High prevalence and clustering of modifiable CVD risk factors among rural adolescents in southwest Nigeria: implication for grass root prevention

Co-occurrence of non-communicable disease risk factors among adolescents in Jos, Nigeria

BACKGROUND

The co-occurrence and clustering of risk factors for non-communicable disease (NCD) is a global public health concern.

AIM

This study aimed to assess the co-occurrence and clustering of risk factors for NCDs among in-school and out-of-school adolescents in Jos North Local Government Area, Plateau State, Nigeria.

SETTING

Secondary schools and markets in Jos North Local Government Area.

METHODS

A comparative cross-sectional study was conducted among 377 in-school and 377 out-of-school adolescents, aged 10-19 years of age. An interviewer-administered questionnaire was used to collect information on behavioural and physical risk factors for NCDs. Chi-square and Mann-Whitney U tests were used for comparisons at a 5% level of significance. Statistical analysis was carried out using Statistical Product and Service Solutions (SPSS) version 23.0.

RESULTS

Of the 754 sampled adolescents, 386 (51.2%) were females and 368 (48.8%) were males. Adolescents aged 10-14 years made up 37.8% of the participants, 15 to 17 years of age accounted for 46.9% and 18-19 years 15.3%. Risk factors with the highest prevalence were a sedentary lifestyle (94.2%) and an unhealthy diet (92.4%). Majority (97.2%) had two or more risk factors while 1.9% of adolescents had no risk factor. More in-school adolescents (24.1%) had two risk factors compared to 14.1% of out-of-school adolescents (p 0.001); 14.1% of out-of-school adolescents had five or more risk factors compared to 2.9% of those in school (p 0.001).

CONCLUSION

Co-occurrence and clustering of behavioural and physical risk factors was found among both in-school and out-of-school adolescents.Contribution: This study highlighted the burden of risk factors for NCDs among both in-school and out-of-school adolescents in the North-Central part of Nigeria. This is especially useful in developing targeted interventions to tackle these risk factors.

Self-reported cardiovascular disease risk factor screening among people living with HIV vs. members of the general population in Botswana: a community-based study

BACKGROUND

Morbidity and mortality due to cardiovascular diseases (CVDs) are high and increasing in low- and middle-income countries. People living with HIV (PLWH) are more likely to experience CVD than members of the general population. Therefore, we aimed to assess whether PLWH were more likely to have previously been screened for cardiovascular disease risk factors (CVDRFs) than people without HIV.

METHODS

A population-based, cross-sectional study was conducted among individuals aged 16 to 68 years across 22 communities in Botswana from February to August 2017 as part of a larger community-based cluster randomized HIV treatment-as-prevention trial. Participants were asked if they had been screened for and counselled on cardiovascular disease risk factors (history of hypertension or blood pressure check, blood glucose and cholesterol measurements, weight check and weight control, tobacco smoking and cessation, alcohol use and physical activity) in the preceding 3 years. HIV testing was offered to those with an unknown HIV status. Multiple logistic regression analysis controlling for age and sex was used to assess the relationship between CVDRF screening and HIV status.

RESULTS

Of the 3981 participants enrolled, 2547 (64%) were female, and 1196 (30%) were PLWH (93% already on antiretroviral therapy [ART]). PLWH were more likely to report previous screening for diabetes (25% vs. 19%, p < 0.001), elevated cholesterol (17% vs. 12%, p < 0.001) and to have had their weight checked (76% vs. 55%, p < 0.001) than HIV-uninfected participants. PLWH were also more likely to have received counselling on salt intake (42% vs. 33%, p < 0.001), smoking cessation (66% vs. 46%, p < 0.001), weight control (38% vs. 29%, p < 0.001), physical activity (46% vs. 34%, p < 0.001) and alcohol consumption (35% vs. 23%, p < 0.001) than their HIV-uninfected counterparts. Overall, PLWH were more likely to have received screening for and/or counselling on CVDRFs (adjusted odds ratio 1.84, 95% CI: 1.46-2.32, p < 0.001).

CONCLUSION

PLWH were almost two times more likely to have been previously screened for CVDRFs than those without HIV, indicating a need for universal scale-up of integrated management and prevention of CVDs in the HIV-uninfected population.

Sex for food: a transactional sex reaction to the COVID-19-induced rise in the prevalence of hunger among in-school female adolescents in Ogun State, Nigeria

Introduction

COVID-19 has doubled the proportion of people with acute hunger globally and Nigeria is categorized as having a "severe" form of hunger. Vulnerable groups responding more to hunger stressors include the female adolescents who transact sex for both survival and luxury purposes. This study assessed the engagement in transactional sex to obtain food among female adolescents in Ogun State, Nigeria.

Methods

this descriptive cross-sectional research was conducted among 668 in-school female adolescents that were selected through a multistage sampling method. Data were collected with a structured interviewer-administered questionnaire. Food security was assessed using a standard tool while engagement in transactional sex was elicited through self-report. Data analysis was done using Statistical package for the social sciences (SPSS) version 25. Logistic regression was used to find factors associated with transactional sex. P< 0.05 was taken as statistically significant.

Results

the mean age of the respondents was 15.18±1.35 years. More than two-fifths (41.5%) were staying in households without food security. Less than one-fifth (15.3%) were engaging in transactional sex. Having emotional stress (OR = 4.33; 95 CI: 1.37-13.63), mother´s education (OR =0.163; 95% CI: 0.057- 0.461), having sexual partner (OR = 0.132; 95% CI: 0.047-0.370 and missing classes (OR 3.35, 95% CI: 1.084-10.331) were significant predictors of engaging in transactional sex among female adolescents.

Conclusion

transactional sex is commoner among female adolescents who were missing classes, had sexual partners, and were emotionally stressed. There is a need for intervention programs to protect the female adolescent, delay sexual debut and improve academic performance among them.

A School-based survey among adolescents on Dietary pattern, Exercise, and Knowledge of Cardiovascular risk factors (ADEK) Study

Background. Cardiovascular disease is a global emerging problem and its risk starts in children and adolescents. Adolescents have modifiable cardiovascular risk factors that have been found globally, and nationally, and early intervention programs may be able to lower these risks for both individuals and populations. Accurate risk factor evaluation at the individual level is crucial in this situation for the prevention of cardiovascular disease. Objective. The study aimed to investigate cardiovascular disease knowledge and to determine physical activity, and dietary patterns among school-going adolescents in Arakkonam, Tamil Nadu, India. Methods. A school-based cross-sectional survey was conducted to assess cardiovascular disease knowledge among 500 adolescents aged 10-18 from public schools. The study period was from September 2021 to February 2022. The measurement taken on anthropometrics such as height, weight, body mass index, and bio-physiological measurement as blood pressure, structured questionnaire assessed for knowledge, dietary questionnaire assessed previous week food consumption which the investigator developed, and physical activity standard questionnaire assessed the past week’s exercise level. Data were analyzed using IBM Statistical Package for Social Sciences version 20. Results. The mean study population age was 13.7±1.7, 53% were boys, and 47% were girls. Factors like age 16-18 years (p=0.01), site of residence from urban (p=0.001), education of teenagers (p=0.01), and family history of cardiovascular disease (p=0.001) are significantly correlated with the level of knowledge score, with better-educated adolescents having fair knowledge score than others. Level of knowledge score and demographic traits are associated with physical activity, such as 16 to 18 years (p=0.03), living in an urban region (p=0.03), being in a joint household (p=0.001), adolescents who are at higher secondary (p=0.02), and having a family history contribute more to cardiovascular disease (p=0.001) than other variables. Mean days eating diets were egg (4.18±2.27), vegetables (3.92±0.93), milk products (3.85±1.87), fried foods (3.75±1.25), toffees, and chocolates (3.35±1.81) all had higher percentages of consumed foods than others. Conclusion: There is a risk of cardiovascular disease higher among adolescents. Still a need for school-based primordial preventive educational approaches needed to improve to curb this burden.

Effectiveness of structured interventional strategy for middle-aged adolescence (SISMA-PA) for preventing atherosclerotic risk factors—A study protocol

Background

Atherosclerotic risk starts at an early stage in adolescents and interventions on adolescents’ lifestyles are most important. The pandemic of obesity-related morbidities like atherosclerosis among young adults and atherosclerotic risk factors for middle-aged adolescents in India is known. Yet, there is a lack of cost-effective and integrated intervention programs to treat this important health problem.

Objective

The main objective of this study is to evaluate the effect of a 12-week structured interventional strategy program, containing integrated education and supervised physical activity interventions for middle-aged adolescents.

Methods/design

This will be a school-based pre-experimental one-group pre-post time-series research design. The sample size is estimated to include 154 adolescents of 10^th to 12^th grade; aged 15–17 years will be grouped as a single arm. Data will be collected from July 2021 to January 2022. The intervention duration will be 3 months. The following measures will be evaluated before, during, and after intervention: knowledge, body mass index, level of physical activity, dietary habits, and sedentary activity.

Discussion

We believe that the structured interventional strategy approach which includes education related to atherosclerosis, physical activity, dietary habits, and sedentary activity, and cost-effective physical activity training will be more effective in preventing atherosclerotic-related changes among middle-aged adolescents. Further, this kind of approach may be applied in similar study areas elsewhere in India.

Temporal trend of simultaneous risk factors for chronic non-communicable diseases: National School Health Survey 2009, 2012, 2015

OBJECTIVE

To analyze the temporal trend of simultaneous occurrence of behavioral risk factors for chronic non-communicable diseases in Brazilian school adolescents.

METHODS

Ecological time-series study that analyzed data from the three editions of the National Survey of School Health with students in the 9th year of public and private schools. Cluster analysis was performed to identify the simultaneity of the following factors: irregular consumption of fresh or minimally processed foods, regular consumption of processed and ultra-processed foods, insufficient level of physical activity during leisure time, consumption of alcoholic beverages, use of cigarettes and illicit drugs. The cluster trend was tested using simple linear regression.

RESULTS

The sample was composed of 173,310 school adolescents. Sixty-four possible combinations were evaluated, resulting in the formation of six clusters. The grouping formed by all factors showed the highest ratios observed/expected prevalence in the last two years of the series. The highest ratios were observed for combinations in which alcohol and cigarettes were present. These substances integrated five of the six clusters. One of the groups (insufficient level of physical activity during leisure time + consumption of alcoholic beverages + use of cigarettes and illicit drugs) had an upward trend throughout the series.

CONCLUSION

The trend analysis showed four out of six clusters remaining stable throughout the series, which shows that the factors are persistently present among school adolescents.

RESUMO: Objetivo: Analisar a tendência temporal da ocorrência simultânea de fatores de risco comportamentais para doenças crônicas não transmissíveis em adolescentes escolares brasileiros. Métodos: Estudo ecológico de série temporal, que analisou os dados das três edições da Pesquisa Nacional de Saúde do Escolar dos alunos do 9º ano de escolas públicas e privadas. Realizou-se a análise de cluster para a identificação da simultaneidade dos seguintes fatores: consumo irregular de alimentos in natura ou minimamente processados, consumo regular de alimentos processados e ultraprocessados, nível insuficiente de atividade física no lazer, consumo de bebidas alcoólicas, uso de cigarro e de drogas ilícitas. A tendência dos clusters foi testada utilizando-se regressão linear simples. Resultados: A amostra constituiu-se de 173.310 escolares. Sessenta e quatro possíveis combinações foram avaliadas, havendo a formação de seis clusters. O agrupamento formado por todos os fatores apresentou as maiores razões entre prevalências observadas e esperadas para os dois últimos anos da série. As maiores razões foram verificadas para as combinações em que estavam presentes o álcool e o cigarro. Além disso, essas substâncias integraram cinco dos seis clusters. Um dos agrupamentos (nível insuficiente de atividade física no lazer + consumo de bebidas alcóolicas + uso de cigarro e drogas ilícitas) apresentou tendência crescente durante toda a série. Conclusão: A análise de tendência constatou que quatro de seis clusters mantiveram-se estáveis durante toda a série, demonstrando que os fatores continuam presentes de forma persistente entre os adolescentes escolares.

Clustering of cardiovascular disease risk factors among first-year students at the University of Ibadan, Nigeria: a cross-sectional study

BACKGROUND

Cardiovascular disease (CVD) is the second leading cause of death in sub-Saharan Africa. Globally, there is substantial evidence that modifiable risk factors for CVD are increasing in adolescents. Unfortunately, there is a paucity of information on the prevalence and clustering of these risk factors in adolescents.

OBJECTIVES

This study explores the modifiable risk factors for CVD among first-year students at the University of Ibadan, Nigeria.

DESIGN AND SETTING

This cross-sectional study was conducted at the University of Ibadan, Nigeria.

METHODS

A total of 546 newly admitted students at the University of Ibadan, Nigeria, were recruited using stratified random sampling. An interviewer-administered questionnaire was used to obtain information from study participants between January and February 2016.

RESULTS

The mean age of respondents was 19 ± 2.2 years with a male-to-female ratio of 1:1. The reported risk factors for CVD were smoking (1.6%), abdominal obesity (3.3%), alcohol consumption (3.7%), overweight/obesity (20.7%), unhealthy diet (85.3%), and physical inactivity (94.5%). Clustering of ≥ 2 risk factors was reported in 23.4% of students. Female students were twice as probably overweight/obese as male students (adjusted odds ratio [AOR] = 2.2; confidence interval [CI] = 1.41-3.43). Students whose fathers were skilled workers were 3.5 times more likely to be physically inactive (AOR = 1.7; CI = 0.97-2.96). The clustering of ≥ 2 risk factors was significantly higher among women and Muslims in bivariate analysis, whereas no significant association was found in multivariate analysis.

CONCLUSIONS

Public health strategies to prevent CVD risk factors should begin in schools and extend to the entire community.

Qualitative views of Nigerian school principals and teachers on the barriers and opportunities for promoting students' physical activity behaviours within the school settings

Background

Insufficient physical activity (PA) is a growing public health challenge among Nigerian adolescents. Significant information gap exists on the school-related factors which influence the participation of adolescents in school-based physical activity programmes in Nigeria. This study was conducted to document the qualitative views of school principals and teachers on the barriers and opportunities for promoting the physical activity behaviours of adolescents within the school settings in light of the socio-ecological model.

Methods

This was a qualitative study conducted in 12 public and private schools in two local government areas of Oyo state, Nigeria. Two key sources and data collection methods (i.e key informant interviews and focus group discussions) were used. Six key informant interviews were held with school principals and six focus group discussions with classroom teachers using pre-tested guides. Data was analysed using thematic analysis.

Results

Fourteen sub-themes were identified as barriers to PA and linked to different levels of the socio-ecological model. Three themes were categorised as parental factors, three themes as socio-cultural and religious factors while the school-related factors had eight sub-themes. Specifically, the school-related barriers were the declining number of trained physical health education teachers, limited opportunities for continuing education and low prioritisation of physical health education. Other school-related factors such as increasing demand for classroom academic time, negative attitudinal dispositions of other teachers and inadequate funding for schools which hampered the provision of facilities and equipment were identified as factors that limit the effective implementation of policies and programmes for physical activity in schools. Opportunities to promote PA within the school settings during assemblies, breaktime, after-school and inter-house sports competition exist. However, these opportunities are hampered by competing academic time, security threats, fear of causalities to students due to poor supervision after school, poor funding and brawling associated with competitive school-based sporting events.

Conclusions

Factors that contribute to insufficient physical activity among in-school adolescents in the school settings are multi-factorial. Implementation of holistic, multi-component interventions which address the social-cultural and school-level factors and enhance students’ opportunities for physical activity in schools are recommended.

Estimating the prevalence of overweight and obesity in Nigeria in 2020: a systematic review and meta-analysis

BACKGROUND

Targeted public health response to obesity in Nigeria is relatively low due to limited epidemiologic understanding. We aimed to estimate nationwide and sub-national prevalence of overweight and obesity in the adult Nigerian population.

METHODS

MEDLINE, EMBASE, Global Health, and Africa Journals Online were systematically searched for relevant epidemiologic studies in Nigeria published on or after 01 January 1990. We assessed quality of studies and conducted a random-effects meta-analysis on extracted crude prevalence rates. Using a meta-regression model, we estimated the number of overweight and obese persons in Nigeria in the year 2020.

RESULTS

From 35 studies (n = 52,816), the pooled crude prevalence rates of overweight and obesity in Nigeria were 25.0% (95% confidence interval, CI: 20.4-29.6) and 14.3% (95% CI: 12.0-15.5), respectively. The prevalence in women was higher compared to men at 25.5% (95% CI: 17.1-34.0) versus 25.2% (95% CI: 18.0-32.4) for overweight, and 19.8% (95% CI: 3.9-25.6) versus 12.9% (95% CI: 9.1-16.7) for obesity, respectively. The pooled mean body mass index (BMI) and waist circumference were 25.6 kg/m2 and 86.5 cm, respectively. We estimated that there were 21 million and 12 million overweight and obese persons in the Nigerian population aged 15 years or more in 2020, accounting for an age-adjusted prevalence of 20.3% and 11.6%, respectively. The prevalence rates of overweight and obesity were consistently higher among urban dwellers (27.2% and 14.4%) compared to rural dwellers (16.4% and 12.1%).

CONCLUSIONS

Our findings suggest a high prevalence of overweight and obesity in Nigeria. This is marked in urban Nigeria and among women, which may in part be due to widespread sedentary lifestyles and a surge in processed food outlets, largely reflective of a trend across many African settings.KEY MESSAGESAbout 12 million persons in Nigeria were estimated to be obese in 2020, with prevalence considerably higher among women. Nutritional and epidemiological transitions driven by demographic changes, rising income, urbanization, unhealthy lifestyles, and consumption of highly processed diets appear to be driving an obesity epidemic in the country.

Towards cardiovascular disease prevention in Nigeria: A mixed method study of how adolescents and young adults in a university setting perceive cardiovascular disease and risk factors

BACKGROUND

Cardiovascular disease (CVD) is a global problem but its increasing prevalence in the working age group in developing countries like Nigeria is concerning and needs urgent attention.

METHODS

The study was a mixed method design: quantitative phase with 402 participants and qualitative phase with 16 participants in two focus groups. The participants in the quantitative survey phase completed two questionnaires on the knowledge and perception of CVD and its risk factors. Data from the quantitative cross-sectional survey were analysed using descriptive and inferential statistics. The qualitative data were analysed using content thematic analysis.

RESULTS

We report that 39.1% of the participants had high knowledge whilst 61.9% had low and average knowledge of CVD and its risk factors. Of the participants, 78.1% had a wrong perception of CVD and its risk factors. Participants from faculties of veterinary medicine and basic medical sciences had better knowledge than others who were not medically inclined (F = 16.11; p 0.001). Only participants from the faculty of veterinary medicine had the right perception of CVD and its risk factors. There was no significant difference in knowledge and perception scores between male and female participants. The qualitative study buttressed the results from the cross-sectional survey, where adolescents and young adults highlighted academic stress and poverty as major risk factors for CVD.

CONCLUSION

Adolescents and young adults in this study did not have good knowledge of CVD and its risk factors. They also had a wrong perception about CVD and its risk factors.

[Behavioral risk factors for cardiovascular diseases in adolescents from the rural area of a municipality in Southern Brazil]

The study aimed to estimate the prevalence of behavioral risk factors for cardiovascular diseases (CVDs) and factors associated with their accumulation in adolescents from the rural area of a municipality in Pelotas, Rio Grande do Sul State, Brazil. This was a cross-sectional school-based census-type study with a sample of 515 sixth to nineth-grade schoolchildren in 21 rural public schools in Pelotas. The target behavioral risk factors were: physical inactivity; irregular consumption of fruits, vegetables, and greens; initiation to alcohol consumption and smoking; and addition of salt to foods. The study outcome was the cluster score of behavioral risk factors, varying from 0 to 3: no behavioral risk factors for CVD or exposure to 1, 2, or ≥ 3 behavioral risk factors. Ordinal logistic regression was performed to assess the effect adjusted for individual characteristics on the accumulation of behavioral risk factors, using as the reference category individuals without any risk factor. Physical inactivity was the most prevalent risk factor (74.8%), followed by irregular consumption of fruits, vegetables, and greens (56.2%). Approximately 42% of the adolescents presented two behavioral risk factors, the most prevalent combination of which was physical inactivity and irregular consumption of fruits, vegetables, and greens (23%). The odds of accumulating two or more behavioral risk factors increased with age. The presence and simultaneity of behavioral risk factors is quite high among adolescents from the rural area of Pelotas, showing that they are exposed to the development of CVD. Interventions are needed to prevent the simultaneous occurrence of these risk factors.

Clustering of Cardiometabolic Risk Factors among Children and Adolescents in a Rural Community in Ondo, Southwest Nigeria

BACKGROUND

Clustering of cardiometabolic risk factors is rapidly becoming prevalent among children and adolescents with grave implications for their cardiovascular health. We set out to determine prevalence and pattern of clustering of risk factors and, identify factors (if any) that determine their clustering.

METHODS

A cross-sectional study of children (3-9 years) and adolescents (10-17 years) in a rural, agrarian community. Their blood pressure, body mass index and lipids were measured. Data was analyzed with SPSS 20.

RESULTS

A total of 114 (M : F, 1 : 1.1) subjects were studied. The mean age of children and adolescents were 5.6 ± 2.1 and 12.9 ± 2.2 years respectively. The most prevalent cardiometabolic risk factors were elevated non-high density lipoprotein-cholesterol (HDL-c; 39.5%), low HDL-c (33.3%), prehypertension (12.3%) and overweight (9.6%). The prevalence of hypertension was higher among females (11.9% vs. 1.8%, p = 0.024) and adolescents (13.2% vs. 1.6%, p = 0.037). Serum levels of non-HDL-c was higher among adolescents than children (50.9% vs. 29.5%, p = 0.013). At least one risk factor was present in 68.4% of the subjects. Clustering of two and three risk factors were present in 18.4% and 6.1%. The presence of prehypertension (χ2 23.93, p < .001), hypertension (χ2 12.19, p = 0.002), high serum non-HDL-c (χ2 6.336, p = 0.011) and high serum total cholesterol (TC; χ2 8.810, p < 0.001) were associated with clustering of cardiometabolic risk factors.

CONCLUSION

The burden of cardiometabolic risk factors among children and adolescents is high. Identified determinants of risk factor clustering were prehypertension, hypertension, non-HDL-c and TC.

Management of pharmacotherapy-related problems in acute coronary syndrome: Role of clinical pharmacist in cardiac rehabilitation unit

Acute coronary syndrome (ACS) is one of the leading causes of mortality worldwide and negatively impacts healthcare costs, productivity and quality of life. Polymorbidity and polypharmacy predispose ACS patients to medication discrepancies between cardiologist-prescribed medication and drug use by the patient, drug-related problems (DRPs) and inadequate drug adherence. This study aimed to evaluate the impact of clinical pharmacist-provided services on the outcome of ACS patients. This was a prospective, randomized, controlled study on ACS patients participating in a cardiac rehabilitation programme. Forty ACS patients were randomly assigned to either control group, who received standard medical care, or intervention group, who received standard medical care plus clinical pharmacist-provided services. Services included DRP management, clinical assessment and enforcing the patient education and adherence. For both groups, the following were assessed at baseline and after 3 months: DRPs, adherence (assessed by 8-item Morisky Adherence Questionnaire), patient's knowledge (assessed by Coronary Artery Disease Questionnaire), 36-Short Form Health Survey (SF-36), heart rate, systolic and diastolic blood pressure, low-density lipoprotein (LDL), total cholesterol (TC) and fasting blood glucose (FBG). After 3 months, there was a significant difference between the intervention and control groups in the per cent change of DRPs (median: -100 vs 5.882, P = 0.0001), patient's adherence score (median: 39.13 vs -14.58, P = 0.0001), knowledge score (median: 30.28 vs -5.196, P = 0.0001), SF-36 scores, heart rate (mean: -10.04 vs 6.791, P = 0.0001), diastolic blood pressure (mean: -17.87 vs 10.45, P = 0.0001), systolic blood pressure (mean: -16.22 vs 4.751, P = 0.0001), LDL (median: -25.73 vs -0.2538, P = 0.0071), TC (median: -14.62 vs 4.123, P = 0.0005) and FBG (median: -11.42 vs 5.422, P = 0.0098). Clinical pharmacists can play an important role as part of a cardiac rehabilitation team through patient education and interventions to minimize DRPs.
