Structured physical exercise programs during pregnancy appear to be safe for the neonate, mainly favoring a lower birth weight within normal range. However, more studies are needed to establish recommendations.

ACS had no positive impact on schoolchildren's health. Distance to school is an indicator of active commuting. However, it seems that not enough physical activity is done to prevent obesity and cardiometabolic risk factors in rural areas.

The identification of research priorities in line with current health needs and nursing competencies is a priority. Nevertheless, barriers and facilitators perceived by nurses to performing nursing research have scarcely been investigated. The main aim of this study was to explore the situation in nursing research in Spain, as perceived by Spanish experts. A Delphi study technique in two phases was applied using an online survey tool. A panel of 20 nursing experts in nursing, teaching and management positions participated. The strengths highlighted were the possibility of reaching the PhD level, the possibility of receiving continuous training in research methodology, and access to scientific knowledge through the Internet. The weaknesses identified were the lack of Spanish nursing journals in which to publish the research results, the lack of funding in nursing care research, and the lack of connection between the healthcare institutions and the university. According to the experts, elements that could enhance leadership in research are the creation of nursing research units in hospitals, the economic recognition of nurses with PhDs, and considering research work as part of their daily tasks in clinical settings. The idea of being subordinated to physicians still remains in nurses’ ways of thinking.

The aims of this study were to examine sex differences in college students while they performed cardiopulmonary resuscitation (CPR) on a manikin for 20 min in (a) objective and subjective effort indicators and (b) to analyse the influence of potential confounders (age, BMI and cardiorespiratory fitness) on these sex differences. Sixty-three participants were recruited. Participants performed 20 min of CPR on a manikin. During the CPR trial, percentages of maximal heart rate levels were higher in women than in men (P<0.05) and perceived exertion increased significantly in both sexes over time (P=0.05); furthermore, at the last two time points analysed, women scored higher than men (P<0.05). However, these sex differences disappeared when controlling for age, BMI and cardiorespiratory fitness. In conclusion, indicators of exertion during CPR are higher in women than in men, but these sex differences are because of BMI and differences in physical fitness conditions.
