Long-Term Dietary and Physical Activity Interventions in the School Setting and Their Effects on BMI in Children Aged 6-12 Years: Meta-Analysis of Randomized Controlled Clinical Trials.

Preventive actions and potential obesity interventions for children are mainly researched throughout the school period, either as part of the school curricula or after regular school hours, via interventions mostly lasting less than 12 months. We aimed to perform a meta-analysis on randomized controlled clinical trials to evaluate the evidence of the efficacy of long-term school-based interventions in the management of childhood obesity in terms of BMI from a dietary and physical activity-based approach. Eleven randomized controlled clinical trials were examined using the random effects model, and the results showed that there were no significant effects associated with physical activity + nutrition intervention in school children aged 6-12 years, with a pooled standardized mean difference (SMD) (95% CI) of -0.00 (-0.05, 0.04). No effects were observed after subgroup analysis based on the intervention length. The findings from our study indicate that long-term school-based interventions on physical activity and dietary habits received by children aged 6-12 years seem to have no effect on BMI. However, the promotion of such interventions should not be discouraged, as they promote additional positive health outcomes for other domains of children's health.

Impact of a Postoperative Intervention Educational Program on the Quality of Life of Patients with Hip Fracture: A Randomized, Open-Label Controlled Trial.

The objective of this study was to determine the impact of a postoperative educational intervention program on the health-related quality of life (HRQoL) of patients with hip fracture using a controlled clinical trial in a randomized, multicenter study. In total, 102 patients (45.5%) from trauma units at the two University Hospitals of the province of Cáceres received the educational program, whereas 122 (54.5%) did not. Patients were consecutively included in either an intervention or a control group. Patients from the intervention group received an educational program during admission and the postoperative period. Patients from the control group did not receive any educational program. These patients were managed according to routine protocols. The patients were predominantly female (76.3%), aged 84.6 years (SD 6.1). All dimensions in both groups at 12 months showed a significant decrease with respect to baseline, except for bodily pain in both groups (p = 0.447; p = 0.827) and social functioning in the intervention group (p = 0.268). Patients receiving the educational program showed higher levels in the dimensions of the Mental Component Summary (MCS-12) (p = 0.043), vitality (p = 0.010), and social functioning (p < 0.001), as well as in the dimensions of the SF-12 health survey questionnaire of HRQoL 12 months after surgery. In conclusion, our study of the intervention group showed that there were significant improvements in MCS-12, vitality, and social function dimensions compared to the control group.

Nursing Genetic Research: New Insights Linking Breast Cancer Genetics and Bone Density.

Nursing research is expected to provide options for the primary prevention of disease and health promotion, regardless of pathology or disease. Nurses have the skills to develop and lead research that addresses the relationship between genetic factors and health. Increasing genetic knowledge and research capacity through interdisciplinary cooperation as well as the development of research resources, will accelerate the rate at which nurses contribute to the knowledge about genetics and health. There are currently different fields in which knowledge can be expanded by research developed from the nursing field. Here, we present an emerging field of research in which it is hypothesized that genetics may affect bone metabolism. Better insight of genetic factors that are contributing to metabolic bone diseases would allow for focused nursing care and preventive interventions.

Quality of life after hip fracture: a 12-month prospective study.

BACKGROUND: Hip fracture is an important and frequent health problem worldwide. To date, there are still limited studies focused on the analysis of health-related quality of life (HRQOL) after a hip fracture in the Spanish population, especially with long-term follow-up. OBJECTIVE: To determine the HRQOL at 12 months after hip fracture and to identify potential factors associated with HRQOL. DESIGN: Prospective observational study. SETTING: Traumatology units of two university hospitals in province Cáceres (Spain). PARTICIPANTS: A total of 224 patients were admitted to the unit and required immediate surgery due to a hip fracture. METHODS: HRQOL was measured with the EuroQol-5D questionnaire (EQ-5D) and the SF-12 Health Survey. RESULTS: Scores from the visual analog scale EQ-5D decreased significantly (p < 0.001) from 72.8 at baseline to 48.3 after 1 month, to 48.2 after 6 months and to 46.1 after 12 months. The EQ-5D index score showed a similar significant reduction (p < 0.001) from 0.6 to 0.1, 0.3 and 0.3, respectively. Values of the physical component summary (PCS-12) significantly decreased (p < 0.001) from 38.6 at baseline to 31.0, 33.1 and 33.5. The mental component summary (MCS-12) decreased from 46.5 to 44.8 after 6 months (p = 0.022) and 44.3 after 12 months (p = 0.005). Factors potentially associated with HRQOL at 12 months after hip fracture were depression status after 12 months (B = 0-1.876; 95% CI [-2.409 to -1.343]; p < 0.001), functional ambulation classification after 12 months (B = -12.133; 95% CI [-17.970 to -6.297]; p < 0.001), EQ-5D VAS at baseline (B = 0.223; 95% CI [0.115-0.330]; p < 0.001), and age (B = -0.323; 95% CI [-0.594 to -0.053; p = 0.015). CONCLUSIONS: Patients experience a significant impairment in HRQOL H after a hip fracture, especially in self-care, pain/discomfort, usual activities, mobility and anxiety/depression. The decline in the HRQOL is effective the first month and lasts at least 12 months after the surgical intervention.

Quality of life in elderly people after a hip fracture: a prospective study.

BACKGROUND: Hip fracture is an important social and medical problem due to its increasing prevalence, the consequences for health and the economic impact on the health care system, but there is no doubt that it also has repercussions on health-related quality of life (HRQoL). Hence the importance of understanding and determining the impact of the condition on everyday life from the perspective of the patient's physical, emotional and social well-being. PURPOSE: To determine the impact of hip fracture on HRQoL of people over the age of 65 1 month after surgery, related factors and the effects on functional ability and mood. METHODS: Prospective observational study conducted in the traumatology units of two university hospitals in the province of Cáceres with consecutive sampling of all patients over the age of 65 admitted for hip fracture surgery during the study period. Sociodemographic and clinical data were recorded at the time of admission and prospectively at the follow-up visit 1 month later. Clinical, social, quality of life (EQ-5D-), basic functional and instrumental capacity (Barthel Index (BI) and Lawton & Brody Scale), and geriatric depression (Yesavage) variables were collected. RESULTS: The study included 224 patients with a median age of 84.6 years (SD ± 6.1), 76.3% were female. Charlson's comorbidity was 5.3 (SD ± 1.2). The EQ-5D index decreased from 0.62 (SD ± 0.35) to 0.16 at 1 month follow up (SD ± 0.20) p <  0.001. The mean Visual Analog Scale (VAS) score of EQ-5D decreased from 72.8 (SD ±15.8) to 48.3 (SD ± 17.2) p <  0.001. All dimensions of EQ-5D showed a significant reduction from the time of pre-fracture status to 1 month after surgery. Independent factors associated with HRQoL 1 month after surgery were pre-fracture status Barthel Index score, Lawton and Brody scale, presence of depression, and type of surgery. CONCLUSIONS: After a hip fracture, patients experience considerable deterioration in their HRQoL, especially in self-care, daily activities, and mobility. There is also a significant decline in functional capacity for both the basic and instrumental activities of daily living. One month after surgery, HRQoL is a long way from pre-fracture levels.

Olive Oil Consumption and Bone Microarchitecture in Spanish Women.

Olive oil has been demonstrated to enhance various cardiometabolic risk factors. However, to our knowledge, the association between olive oil intake and cortical and trabecular bone microarchitecture has never been evaluated in Spanish women. We aimed to examine the association between olive oil intake and cortical and trabecular bone microarchitecture. We analyzed 523 women aged 50 (9) year, range (23⁻81) year. Participants underwent dual-energy X-ray absorptiometry and peripheral quantitative computed tomography scans. Dietary intake of calcium, vitamin D, energy and olive oil (g/day) were assessed by a self-administered food frequency questionnaire (FFQ). After adjustment for potential confounding factors (calcium (mg/day), vitamin D (µg/day) energy (Kcal/day), age, body mass index (BMI) (kg/m²), menopausal status, and osteoporotic diagnosis (normal, osteopenia, or osteoporosis)), there were significant increases in volumetric bone mineral density (vBMD) (mg/cm³) (p < 0.01) in the group with a higher intake of olive oil. Total, trabecular and cortical bone density were positively correlated with olive oil intake. The dietary intake of olive oil was significantly associated with vBMD in multiple regression analysis; total density: olive oil intake (g/day) standardized ß = 0.185 (p < 0.001), trabecular density: olive oil intake (g/day) standardized ß = 0.186 (p < 0.001) and cortical density olive oil intake (g/day) standardized ß = 0.114 (p = 0.008). We conclude that the dietary intake of olive oil is positively associated with a better vBMD in Spanish women.

Dietary Intake of Cadmium, Lead and Mercury and Its Association with Bone Health in Healthy Premenopausal Women.

The bone is one of the relevant target organs of heavy metals, and heavy metal toxicity is associated with several degenerative processes, such osteoporosis and bone mineral alterations, that could lead to fractures. We aimed to study a presumed relationship between bone density, evaluated by quantitative bone ultrasound (QUS), dual-energy X-ray absorptiometry (DXA) and peripheral quantitative computed tomography (pQCT) and the dietary intake of cadmium, lead and mercury in healthy premenopausal women. A total of 158 healthy, non-smoking, premenopausal women were incorporated into the study. A validated food frequency questionnaire (FFQ) was administered to assess intake during the preceding seven days. The median predicted dietary cadmium intake among the 158 women studied was 25.29 µg/day (18.62-35.00) and 2.74 µg/kg body weight/week (b.w./w) (1.92-3.83). Dietary lead intake was 43.85 µg/day (35.09-51.45) and 4.82 µg/kg b.w./w (3.67-6.13). The observed dietary mercury intake was 9.55 µg/day (7.18-13.57) and 1.02 µg/kg b.w./w (0.71-1.48). Comparisons, in terms of heavy metal intake, showed no significant results after further adjusting for energy intake. No statistically significant correlations between heavy metal intake and the QUS, DXA and pQCT parameters were observed. Levels of dietary exposure of cadmium, lead and mercury were mostly within the recommendations. We did not find associations between the QUS, DXA and pQCT parameters and the dietary intake of the studied heavy metals in healthy premenopausal women.

Evaluation of the Dietary Intake of Cadmium, Lead and Mercury and Its Relationship with Bone Health among Postmenopausal Women in Spain.

BACKGROUND: Heavy metals, such as lead, cadmium, and mercury, are absorbed through contaminated food sources and water. Few studies have investigated the extent to which dietary heavy metals are associated with low bone mineral density. AIMS: We aimed to characterize the dietary intake of the heavy metals lead, cadmium and mercury among healthy, non-smoking postmenopausal women in Spain. Furthermore, we sought to establish a putative relationship between bone health and the intake of these heavy metals in this population. STUDY DESIGN: The daily intake of the heavy metals considered for the different food groups was calculated by accounting for food content and consumption in 281 postmenopausal women. Bone measurements were performed using a Quantitative Bone Ultrasound (QUS), a Dual-Energy X-ray Absorptiometry (DXA) and a Peripheral Quantitative Computed Tomography (pQCT). RESULTS: The average estimated dietary cadmium exposure among the 281 women studied was 29.87 µg/day (20.41-41.04) and 3.03 µg/kg body weight (b.w.; 2.17-4.40). Dietary lead exposure was 46.24 µg/day (38.11-54.77) and 4.87 µg/kg b.w. (4.00-6.14). The estimated dietary mercury exposure was 11.64 µg/day and 1.19 µg/kg b.w. (0.82-1.76). Participants were classified according to their heavy metal intake (above or below the respective medians). After further adjustment for potential confounding factors, no significant differences were found in all the measured parameters (p > 0.05). CONCLUSIONS: We did not find associations between bone health and the dietary intake of three heavy metals in postmenopausal women. Dietary intake of the measured heavy metals were within the recommended values.

Antiproliferative Properties of Oleuropein in Human Osteosarcoma Cells.

In this study, we evaluated the antiproliferative activity on two human osteosarcoma cell lines (MG-63 and Saos2) of oleuropein, an olive oil compound traditionally found in the Mediterranean diet. Oleuropein exhibited obvious cytotoxic effects on human osteosarcoma cells in a concentration- and time-dependent manner. Statistical analysis of IC50 by the Probit regression method suggested that oleuropein had similar toxic effects on both cell lines tested (IC50 range from 247.4-475.0 µM for MG63 cells and from 798.7-359.9 µM for Saos2 cells).

Effect of beer drinking on ultrasound bone mass in women.

OBJECTIVE: To study the effect of beer consumption on bone mass in a group of healthy women, by using phalangeal bone ultrasound to evaluate the amplitude-dependent speed of sound. METHODS: This was a cross-sectional study of 1697 healthy women (mean age 48.4 y, body mass index (BMI) 19.0-32.0 kg/m(2)), recruited in a clinical convenience sample and screened for the existence of disease and/or medication that would affect calcium metabolism. Of this total, 710 were premenopausal, 176 were perimenopausal, and 811 were postmenopausal. The women recruited completed a questionnaire that contained detailed sections on current cigarette, alcohol, caffeine, and nutrient consumption. In terms of current alcohol intake, the subjects were classified as moderate drinkers, light drinkers, and nondrinkers. Drinkers were also analyzed according to the kind of alcohol consumed: wine or beer. RESULTS: Quantitative bone ultrasound values were greater in the beer drinkers compared with the no beer and/or wine drinkers. Taking the amplitude-dependent speed of sound as a dependent variable, and age, BMI, gonadal status, intake of beer and wine, and number of cigarettes per day as independent variables, we found age (beta = -1.52), BMI (beta = -3.86), gonadal status (beta = -27.47), and beer intake (beta = 1.06) to be significant. CONCLUSION: The greater bone density found in women beer drinkers might be a result of the phytoestrogen content of this alcoholic drink; this requires further investigation.
