Validation of the attitudes towards people living with HIV/AIDS scale in nursing students.

BACKGROUND: One of the environments where people living with HIV/AIDS should feel safer is in the health care setting; however, scientific evidence has identified discriminatory behaviour on the part of health care professionals towards these people. The reduction or abolition of discriminatory practices requires, first of all, to know the attitudes of nursing students towards AIDS with tools appropriate to the socio-cultural context of the disease. The objectives of this study are to update the AIDS Attitudes Scale for Nursing Students (EASE) by adapting it to the sociocultural landscape and to analyse the reliability and structural validity of the new scale. METHODS: The results of the questionnaires answered by 213 undergraduate nursing students from the Faculty of Health Sciences of Ceuta (University of Granada) were analysed. Reliability (test-retest, n = 33) and validity (n = 180) tests were carried out. RESULTS: An exploratory and confirmatory factor analysis indicated that a four-factor model was the most parsimonious solution. Items were examined for their underlying relationships and labelled: professional practice, social integration, partner and family, and benevolent stigma. The new scale yielded a McDonald's Omega coefficient (ω) of 0.893. Convergent validity was established for average variance extracted per factor greater than 0.5 and divergent validity when the variance retained by each factor is greater than the variance shared between them (average variance extracted per factor > ϕ2). CONCLUSIONS: The new scale is a psychometrically sound instrument for assessing attitudes towards people living with HIV/AIDS in nursing students.

Levels and predictors of postpartum depression and anxiety during the first year of the COVID-19 pandemic in a confined cross-border city.

Pregnancy and/or the puerperium involve social, physiological and psychological changes that make women more vulnerable to mental disorders such as anxiety and depression, even more so if these develop in stressful contexts such as the pandemic. The aim of this study is to identify factors associated with the risk of postpartum anxiety and depression during the COVID-19 pandemic. A cross-sectional study was conducted among postpartum women (n = 69) who gave birth between March 2020 and March 2021 in Melilla, a Spanish cross-border city with Morocco whose borders were closed, making it a confined city. The scales used were the State-Trait Anxiety Inventory and the Edinburgh Postnatal Depression Scale. Results reported an elevated risk of depression (85.5%) and anxiety (63.8%), with severe anxiety reaching 40.6% of cases. Predictors of postpartum depression comprised a personal history of mood disorders (ß = 8.421; CI95% = 4.863/11.978) and having been diagnosed with COVID-19 during pregnancy or postpartum (ß = 4.488; CI95% = 1.331/7.646). As regards anxiety, it is predicted on the basis of mood antecedents (ß = 14.175; CI95% = 7.870/20.479), the fact of having been diagnosed with COVID-19 during pregnancy or postpartum (ß = 8.781; CI95% = 2.970/14.592) and the fact of being a multipara (ß = 5.513; CI95% = 0.706/10.321). In conclusion, special attention should be paid to women with a history of mood disorders and a positive diagnosis of COVID-19 during pregnancy or postpartum, even more so in the case of multiparous women, because of its impact on mental health during the postpartum period.

Psychometric validation of the Prenatal Distress Questionnaire (PDQ) in pregnant women in Spain.

The Prenatal Distress Questionnaire (PDQ) was developed among English-speaking women in the United States to assess specific worries and concerns during pregnancy. Our aim was to analyze the factor structure of the PDQ, using confirmatory factor analysis, and assess its convergent validity in Spanish women. A sample of 233 pregnant women with ages ranging from 19 to 42 years in the south of Spain (Europe) (January 2015 - March 2016) completed the translated PDQ, the Perceived Stress Scale (PSS) and the Symptom Checklist-90-revised (SCL-90-R). Confirmatory factor analysis revealed a three-factor structure supporting the original PDQ factor structure (χ2 (31) = 55.43, p = 0.004; CFI = 0.96; RMSEA = 0.058; WRMR = 0.702). The Spanish PDQ significantly correlated with the PSS and SCL-90-R (r's 0.18-0.49, p's < 0.05), providing evidence of convergent validity. These results illustrate that the stress dimensions investigated by the PDQ adequately represent pregnant women's distress across a different cultural context and corroborate the psychometric properties of this instrument previously demonstrated in English-speaking women. The Spanish version of the PDQ can be used by clinical practitioners to evaluate specific worries and concerns women experience during pregnancy.

The Pitt Bacteremia Score, Charlson Comorbidity Index and Chronic Disease Score are useful tools for the prediction of mortality in patients with Candida bloodstream infection.

Candida bloodstream infection (CBI) is associated with high mortality. The aim of this study was to compare the utility of the combined use of the Pitt Bacteremia Score (PBS) and Charlson Comorbidity Index (CCI) or Chronic Disease Score (CDS) to predict mortality among patients with CBI. Thereby, all consecutive patients with CBI at our institution between 2010 and 2014 were included. The PBS was used to evaluate CBI severity and the CCI and CDS were used to assess comorbidities of patients with CBI. Logistic regression analysis was used to estimate odds ratios for 30-day mortality in models including the PBS and CCI or CDS. A total of 189 CBI episodes were identified. Logistic regression models including the PBS and either CCI or CDS showed that the combined use of a comorbidity score and a severity score significantly predicted 30-day mortality. The performance of the different models was similar. Aggregated scores of comorbidity (CCI and CDS) and disease severity (PBS) are useful for the prediction of 30-day mortality risk in patients with CBI. Their use may facilitate the analysis of risk factors for poorer outcome and the development of an index for CBI mortality.

Sexual orientation and its impact on sexual behaviour of young people aged 15-29: a cross-sectional study.

AIMS: The aim of this study was to determine whether there was a direct relation between sexual orientation and sexual practices involving penetration; to analyse whether condom use in the first sexual relation was conditioned by sexual orientation; to verify whether consistent condom use in sexual relations was determined by sexual orientation. BACKGROUND: Recent research suggests that sexual orientation (i.e. heterosexuality, homosexuality or bisexuality) is a determining factor in high-risk sexual behaviour. DESIGN: A cross-sectional study with purposive sampling. METHODS: Data were collected between March 2013-April 2014 from 900 participants (524 males and 376 females). All participants were 15-29 years of age. Their mean age was 20·93 years. The participants were given a socio-demographic survey as well as a psychometric test on high-risk sexual behaviour, which had been used in previous studies. RESULTS: There were no statistically significant differences in relation to sexual orientation and sexual practices involving penetration either in the general model for both sexes or in the models for men and women. It was also found that sexual orientation did not significantly affect condom use in the first sexual relation. Furthermore, consistent condom use had a protector effect in the general model for homosexuals and bisexuals. In the model for men, this was also true for homosexuals and in the model for women, this was the case for bisexuals. CONCLUSION: Condom use in the first sexual relation was similar in all sexual orientations. However, the sexual orientation of the subject was found to be a determining factor in consistent condom use.

Psychological assessment among immigrant and Spanish women during the postpartum period in Spain.

OBJECTIVE: to describe whether there were differences in sociodemographic, obstetric, perinatal and psychological variables between immigrant women and native-born women in Spain during the first 24 h after delivery. BACKGROUND: The immediate postpartum period is a critical time when physical and psychological disorders are likely to occur. Immigrant women have, in general, poor perinatal and psychological results during this time. METHODS: One hundred and three women at the Virgen de las Nieves University Hospital (Granada, Spain) were divided into two groups: 50 Spanish and 53 immigrants. The instruments used were the Life Orientation Test, the Stress Vulnerability Inventory, the Perceived Stress Scale and the Symptom Checklist-90-Revised (SCL-90-R). Sociodemographic and obstetric data were obtained from the healthcare providers reports. RESULTS: During the postpartum period, the immigrant women had higher mean scores on the following subscales: interpersonal sensitivity (F(1,102) = 4.06; p < 0.05); depression (F(1,102) = 7.24; p < 0.01); phobic anxiety (F(1,102) = 4.83; p < 0.05), paranoid ideation (F(1,102) = 7.20; p < 0.01); and psychoticism (F(1,102) = 4.04; p < 0.05). When considering age, education, profession, job situation, immigrant status of the partner and duration of time in Spain as covariates, differences between groups were significant on obsessive-compulsiveness (F(1,102) = 5.37; p < 0.05) and depression (F(1,102) = 6.89; p < 0.05). CONCLUSIONS: Immigrant women are in need of more psychological and emotional support from their families, midwives and the rest of healthcare providers than are native Spaniards immediately after delivery.

Evaluation of pain in healthy newborns and in newborns with developmental problems (Down syndrome).

Newborns are often subjected to invasive and painful medical procedures. This happens even more frequently when they require hospitalization. The aim of this paper was to evaluate pain in healthy newborns and in newborns with Down syndrome (DS). We performed a prospective cohort study in the neonatal service of the San Cecilio University Hospital in Granada (Spain) from January 2008 to September 2013. The universe of our study comprised a study group of 20 newborns with DS and a control group of 20 newborns without DS. All of the infants were hospitalized, and thus had to undergo painful medical procedures. The variables studied were basal recovery time (as reflected in crying and the normalization of biological constants), number of punctures, oxygen saturation, heartbeat, blood pressure, response to skin-to-skin contact, and gestational age. The evaluation was performed during blood extraction, vein canalization, and heel puncture. The significant differences in the basal recovery time between the two groups of newborns indicated that those with DS were slower to express pain, and when they did, their response was not as clearly defined as that of babies without DS. The oxygen saturation in babies with DS after the puncture was found to be significantly lower than that of the control group (p < .001). The results of this study revealed that babies with DS were not as quick to perceive pain after a puncture. However, when pain was finally perceived, it persisted for a longer time. This situation should be taken into account in the design of pharmacologic and nonpharmacologic therapies.

Gender-based differences in the high-risk sexual behaviours of young people aged 15-29 in Melilla (Spain): a cross-sectional study.

BACKGROUND: Research confirms the existence of gender-based differences regarding the high-risk sexual behaviour (non-use of condoms and casual partners) of young men and women. The objectives were to provide evidence for this association; to analyse the reasons why both sexes have sexual relations with casual partners and to ascertain the motives for condom use or non-use during casual sex. METHODS: A cross-sectional study was performed on a sample of 900 participants, 524 males and 376 females. All participants were 15-29 (20.93 ± 4.071) years of age and came from four different centres (a university, two secondary schools, and a military base) in Melilla (Spain). The participants were given a socio-demographic survey as well as a psychometric text on high-risk sexual behaviour. RESULTS: The results found gender-based significant differences for sexual relations with penetration (p = 0.001), number of sexual partners (p = 0.001), and sexual relations with casual partners (p = 0.001). In all of these variables, male participants had higher percentages than female participants. Reasons for having casual sexual relations were also different for men and women, differences were found for the items, opportunity (p = 0.001), interest in knowing the other person (p = 0.015), physical excitement (p = 0.056) and drug consumption (p = 0.059). Regarding the reasons for consistent condom use with casual partners, there were differences for the item, my demand of a condom (p = 0.002). For the non-use of condoms with casual partners, differences were found for the items, I do not like to use condoms (p = 0.001) and condoms lessen sensitivity and reduce pleasure (p = 0.009). CONCLUSIONS: Men and women were found to have different high-risk sexual behaviours and practices. Of the motives for having sexual relations with casual partners, male participants considered opportunity and interest in knowing the other person to be more important than the female participants. Regarding condom use, the female participants' demand to use a condom was a significant gender-based difference. In contrast to the young women, the male participants mostly justified not using a condom because it lessened sensitivity and reduced pleasure.

Impact of Work-Life Balance on the Quality of Life of Spanish Nurses during the Sixth Wave of the COVID-19 Pandemic: A Cross-Sectional Study.

This study addresses the health-related quality of life (HRQoL) of Spanish nurses during the sixth wave of the COVID-19 pandemic, assessed through the EQ-5D and EQ-VAS indices. METHODS: This cross-sectional 334 study used online surveys, recruiting 305 Spanish nurses. RESULTS: Nurses generally perceived a good HRQoL. "Negative work-family interaction" is adversely associated with the EQ-VAS (ß = -0.337, 95% CI [-1.733, -0.723]) and EQ-5D (ß = -0.399, 95% CI [-0.021, -0.01]) indices, while "positive work-family interaction" shows a positive relationship with the EQ-VAS (ß = 0.218, 95% CI [0.381, 1.759]). The presence of a "paid supportive caregiver" is positively associated with the EQ-VAS (ß = 0.18, 95% CI [1.47, 12.3]) and EQ-5D (ß = 0.149, 95% CI [0.004, 0.117]) indices, but a higher "number of children" is negatively linked with the EQ-5D index (ß = -0.146, 95% CI [-0.061, -0.002]). In addition, living with a partner (EQ-VAS ß = 0.16, 95% CI [1.094, 14.67] and EQ-5D index ß = 0.174, 95% CI [0.018, 0.163]) and working a "rotating shift" (EQ-5D index ß = 0.158, 95% CI [0.005, 0.098]) are positively associated. CONCLUSIONS: These findings highlight the need to comprehensively address nurses' well-being, considering both their working conditions and their home environment, especially in crisis contexts such as the current pandemic.

Epidemiological cutoff values for fluconazole, itraconazole, posaconazole, and voriconazole for six Candida species as determined by the colorimetric Sensititre YeastOne method.

In the absence of clinical breakpoints (CBP), epidemiological cutoff values (ECVs) are useful to separate wild-type (WT) isolates (without mechanisms of resistance) from non-WT isolates (those that can harbor some resistance mechanisms), which is the goal of susceptibility tests. Sensititre YeastOne (SYO) is a widely used method to determine susceptibility of Candida spp. to antifungal agents. The CLSI CBP have been established, but not for the SYO method. The ECVs for four azoles, obtained using MIC distributions determined by the SYO method, were calculated via five methods (three statistical methods and based on the MIC50 and modal MIC). Respectively, the median ECVs (in mg/liter) of the five methods for fluconazole, itraconazole, posaconazole, and voriconazole (in parentheses: the percentage of isolates inhibited by MICs equal to or less than the ECVs; the number of isolates tested) were as follows: 2 (94.4%; 944), 0.5 (96.7%; 942), 0.25 (97.6%; 673), and 0.06 (96.7%; 849) for Candida albicans; 4 (86.1%; 642), 0.5 (99.4%; 642), 0.12 (93.9%; 392), and 0.06 (86.9%; 559) for C. parapsilosis; 8 (94.9%; 175), 1 (93.7%; 175), 2 (93.6%; 125), and 0.25 (90.4%; 167) for C. tropicalis; 128 (98.6%; 212), 4 (95.8%; 212), 4 (96.0%; 173), and 2 (98.5; 205) for C. glabrata; 256 (100%; 53), 1 (98.1%; 53), 1 (100%; 33), and 1 (97.9%; 48) for C. krusei; 4 (89.2%; 93), 0.5 (100%; 93), 0.25 (100%; 33), and 0.06 (87.7%; 73) for C. orthopsilosis. All methods included ≥94% of isolates and yielded similar ECVs (within 1 dilution). These ECVs would be suitable for monitoring emergence of isolates with reduced susceptibility by using the SYO method.

[Legislative knowledge and preparation of health personnel for the care process of death]. / Conocimiento de la ley y preparación del personal sanitario sobre el proceso asistencial de la muerte.

The aims of this study were to ascertain the perception that health professionals (doctors, nurses and nursing assistants) have about their preparation for the care of terminally ill patients and to determine their knowledge about palliative care legislation. This cross sectional study was performed at a hospital in Granada (Spain); we administered an ad hoc questionnaire. The results indicated that although most of the staff had worked with terminally ill patients, only half believed that they have been trained to care for them. A significant proportion stated that they did not know about the current palliative care legislation. Most professionals would question the withdrawal of therapies for the maintenance of life; most of them are also unaware of the mechanism for reporting on the completion of a Living Will, as well as a Plan for Palliative Care in Andalusia (Spain).

Sexually Transmitted Infections in 2000-2018 in a Specialised Centre: Comparison between Pre-Crisis, Crisis, and Post-Crisis Period.

(1) Background: Sexually Transmitted Infections (STIs) are a major public health problem due to their consequences in sexual and reproductive health. There is a close link between the crisis and the increase in communicable diseases. The objective of this study was to analyse the evolution of Sexually Transmitted Infections during the period 2000-2018 in the population attending the Centre for Sexually Transmitted Diseases and Sexual Orientation in Granada (Spain), specifically comparing the pre-crisis, crisis, and post-crisis periods. (2) Methods: A retrospective, observational, and analytical study was conducted by reviewing medical records. The sample analysed comprised 1666 cases. (3) Results: During the pre-crisis period (2000-2007), the percentage of diagnoses was 41.6% (n = 126) compared to 58.4% (n = 177) of negative results; during the crisis, the percentages were 63.5% (n = 183) and 36.5% (n = 105), respectively; and during the post-crisis period, the percentages were 42.9% (n = 157) and 57.1% (n = 209), respectively. The variables that were significantly associated with STI diagnosis were the time periods analysed, sexual orientation, occupation, and age at first intercourse. The evolution of the number of positive diagnoses during the entire study period showed a trend of progressive increase in Sexually Transmitted Infections from 2000 to 2018. (4) Conclusions: The period of economic crisis presented a higher risk of infection, although this is a finding with certain limitations due to the lack of homogeneity between the periods analysed.

Epidemiological Profile of Patients with Vulvovaginal Candidiasis from a Sexually Transmitted Infection Clinic in Southern Spain.

Epidemiological data on women suffering from vulvovaginal candidiasis and its recurrence are outdated and vague. The aim of this study was to identify the prevalence of women diagnosed with vulvovaginal candidiasis, as well as the epidemiological profile and associated risk factors in the province of Granada (Spain). Data from the Centre for Sexually Transmitted Infections of the Granada province between 2000 and 2018 (N = 438) were used in this study. Associations between sociodemographic and sexual behaviour variables with vulvovaginal candidiasis were analysed using the Chi-square test and bivariate logistic regression. The prevalence of candidiasis was 14.6%. The sociodemographic profile corresponded to a woman aged 25.14 ± 4.8 years on average, who is of Spanish nationality (60.9%), a student (55.7%), in non-active employment (59.7%), with a higher education (56.7%), single (93.5%), and under 30 years of age (79.7%). Variables associated with this diagnosis were the absence of oro-genital contact (OR = 1.99; 95% CI = 0.25-0.74), having a regular partner (OR = 1.99; 95% CI = 1.05-3.75), and age of sexual debut, with the probability increasing by 12% (95% CI = 1.00-1.24) with each year. In this context, vulvovaginal candidiasis infection is common, and its epidemiological profile is contradictory, so our results do not suggest a relevant role of sexual risk behaviours in the diagnosis. Further research is needed to improve the estimates and factors associated with this infection.

[Functional evolution in elderly individuals with hip fracture surgery]. / Evaluación funcional en ancianos intervenidos de fractura de cadera.

This prospective study was performed in patients aged 65 years or older who underwent hip fracture surgery. The objective was to determine the functional evolution in a group of patients three months after hospital discharge, to identify the variables related to this functional recovery and to describe the associated mortality and institutionalization process. We analyzed demographic variables such as age, sex, and living situation. Other aspects considered included: comorbidity, cognitive impairment, walking ability, dependency level according to Barthel's Index, institutionalization, and mortality. The information was collected on admission and three months after discharge. Considering the entire sample, 89.6% was female and the average age was 83.56 years; 40% of patients regained their prior independence and a 16.7% mortality rate was registered, together with a slight progression toward institutionalization. The functional capacity and cognitive impairment of patients before the fracture are determinants of functional recovery and subsequent recovery of independence.

Epidemiology and antifungal susceptibility of bloodstream fungal isolates in pediatric patients: a Spanish multicenter prospective survey.

Data on fungemia epidemiology and antifungal susceptibility of isolates from children are scarce, leading frequently to pediatric empirical treatment based on available adult data. The present study was designed to update the epidemiological, mycological, and in vitro susceptibility data on fungal isolates from children with fungemia in Spain. All fungemia episodes were identified prospectively by blood culture over 13 months at 30 hospitals. Tests of susceptibility to amphotericin B, flucytosine, fluconazole, itraconazole, posaconazole, voriconazole, anidulafungin, caspofungin, and micafungin were performed at participant institutions by a microdilution colorimetric method. New species-specific clinical breakpoints for fluconazole, voriconazole, and echinocandins were also applied. A total of 203 episodes of fungemia in 200 children were identified. A higher proportion of fungal isolates was from general wards than intensive care units (ICU). Candida parapsilosis (46.8%), Candida albicans (36.5%), Candida tropicalis (5.9%), Candida glabrata (3.9%), and Candida guilliermondii (2.5%) were the leading species. C. parapsilosis was the predominant species except in neonates. C. albicans was the most frequent in neonatal ICU settings (51.9%). Intravascular catheter (79.3%), surgery (35%), prematurity (30%), and neutropenia (11%) were the most frequent predisposing factors. Most Candida isolates (95.1%) were susceptible to all antifungals. When the new species-specific clinical breakpoints were applied, all C. parapsilosis isolates were susceptible to echinocandins except one, which was micafungin resistant. This is the largest published series of fungemia episodes in the pediatric setting. C. parapsilosis is the most prevalent species in Spain, followed by C. albicans and C. tropicalis. Resistance to azole and echinocandin agents is extremely rare among Candida species. The fluconazole resistance rate in Spain has decreased in the last 10 years.

[Education about healthy sexual behaviors among high school students]. / Educar en conductas sexuales saludables: una innovación docente en promoción de la salud.

BACKGROUND: The need to educate adolescents about healthy sexual behavior motivated the development of an education program on sexuality. AIM: To describe the knowledge of students about sexuality and the implementation of a sexual education project. MATERIAL AND METHODS: Sixty students aged 14 years (34 females), attending the third year of secondary education participated in dynamic workshops about healthy sexual behaviors. RESULTS: The most common reactions of students when facing situations related to sexual behavior were shame, anxiety, fear and lack of knowledge. Group dynamics improved the practical knowledge of students about sexual behavior, allowing them to make informed decisions. CONCLUSIONS: These innovative educational techniques should be expanded to other students.

Posters as a Tool to Improve Hand Hygiene among Health Science Students: Case-Control Study.

(1) Background: Numerous educational interventions have been conducted to improve hand hygiene (HH) compliance and effectiveness among nursing students, with mixed results. The aim is to evaluate the effectiveness of posters as a teaching tool and factors associated with HH quality. (2) Methods: A pre-post experimental intervention study was conducted with a total of 293 nursing students randomly assigned to two groups (experimental and control) who, before and after HH, took cell culture samples from their non-dominant hands. Only the experimental group was exposed to the poster. (3) Results: In the experimental group, significant differences were observed among students older than 22 years (p = 0.017; V = 0.188), with a higher percentage of failures (15.7% vs. 3.6%). Poster displaying was associated with passing, other variables being equal, although without statistical significance (ORa = 2.07; 95% CI = 0.81-5.26). Pre-practice hand contamination was weakly associated with lower HH quality (ORa = 0.99, 95% CI = 0.99-0.99). (4) Conclusions: The use of posters as a teaching method shows indications of efficacy. Prior hand contamination slightly affects the quality of HH. Further evaluation of teaching methods is needed to ensure good technical performance of HH to prevent the spread of infectious diseases during the COVID-19 pandemic.

Validation of the Women's Views of Birth Labor Satisfaction Questionnaire (WOMBLSQ4) in the Spanish Population.

The satisfaction of women with the birth experience has implications for the health and wellness of the women themselves and also of their newborn baby. The objectives of this study were to determine the factor structure of the Women's Views of Birth Labor Satisfaction Questionnaire (WOMBLSQ4) questionnaire on satisfaction with the attention received during birth delivery in Spanish women and to compare the level of satisfaction of pregnant women during the birth process with that in other studies that validated this instrument. A cross-sectional study using a self-completed questionnaire of 385 Spanish-speaking puerperal women who gave birth in the Public University Hospitals of Granada (Spain) was conducted. An exploratory factor analysis of the WOMBLSQ4 questionnaire was performed to identify the best fit model. Those items that showed commonalities higher than 0.50 were kept in the questionnaire. Using the principal components method, nine factors with eigenvalues greater than one were extracted after merging pain-related factors into a single item. These factors explain 90% of the global variance, indicating the high internal consistency of the full scale. In the model resulting from the WOMBLSQ4 questionnaire, its nine dimensions measure the levels of satisfaction of puerperal women with childbirth care. Average scores somewhat higher than those of the original questionnaire and close to those achieved in the study carried out in Madrid (Spain) were obtained. In clinical practice, this scale may be relevant for measuring the levels of satisfaction during childbirth of Spanish-speaking women.

Influence of Physical Activity on Blood Pressure in Children With Overweight/Obesity: A Randomized Clinical Trial.

BACKGROUND: The prevalence of childhood hypertension (HT) is growing exponentially, influenced by environmental factors such as foods with high salt content, sedentary lifestyles, and poor-quality food. The incidence of HT is about 10.4% in well-nourished children, but when associated with obesity or overweight, this can rise to 38% and 68%, respectively. To assess the influence of physical activity on the blood pressure (BP) of children who are overweight or obese. METHODS: This randomized clinical trial was carried out in Granada (Spain), from October 2015 to June 2016. The sample consisted of 98 children, all of whom were overweight or obese. The intervention group (IG) (n = 49) practised physical activity and received nutritional advice, while the control group (n = 49) only received theoretical-practical sessions on nutrition. Body composition was measured, a nutritional assessment was made and BP was determined (in percentiles, to avoid the misclassification of children who are located at the extremes of normal growth). RESULTS: Before the physical activity intervention, 85.7% of the children in the IG (with overweight/obesity) were in the 95th or higher percentile for BP, a situation representative of high BP (HT). However, by the end of the study period, this value had decreased significantly (P = 0.001), to 16.13%. CONCLUSIONS: Childhood obesity is a risk factor for HT. Physical activity, together with nutritional advice, effectively reduces BP in children who are overweight or obese. The use of percentiles, according to age, weight, and height, is an effective means of measuring BP.
