Abstract: Study Objective: To determine the prevalence, characteristics and effects on the activities of daily living of menstruation disturbances among adolescent girls. Design: Descriptive, cross-sectional study. Setting: A public school in the city of Petrolina, Brazil. Participants: 218 female adolescents of ages between 12 and 17 years. Main Outcome Measure: We used a structured questionnaire addressing the socio-demographic and menstrual characteristics of the adolescents. The intensity of menstrual pain and its effect on the activities of daily living were measured using an 11-point numeric rating scale. Results: The mean age of adolescent girls was 13.7 ± 1.5 years. The menstrual cycles of 67% were regular, while 33% were irregular. Dysmenorrhea had a prevalence of 73%, and school absenteeism was observed among 31% of the adolescents. In addition, 66% of the participants considered that dysmenorrhea affected their activities of daily living. Associations were found between the intensity of pain and the variables: school absenteeism; affected activities of daily living; need to use medications; and between affected activities of daily living and school absenteeism (P < .05). Conclusions: Among the menstrual disturbances observed dysmenorrhea stood out due to its high prevalence among adolescents with a negative effect on adolescents’ activities of daily living. Early diagnosis and knowledge about menstrual disturbances are essential because in addition to reiterating the importance of implementing health education actions, they also help to choose appropriate treatments, thus minimizing the negative effects of these disturbances on the lives of adolescents.

The aim of this study was to evaluate the acute effect of the use of stable and unstable surfaces on electromyography (EMG) activity and coactivation of the scapular and upper-limb muscles during the push-up plus (with full protraction of the scapula). Muscle activation of anterior deltoid (AD), posterior deltoid (PD), pectoralis major, biceps brachii (BB), triceps brachii (TB), upper trapezius (UT), middle trapezius (MT), lower trapezius (LT), and serratus anterior (SA) levels and coactivation index were determined by surface EMG in 20 young men during push-up plus performed on a stable and unstable condition (2 unstable devices applied to hands and feet). The paired t test and Cohen d were used for statistical analysis. The results showed that during the execution of the push-up plus on the unstable surface an increased EMG activity of the scapular stabilizing muscles (SA, MT, and LT) was observed, while AD and PD muscles showed a decrease. During exercise execution on the unstable surface there was a higher index of coactivation of the scapular muscles (SA-MT and UT-LT pairs). No significant differences were observed in TB-BB and AD-PD pairs. These results suggest that the push-up-plus exercise associated with unstable surfaces produced greater EMG activity levels and coactivation index of the scapular stabilizing muscle. On the other hand, the use of an unstable surface does not promote the same effect for the shoulder muscles. [ABSTRACT FROM AUTHOR]

Objective: To describe the prevalence of headache and its interference in the activities of daily living (ADL) in female adolescent students. Methods: This descriptive cross-sectional study enrolled 228 female adolescents from a public school in the city of Petrolina, Pernambuco, Northeast Brazil, aged ten to 19 years. A self-administered structured questionnaire about socio-demographic characteristics, occurrence of headache and its characteristics was employed. Headaches were classified according to the International Headache Society criteria. The chi-square test was used to verify possible associations, being significant p<0.05. Results: After the exclusion of 24 questionnaires that did not met the inclusion criteria, 204 questionnaires were analyzed. The mean age of the adolescents was 14.0±1.4 years. The prevalence of headache was 87.7%. Of the adolescents with headache, 0.5% presented migraine without pure menstrual aura; 6.7%, migraine without aura related to menstruation; 1.6%, non-menstrual migraine without aura; 11.7%, tension-type headache and 79.3%, other headaches. Significant associations were found between pain intensity and the following variables: absenteeism (p=0.001); interference in ADL (p<0.001); medication use (p<0.001); age (p=0.045) and seek for medical care (p<0.022). Conclusions: The prevalence of headache in female adolescents observed in this study was high, with a negative impact in ADL and school attendance. [ABSTRACT FROM AUTHOR]
