Forensic application of foot dimensions in ethnic differentiation among Ghanaians.

BACKGROUND AND AIM: Foot dimensions are known parameters for height estimation and personal identification in most developed countries but there appears to be dearth of information about their utilization in developing countries. Therefore, the present study sought to provide ethnic-specific baseline data on foot dimensions and bring to light the differences that exist between some ethnic groups in Ghana. METHODS: One hundred and ninety-three undergraduate students consisting of Ashantis, Fantes and Ewes were recruited.  Plantar surfaces were scanned and foot dimensions were taken. RESULTS: The left 1st, right 2nd and 3rd toe-pternion lengths and the right breadth at ball were the only dimensions that exhibited differences between the Ashanti and Fante ethnic groups. However, differences were recorded between the Ashanti and Ewe feet for all the measurements taken. Also, with the exception of the right 5th toe-pternion length, all the dimensions exhibited differences. CONCLUSIONS: Inter-ethnic differences exist for the dimensions of the foot between the ethnic groups that were involved in the present study. The present study has provided ethnic specific baseline data on foot dimensions for identification purposes.

Determinants of modern contraceptive use among married women of reproductive age: a cross-sectional study in rural Zambia.

OBJECTIVE: Zambia is among the world's top 10 countries with higher fertility rate (5.5 births/woman); unmet family planning need for births spacing (14%) and limiting births (7%). Women in rural Zambia (24%) are reported to have unmet need for family planning than those in urban areas (17%). This study was conducted to ascertain factors associated with modern contraceptive use among rural Zambian women. DESIGN: Cross-sectional study. SETTING: Rural Zambia. PARTICIPANTS: Secondary data of 4903 married or cohabiting rural women (15-49 years) after filtering out the pregnant, urban based and unmarried women from 2013 to 2014 Zambian Demographic and Health Survey (ZDHS) were analysed using SPSS V.22. Multiple logistic regression, Pearson's χ2 and descriptive statistics were performed to examine factors associated with modern contraceptive use. RESULTS: Factors that were positively associated with contraceptive use were respondent's education (secondary adjusted ORs (AOR = 1.61, p≤0.002); higher (AOR = 2.39, p≤0.050)), wealth index (middle class, (AOR = 1.35, p≤0.005); rich (AOR = 2.04, p≤0.001) and richest (AOR = 1.95, p≤0.034)), high parity (1-2 (AOR = 5.31, p≤0.001); 3-4 (AOR = 7.06, p≤0.001); 5+ (AOR = 8.02, p≤0.001)), men older than women by <10 years (AOR = 1.50, p≤0.026) and women sensitised about family planning at health facility (AOR = 1.73, p≤0.001). However, old age (40-49 years (AOR = 0.49, p≤0.001)), other religions (Protestants, African traditionalists and Muslims) (AOR = 0.77, p≤0.007), ever had pregnancy miscarried, aborted or stillbirth (AOR = 0.78, p≤0.026) and women without knowledge of number of children husband desires (AOR = 0.71, p≤0.001) were negatively associated with contraceptive use. CONCLUSION: Modern contraceptive use in rural Zambia among currently married women of reproductive age group is relatively low (43%). We recommend that appropriate interventions are instituted to increase contraceptive access and use especially among uneducated older rural Zambian women.

Association of ABO Blood Group and Body Mass Index: A Cross-Sectional Study from a Ghanaian Population.

ABO blood group and body mass index (BMI) have individually been appraised as risk factors for certain diseases. From statistical perspective, it may be important to examine the relationship between the ABO blood antigen and BMI. This cross-sectional study involved 412 participants aged 18 to 46 at the Kwame Nkrumah University of Science and Technology (KNUST), Kumasi. Weight and height of participants were measured for BMI calculation; blood group determination was done using antisera. Blood group O was the most prevalent (51.2%), while Rhesus-positive individuals constituted 90.3%. 6.3% of the participants were obese, while 18.7% were overweight. There was significant (p=0.006) higher prevalence of obesity in females (10.3%) than in males (3.4%). The study did not observe any significant difference by association of ABO blood group with gender (p=0.973), BMI (p=0.307), or Rhesus status (p=0.723). Regarding gender (p=0.400) and BMI (p=0.197), no statistically significant difference was observed between Rhesus blood groups. The prevalence of overweight, obesity, blood type O, and rhesus positive observed among students in this study is largely similar to what has been reported in published studies in Ghana and from other countries. Overweight and obesity were not associated with ABO blood groups or Rhesus in this study.
