

BACKGROUND: Tobacco use is the leading cause of noncommunicable disease morbidity and mortality. Most smokers initiate the smoking habit as adolescents or young adults. METHODS: Survey data from the 2007 Lusaka (Zambia) Global Youth Tobacco Survey were used to estimate the prevalence of current cigarette smoking and assess whether exposure to pro-tobacco media and perception of the potential harm of secondhand smoke are associated with adolescents' smoking. Logistic regression analysis was used to estimate the associations. RESULTS: Altogether, 2378 students, of whom 56.8% were females, participated in the study. Overall, 10.5% of the students (9.3% among males and 12.1% among females) smoked cigarettes in the 30 days prior to the survey. Students who favored banning smoking in public places were 33% (OR = 0.67; 95% CI [0.47, 0.96]) less likely to smoke cigarettes compared to those who were not in favor of the ban. Seeing actors smoking in TV shows, videos or movies was positively associated with smoking (OR = 1.90; 95% CI [1.26, 2.88]). However, possessing an item with a cigarette brand logo on it, seeing advertisements of cigarettes on billboards and being ever offered a free cigarette by a cigarette sales representative were negatively associated with smoking (OR=0.39, 95% CI [0.26, 0.58]; OR=0.63, 95% CI [0.43, 0.92]; and OR=0.43, 95% CI [0.29, 0.65], respectively). CONCLUSION: Findings from this study indicate that TV advertisement-promotion-sponsorship was positively associated with smoking, while it was the opposite with other forms of advertisement; there is a need for further studies.
