Comparative Study of the Foot Arch Index Among Pregnant and Non-pregnant Women in a South Eastern Nigeria Community: A Cross-Sectional Analysis

Objective: Physical and hormonal changes during pregnancy result in biomechanical alterations which result in re-adjustments in the musculoskeletal system. Influence of these changes on the foot during gestation has been understudied. The aim of this study was to compare the arch indexes of pregnant and non-pregnant women and then determine the relationship between arch index and each of gestational age and body mass index (BMI) of pregnant women. Materials and Methods: In this study, 328 (215 pregnant women in different trimesters and 113 nulliparous women) participants were selected from Enugu in South-Eastern Nigeria. Their arch indexes were obtained from their foot prints. Data was summarized using frequency counts, mean, standard deviation and percentages. Inferential statistics of independent t test and Pearson correlation test were used to determine the differences and relationships among variables with alpha level set at P < 0.05. Results: Results showed that a greater percentage of the pregnant women (57.2% on the right foot and 59.1% on the left foot) had low arches, indicating pes planus as compared to their age-matched nulliparous counterparts (19.5% on the right and 23.3% on the left). Statistical analysis further showed significant differences between the arch indexes of women in both groups. No significant relationship was found among gestational trimesters, BMI and arch index of pregnant women. Conclusion: Pregnant women have lower arch indexes, indicating pes planus, than nulliparous women. Gestational trimesters and BMI had no associations with the arch index during pregnancy

Relationship between physical activity level and flexibility profile of Nigerian postpartum women

Flexibility is an essential component of musculoskeletal health and is usually associated with physical activity levels. Pregnancy and its aftermath may influence physical activity participation and musculoskeletal flexibility in women, which warrants this study. Thus, this study aimed to assess the physical activity level and musculoskeletal flexibility profile of Nigerian Postpartum women. In this cross-sectional study, 462 postpartum women were conveniently sampled from Healthcare Facilities in Anambra State, Nigeria. Physical Activity was assessed using Global Physical Activity Questionnaire while flexibility profile was assessed using modified sit-and-reach (for the lower back and limb components), total body rotation (for trunk component) and shoulder rotation tests (for upper limb components). Relevant inferential statistics were used to compare variables between the two groups of women. The results showed that 42.0% of the women were fairly flexible and 51.1% of them had high Physical Activity level. Majority (77.6%) of their daily physical activities were from work. Statistically, there was no significant relationship between their physical activity levels and flexibility profile of the participants (p = 0.066). The postpartum physical activity level of the respondents is not a determinant of their musculoskeletal flexibility. Recommendation of structured physical exercises, particularly flexibility trainings to postpartum women in Nigeria is necessary for optimum maintenance of their general postpartum and musculoskeletal health
