Abstract
BACKGROUND: Body mass index (BMI) is calculated by dividing a person's height in meters by their weight in kilograms and is always expressed in kg/m2. BMI is a reliable risk indicator for various diseases that can develop due to a higher percentage of body fat. There is a possibility of developing certain medical conditions including heart disease, high blood pressure, type 2 diabetes, gallstones, breathing problems and some malignancies that increase with BMI. OBJECTIVE: This study seeks to identify the trends in the Body Mass Index (BMI) of women visiting Better Life Primary Health Care Centre in Ondo City, Ondo State, Nigeria for various healthcare services. METHODOLOGY: Seventy (70) women who participated in this study were randomly selected using systematic random sampling. Their necessary information was obtained using a prepared record sheet to collect their data. Results were analysed using SPSS version 21. RESULTS: The results show mean age of the respondents is 30.50 + 6.52921 21 (30%) were between 31 – 35 years, 21 (30%) were traders, 36 (51%) had tertiary education, 39 (55.7%) were between 151 – 160 cm in height. 32 (45.7%) were between 60 – 80 kg in weight and 30 (42.9%) had normal weight, respectively. CONCLUSION: Body Mass Index (BMI) calculation is an essential tool that can help in identifying one of the significant public health issues that leads to obesity; a predisposing factor to various medical conditions like hypertension, musculoskeletal issues, heart diseases, cancers, and lots more. It is therefore important to incorporate BMI calculation into routine checks to prevent or reduce health burdens that may arise from obesity.

Introduction
One of the most important medical and public health problems of our time is obesity.[1] Excess body fat not only places a significant burden on healthcare systems, but also represents a significant risk factor for several common diseases, including diabetes and cardiovascular disease. The American Medical Association recently recognized obesity as a disease, further emphasizing its importance as a public health issue, and raising awareness of its importance as a public health issue.[2] Various methods can be used to measure obesity. Body mass index or BMI is calculated by dividing a person's height in meters by their weight in kilograms and is always expressed in kg/m2
Body Mass Index (BMI) = mass (kg)
height (m2)
Applications of BMI frequently depend on the differentiation of "healthy" and "unhealthy" BMI distribution parts.[3] BMI is a ratio that has been in use since the middle of the 19th century. It is used to detect adults and teenagers who are overweight abnormally for their height.[4] Several research have been done linking BMI to various disease mechanisms and due to its use as a stratification measure in many clinical treatment guidelines, it is crucial for a physician to grasp BMI.[4] Due to its widespread acceptance as a classification of body fatness, body mass index has proven to be a valuable tool. People who have a high proportion of lean body mass, for instance, may be considered "overweight" even when they have a low body fat percentage. Other anthropometric measurements may be more clinically relevant in these circumstances. Another caution is that many studies have demonstrated that morbidity and mortality are influenced by the physical distribution of adipose tissue.[4]
BMI is a great measure that is simple to use and beneficial for many patient populations. However, investigations on the relationship between BMI and the risk of death occasionally employ non-standard BMI categories that differ among studies. In a meta-analysis of 8 big studies with 5.8 million individuals that utilized non-standard BMI categories and were published between 1999 and 2014, hazard ratios tended to be low across the spectrum of overweight and normal weight. People with a high-normal weight (BMI of roughly 23.0 – 24.9) and those with a mild overweight had comparable risks (BMI of approximately 25.0 – 27.4).[5] Recent decades have seen an increase in obesity rates, which has raised serious concerns among policymakers. A significant burden on healthcare systems is caused by excess body fat, which is frequently assessed by the body mass index (BMI), which is a key risk factor for several prevalent ailments like diabetes and cardiovascular disease.[6]
The most often used indicator of relative weight is body mass index (BMI). It can be employed at the population level when it would be impracticable or too expensive to quantify (extra) body fat reliably and consistently, as well as at the individual level to assess body weight in a clinical situation.[6] The application of statistical techniques in BMI-related studies may support:
- Examine the BMI-related factors and determine the connections between BMI and correlated (perhaps causative) components.
- Look into the role that BMI may have in the morbidity and mortality caused by many associated disorders.
- Examine the BMI categorization and deal with uncertainties.
- By evaluating and generating predictions, help the policy-making process.

Methods
Study area
The research was conducted in Better Life Primary Healthcare Centre, Ondo City, Ondo State Nigeria. The Better Life Primary Health Centre is located at Okelisa/Okedoko, Ondo West Local Government, Ondo State. It was established on 1st January 2007 and operates on 24 hours basis. The Better Life Primary Health Centre is licensed hospital by the Nigeria Ministry of Health and registered as Primary Health Care Centre. Ondo City is the second largest town in Ondo State, Nigeria.
Study population
The study population consists of seventy (70) women visiting Better Life Primary Health Care Centre, Ondo City, Ondo State Nigeria for various healthcare services.
Study design and sampling
This study was a cross – sectional descriptive study. A systematic random sampling was used in selecting seventy (70) participants for this study. Their socio-demographics information and Body Mass Index (BMI) readings of the participants were taken.
Data collection methods
The data was collected from seventy (70) participants using appropriate tools. The data comprises of two sections namely socio-demographic characteristics and Body Mass Index (BMI) readings of the respondents.
Data analysis
The results were analysed using Statistical Package for Service Solutions (SPSS) Version 21.
Ethical consideration
Approval to conduct this research was obtained from the coordinator of the primary health centre. Informed consents were obtained from the participants and their confidentiality was ensured.

Discussion
Socio-Demographics information of the participants
The results show mean age of the respondents is 30.50 + 6.52921, (30%) were between 31 – 35 years, 18 (25.7%) were between 26 – 30 years and 17 (24.3%) were between 21 – 25 years old. 21 (30%) were traders, 13 (18.6%) were teachers and 7 (10%) were students and tailors respectively. 36 (51%) had tertiary education and 28 (40%) had secondary school education.
Body Mass Index (BMI) of the participants
From the results, 39 (55.7%) were between 151 – 160 cm and 19 (27.1%) were between 161 – 170 cm in height. 32 (45.7%) were between 60 – 80 kg and 29 (41.4%) were between 40 – 60 kg in weight respectively. 30 (42.9%) had normal weight, 24 (34.3%) were overweight, 10 (14.3%) were in Obese Class I categories, 3 (4.3%) were underweight, 2 (2.9%) were in Obese Class II categories and 1 (1.4%) were in Obese Class III categories.
Conclusion
From this study, it is revealed that larger percentage of these women were still in their various reproductive stages. Also, some of these women are overweight and obese. BMI is very crucial in identifying the body weight status of individual. Several studies have linked being obese to various medical conditions that are dangerous to our health and wellbeing. It is therefore recommended that awareness creation on BMI essentials and incorporating BMI calculations into the healthcare settings so patients can know their body weight status whenever they come for any healthcare services should be encouraged.
