Abstract:

Considering the various limitations of using chronological age, biological age estimation is becoming increasingly recognized as one of the novel public health and clinical strategies for preventing and controlling the rising global prevalence of noncommunicable diseases (NCDs) and for achieving healthy ageing. The objectives of this study are to estimate the biological age and compare it to the chronological age of Nigerian adults. Also, to score the magnitude of some of the lifestyle determinants of biological age among the study population. This cross-sectional study uses simple random sampling technique to select 82 Nigerian adults for the study, while standardized instruments were used to collect data. The P value for the study was set at 0.05 level of significance. The result of the study noticed poor mean Mediterranean Diet Adherence (MDAQ) score of 7.0 ± 2.28 and mean International Physical Activity (IPAQ) score of 1.3 ± 0.51. There was also suboptimal mean Pittsburgh Sleep Quality Index (PSQI) score of 5.9 ± 3.01, mean Perceive Stress Scale-4 (PSS-4) score of 6.3 ± 2.79, and mean Social Connectedness Scale (SCS) score of 15.2 ± 4.13. Furthermore, the estimated biological age of the respondents (45.9 years, ±10.31), was higher than their chronological age (43.2 years, ±8.92). The study concluded that the magnitudes of the lifestyle determinants of ageing are high enough to result in accelerated biological ageing among the study population. Such development, if not mitigated, may result in a significant increase in the prevalence of NCDs and premature deaths in the near future.
