Knowledge, awareness, and attitude of premarital screening with special focus on sickle cell disease: a study from Odisha

Knowledge, attitudes, and practices of sickle cell hemoglobinopathies: A case-control study from the sickle cell belt of Odisha, India

Despite the high prevalence of sickle cell haemoglobin (HbS) in Odisha, awareness and understanding of sickle cell trait (SCT) and sickle cell disease (SCD) remain low in affected communities. This cross-sectional study assesses the knowledge, attitude, and practice (KAP) regarding sickle cell hemoglobinopathies among 182 sickle cell carriers and 200 age-sex-community matched controls. The overall knowledge of sickle cell hemoglobinopathies was very low among both case and control groups (score 2.8/10). Although most respondents had heard about SCD (85.71% vs. 82%), few were aware of SCT (34.07% vs. 27%). Notably, none of the participants knew their haemoglobin genotype or carrier status. Only a very small proportion were aware of symptoms, causes, and preventive measures. The overall attitude score was marginally higher in the control group (4.75/11) than in the case group (4.55/11), with an average score of 42.25%. While most recognized the need for regular treatment and screening of children (82.4% carriers, 90.5% controls), many were undecided about the necessity of premarital screening. The overall practice score was very low in both groups (0.4/5), but the mean practice score was significantly higher in cases than controls (11.01% vs. 7.55%). Most participants did not undergo regular health check-ups or engage in preventive measures (97.25%). Traditional health practices were commonly relied upon for treatment. Participants reported a lack of awareness about SCT and fear of discrimination, social isolation, and marriage refusal as major barriers to screening participation.

Beliefs negatively mediate adolescents' and adults' knowledge about sickle cell disease prevention and relationship choices; a one-center exploratory study in Central Region, Ghana

BACKGROUND

Sickle cell disease (SCD) is a common monogenic inheritable condition in sub-Saharan Africa. 30% of Ghanaians are estimated to be carriers creating a condition for stable SCD penetrance. Being inheritable, SCD is scientifically preventable through intentional spousal selection. This study therefore explored young adults' knowledge, beliefs and prevention strategies regarding SCD.

METHODS

This exploratory study employed a mixed-methods approach (semi-structured questionnaires and focus group discussion [FGD]) to explore the SCD knowledge and beliefs of participants (15-49 years). The data collection was intentionally sequential; initial administration of 386 questionnaires and then followed by the FGD (16 participants). FGD was thematically analysed whereas quantitative data was explored using structural equation modeling (SEM); p < 0.05 was considered statistically significant under two-tailed assumptions.

RESULTS

Whereas 98.7% reported having heard about SCD, < 50% got the information through formal education. Overall, 49.7% knew their respective SCD status; the proportion increased with age (48.8% in < 30 years vs 64.4% in ≥ 30 years old), or higher degree status (48.8% in undergraduates vs 67.4% in postgraduates). Moreover, whereas nine-in-ten correctly identified that SCD is hereditable, three-in-ten believed that having a SCD child was a matter of fate. Our FGD revealed that whereas curses, and spiritual attack were misconceived as potential causes of SCD, stigmatization associated with SCD was a major concern. The SEM demonstrated that one's knowledge about SCD prevention is significantly positively associated with relationship choices (b = 0.757, p < 0.05). Also, a participant's knowledge about SCD preventive strategies was significantly associated with the individual's beliefs about SCD (b = 0.335; p < 0.05). However, a participant's SCD beliefs negatively mediated SCD preventive strategies-relationship choices association.

CONCLUSIONS

SCD beliefs likely transform linear quantitative associations into a complex non-linear interaction; public health campaigns ought to unearth and address SCD beliefs to maximize achieving the intended targets.

Comparative assessment of quality of life among adolescents with sickle cell disease and sickle cell trait: evidence from Odisha, India

The present study aims to assess the quality of life (QOL) of adolescents with sickle cell disease (SCD) and sickle cell trait (SCT) in hard-to-reach regions in Koraput district of Odisha state. 387 adolescents with sickle cell genes (HbSS = 52, HbAS = 135, HbA = 200) were selected through their medical records from southern parts of Odisha. A validated and pretested QOL scale was modified to assess the QOL. The questionnaires were modified by aiming to describe the proportion of adolescents who feel restricted in different domains, measuring the extent within each domain, and finding an aggregate score of QOL. Furthermore, to explore the expenditure on health, 552 households were selected randomly, of which 72 families had HbS individuals. This study found a significantly lower health-related QOL in adolescents with SCD. However, most psychosocial sub-domains, for instance, worry about the illness, frequency of angry days, feeling jealousness toward other normal adolescents, and negative feelings of sadness on some days, are similarly affected in adolescents with SCT and SCD. The overall QOL of SCD individuals is more affected (percentage of affected mean score = 60.93%), followed by SCT individuals (35.63%). Healthy adolescents' QOL is relatively unaffected (13% were affected). The yearly frequency of blood transfusion received (1.7 ± 0.4) and hospitalization (2.1 ± 0.9) was significantly higher in adolescents with SCD. The healthcare expenditure was significantly higher (3.6% to 81.3% of the family income) in families with HbS than in families without HbS (0.8% to 19.2%) (p < 0.05). The overall QOL was affected in both SCD and SCT adolescents. The focus should be given equally to both SCD and SCT individuals, in spite of only SCD individuals.

Endline assessment of knowledge about sickle cell disease among the tribal community of Chhotaudepur district of Gujarat

Sickle cell disease (SCD) is a significant public health concern in India, with one of the highest disability burdens worldwide. For the success of the disease prevention and control program that aims to reduce prevalence through health promotion and screening, the public's prior knowledge of the disease is important. Hence, this study was conducted to assess baseline knowledge of the disease and effects of health education and community mobilization program in the SCD endemic tribal community of Gujarat. This quasi-experimental study was conducted in three phases at Chhotaudepur district of Gujarat, India. Knowledge of the community was assessed through the administration of pretested quantitative questionnaire in 1646 and 1631 individuals respectively during formative and evaluation phases. Differences between the proportions of two phases were statistically assessed by chi-square tests. Despite 75.3% of respondents having heard of SCD before, only 20% could perceive the correct cause. It was improved by 42% post-intervention. During the evaluation, 83% respondents recognized the most common symptom of extreme pain, whereas 86.8% identified the correct diagnostic method. Seventy-seven percent respondents reported modern medicine as a treatment for SCD at endline. Knowledge and awareness about SCD were found inadequate in the community. However, health education intervention strategies effectively improved knowledge related to the disease and its causes, diagnosis, and treatment. Hence, urgent action is required to incorporate community mobilization and awareness generation strategies to mitigate the disease burden.

Assessing knowledge of sickle cell disease and health beliefs on premarital genetic screening among healthcare trainees at a tertiary institution: A cross-sectional study

Background

The uptake of sickle cell trait (SCT) test is challenged by several factors. A community of healthcare professionals educating the public to undergo screening is critical in reducing the disease burden. We investigated knowledge and attitude towards premarital SCT screening among healthcare trainee students who are the next generation of healthcare practitioners.

Methods

A cross-sectional design was employed, and quantitative data were collected from 451 female students pursuing healthcare programs at a tertiary institution in Ghana. Descriptive, bivariate, and multivariate logistic regression analysis was performed.

Results

More than half of the participants were 20-24 years (54.55%) and had good knowledge (71.18%) about sickle cell disease (SCD). Age and school or social media as sources of information were significantly associated with good knowledge about SCD. Students between the age 20-24 (adjusted odds ratio [AOR] = 2.54, confidence interval [CI] = 1.30-4.97) and knowledge (AOR = 2.19, CI = 1.41-3.39) were 3 times and 2 times more likely to have a positive perception about SCD severity. Students who have SCT (AOR = 5.16, CI = 2.46-10.82), whose source of information was family member/friends (AOR = 2.83, CI = 1.44-5.59) and social media (AOR = 4.59, CI = 2.09-10.12) were 5 times, 2 times and 5 times likely to have a positive perception about the susceptibility of SCD. Students whose source of information is school (AOR = 2.06, CI = 1.11-3.81) and who have good knowledge of SCD (AOR = 2.25, CI = 1.44-3.52) were 2 times more likely to have a positive perception about the benefits of testing. Students with SCT (AOR = 2.64, CI = 1.36-5.13) and source of information was social media (AOR = 3.01, CI = 1.36-6.64) were about 3 times more likely to have a positive perception about the barriers to testing.

Conclusion

Our data shows that high level of SCD knowledge influences positive perceptions about the severity of SCD, the benefits and relatively low barriers to SCT or SCD testing and genetic counseling. Dissemination of SCT, SCD and premarital genetic counseling education should be intensified especially in schools.
