This study aimed to investigate and analyze the level of awareness and adoption of distributed ledger technologies (DLTs) within the Nigerian construction industry. The focus was on addressing the current state of DLT utilization, identifying challenges and opportunities and proposing strategies to enhance the integration of DLTs into the construction processes and practices of Nigerian professionals and organizations.

The research was underpinned by a robust theoretical and conceptual framework, drawing from established theories of technology adoption. A comprehensive literature review guided the identification of various DLT types. This informed the development of a well-structured questionnaire, which was then distributed to Nigerian construction professionals. The collected data underwent analysis using percentages, frequencies, mean scores, the Kruskal–Wallis H-test and the Shapiro–Wilk test.

A significant finding of this study reveals a generally low awareness and implementation of DLT among construction professionals in Nigeria. These findings emphasize the urgent need for comprehensive strategies to bridge the gap between awareness and adoption of DLT within the Nigerian construction industry.

Industry associations, regulatory bodies and educational institutions can collaborate to develop specialized programs aimed at familiarizing professionals with the benefits and applications of DLTs. Additionally, technology providers and policymakers can leverage these findings to design user-friendly interfaces and guidelines for seamless DLT integration into construction processes.

This study contributes to the existing body of knowledge by providing a comprehensive assessment of the awareness and adoption of DLTs specifically within the Nigerian construction industry. While the global recognition of DLT’s potential in construction is acknowledged, this research delves into a regional context, shedding light on the specific opportunities within Nigeria. Furthermore, the study’s identification of a gap between awareness and implementation highlights a critical area for future exploration and development in the field of construction technology adoption.

This study was designed to assess the risk factors associated with hypertension (HTN) and diabetes among artisans in Ogun State, Nigeria. Evidences suggest increasing prevalence, incidences and morbidity of diabetes and HTN in Nigeria. However, the purpose of this study is to plan and prioritize effective intervention programs, there is need to provide data on the prevalence and risk factors for HTN and diabetes among local groups.

In total 300 apparently healthy artisans who have never been diagnosed of diabetes or HTN were randomly selected from five communities. A structured questionnaire was used in obtaining information on the personal characteristics of the respondents. An adapted dietary habit and lifestyle questionnaire were used to assess the dietary habits and lifestyle of the respondents. The WHO global activity questionnaire was adapted and used to gather information on the physical activity level of the respondents. Random blood glucose, blood pressure and anthropometric measurements were assessed using standard instruments. Chi-square (χ²), correlations and multinomial logistic regression analysis were performed to identify significant determinants of diabetes and HTN.

Mean age was 34.8 ± 9.9 and prevalence of diabetes and pre-diabetes were 1 and 4.7 per cent, respectively, while HTN and pre-HTN were 48.0 and 30.3 per cent, respectively. About half (55.7 per cent) of the respondents skip at least a meal daily and 31 per cent snack daily. Most (61.4 per cent) consume alcohol and 65.7 per cent engage in high physical activity. Abdominal obesity was significantly higher among women (p = 0.004). Using the chi-square analysis, age, abdominal obesity and educational status were factors found to be significantly associated with diabetes (p = 0.002; p = 0.007; p = 0.004) while age, gender, abdominal obesity and alcohol consumption had significant association with HTN. Although not statistically significant, respondents were 0.8, 1.0 and 1.1 times more likely to be diabetic with increasing body mass index, waist circumference (WC) and age (odd ratio (OR) = 0.78; confidence intervals (CI): 0.51-1.18; OR = 1.04; CI: 0.89-1.21; OR = 1.06; CI: 0.96-1.18, respectively). Abdominal obesity was significantly associated with HTN (OR = 1.08; CI: 1.03-1.13; p = 0.001). Also, older respondents were 1.1 times more likely of becoming hypertensive (OR = 1.07; CI: 1.02-1.11; p = 0.003). Increased risk of diabetes and HTN was found among respondents with increasing age and WC.

This study was cross-sectional in design; it cannot be used to establish a cause-effect relationship between diabetes, HTN and the observed variables (anthropometric characteristics, dietary habits and lifestyle risk factors). Because of the few numbers (1 per cent) of respondents identified to be diabetic several important risk factors could not be included in the model.

An understanding of the risk factors associated with diabetes and HTN among sub-groups in the population will help to plan effective interventions targeted at specific groups.

The findings of this study show the associated risk factors for diabetes and HTN among artisans in Ogun State.
