Adhesion to the Mediterranean diet in diabetic patients with poor control. / Adherencia a la dieta mediterránea en pacientes diabéticos con mal control.

OBJECTIVE: To analyse the relationship between the level of adherence to the Mediterranean diet and the control of cardiovascular risk factors. METHOD: A descriptive, observational study was conducted on patients diagnosed with Diabetes Mellitus type 2, with poor blood glucose control and a Body Mass Index greater than 25kg/m2. The relationship between the adherence to the Mediterranean diet and cardiovascular risk factors was evaluated before and after education about the Mediterranean diet. The patients were given a questionnaire on the level of adherence to the Mediterranean diet (the Mediterranean diet score), at the beginning of the study and at 6 month after having education about the Mediterranean diet in the Primary Care medical and nursing clinics. An analysis was carried out on the variables including, gender, age, weight, height, and Body Mass Index, as well as the analytical parameters of blood glucose, glycosylated haemoglobin, total, HDL, LDL cholesterol, and triglycerides. The relationship between the primary variable, 'adherence to the Mediterranean diet', and the rest of the variables was calculated before and after the educational intervention. RESULTS: The initial 'adherence to the Mediterranean diet score' in the questionnaire was relatively low (6.22). Excess weight, as well as to have an elevated Body Mass Index are associated with a lower adherence to the Mediterranean diet, as well as low adherence to treatment (P<.00 and P<.02, respectively). The values of HDL cholesterol values increased with greater adherence (P<.04). Elevated LDL and total cholesterol are associated with a lower adherence to the Mediterranean diet (P<.01 and P<.05, respectively), similar to that of elevated triglycerides (P<.00). Elevated baseline blood glucose levels are also associated with low adherence to the Mediterranean diet (P<.04), as well as the increase in glycosylated haemoglobin (P<.06). Thus the cardiovascular risk increases with low adherence (P<.08). After the educational intervention, a moderate increase was observed in the adherence to the Mediterranean diet (a score of 6.84) as well as a notable improvement in the control of the cardiovascular risk factors. CONCLUSIONS: Adherence to the Mediterranean diet is associated with improved control of cardiovascular risk factors.

Effect of a motivational physical activity program on lipid parameters in patients with obesity and overweight. / Efecto de un programa de actividad física motivada en los parámetros lipídicos de pacientes con obesidad o sobrepeso.

OBJECTIVE: To assess the effect of a motivated physical activity program on the lipid parameters most related to excess weight (triglycerides [TG], and high density lipoprotein cholesterol [HDL]) in a weight-loss intervention in obese and overweight patients. METHODS: A randomised and controlled, 2-arm, clinical trial and a 12-months follow-up was conducted. The patients included in the study were randomised into 2 intervention groups: Motivational intervention of obesity with a previously trained nurse (G1), motivational group, with digital platform support and motivated physical activity program (iwopi [G2]). The anthropometric variables measured were height, weight, Body Mass Index (BMI), as well as the analytical variables, total cholesterol, TG and HDL-C. RESULTS: A total of 123 patients participated in the study, of which 61 were randomised to G1, and 62 to G2. Both groups significantly decreased weight at the end of the study, with the decrease in G1 being 4.898kg, and 6.292kg in G2. In both groups there was also a significantly decrease (P<.05) in total cholesterol and TG, and increase in HDL cholesterol, with these changes being more intense in the G2 group, as well as being the group that lost more weight. CONCLUSIONS: Weight reduction is accompanied by favourable changes in lipid parameters related to overweight and obesity, being more intense the greater the weight loss.

Effect on the lipid parameters of an intervention to reduce weight in overweight and obese patients. / Efecto sobre los parámetros lipídicos de una intervención para reducir peso en pacientes con sobrepeso y obesidad.

OBJECTIVE: To assess the effect on lipid parameters most associated with excess weight (triglycerides [TG], cholesterol, and high density lipoprotein [HDL-C]) of an intervention to reduce weight in overweight and obese patients. METHODS: A randomised, controlled, double blind clinical trial, with three groups, and a follow-up of 12 months. Patients included in the study were randomised into three intervention groups: Obesity motivational intervention group with previously trained nurse (G1), lower intensity consultation, non-motivational group, with digital platform support (G2), and a third group that received a recommendation to lose weight and usual follow-up (G3). The anthropometric variables measured were height, weight, and abdominal/waist circumference, and laboratory results, total cholesterol, TG and HDL cholesterol). RESULTS: The study include 176 patients, of whom 60 were randomised to G1, 61 to G2, and 59 to G3. All groups significantly decreased body weight at the end of the study, with a decrease in G1 (-5.6kg), followed by G2 (-4.3kg), and G3 (-1.7kg), with an overall mean loss of -3.9kg. There was a also significant decrease (P<.05) in total cholesterol and TG, and an increased HDL-C. These changes were more marked in the G1 group (the group that lost more weight). The clinical relevance indicators that were significant were: in the case of TG: G1/G3: relative risk: 1.42 (95% CI: 1.11-1.80); relative risk reduction: 41.7% (11.4-80.2); absolute risk reduction: 25% (9.2-40.8) and NNT: 5 (3-11). In the case of G1/G2 HDL-C: relative risk: 1.32 (1.07-1.63); relative risk reduction: 32.2% (7.4-62.6); absolute risk reduction: 21.1% (6.4-35.8) and NNT: 5 (3-16). CONCLUSIONS: Weight reduction is accompanied by favorable changes in the lipid parameters related to overweight and obesity, being more intense the greater the weight loss.

[Efficacy of motivational interventions in the treatment of overweight and obesity]. / Eficacia de las estrategias de motivacion en el tratamiento del sobrepeso y obesidad.

INTRODUCTION AND OBJECTIVES: Changing unhealthy behaviors: Diet and physical activity are key to treating obesity. The objective of this study is to determine whether an intervention group motivational intervention group by nurses trained by expert psychologist, complementary to the usual intervention is more effective than the latter in the treatment of overweight and obesity in relation to weight reduction percentage and the persistence over time of the reduction achieved. METHODS: A multicenter randomized clinical trial of intervention in overweight and obese patients. Randomization of the intervention by health areas (ZBS). Two groups located in different centers separated, one of which will receive motivational intervention group (study group) and the other routine monitoring (control group) were established. VARIABLES: Sociodemographic, results: percentage of patients reduced by 5% of its weight and maintenance over time, anthropometric assessment, assessment of cardiovascular risk factors and laboratory data. RESULTS: 696 patients were studied; 377 control and 319 study group. In both groups the weight down in each of the visits. The mean percentage weight reduction stood at 1% for the control group and 2.5% in the intervention group (p -value = 0.009). 55.8% of patients reduced the weight in the control group and 65.5% of the study group (p -value = 0.0391). 18.1% of the control patient lost more than 5% by weight, in the intervention group, this percentage increased to 26.9%; statistically significant ( p -value = 0.0304). For the 10% target no significant differences at 2 years were detected (5% vs. 8%). It was found that after two years the BMI in the control group an average 0.9 kg/m2 and 2.4 kg/m2 was reduced in the study group ( p -value = 0.0237). CONCLUSION: based motivational group intervention program can improve anthropometric and lifestyle parameters in obese patients treated in a primary care center.

Introducción y objetivos: La modificación de conductas no saludables: dietas y actividad física son fundamentales para tratar la obesidad. El objetivo de este estudio es determinar si una intervención de motivación en grupo, por profesionales de enfermería entrenados por psicólogo experto, complementariamente a la intervención habitual, es más eficaz que esta última en el tratamiento del sobrepeso y obesidad en relación a reducción porcentual del peso, y la persistencia en el tiempo de la reducción conseguida. Métodos: Ensayo clínico aleatorio multicéntrico de intervención en pacientes con sobrepeso y obesidad. Asignación aleatoria de la intervención por Zonas Básicas de Salud (ZBS). Se establecen dos grupos situados en centros diferentes separados, uno de los cuales recibirá la intervención de motivación en grupo (grupo de estudio) y el otro el seguimiento habitual (grupo control). Variables: Sociodemográficas, de resultados: porcentaje de pacientes que reducen un 5 % de su peso y mantenimiento en el tiempo, valoración antropométrica, valoración de factores de riesgo cardiovascular y datos analíticos. Resultados: Se evaluaron 696 pacientes; 377 grupo control y 319 del de estudio. En ambos grupos el peso descendía en cada una de las visitas. La reducción porcentual media del peso se situó en el 1% para el grupo control y del 2,5% en el grupo intervención (p-valor = 0,009). El 55,8% de los pacientes redujeron el peso en el grupo control y el 65,5% del grupo de estudio (p-valor = 0,0391). El 18,1% de los paciente del grupo control redujeron más del 5% del peso, en el grupo intervención este porcentaje aumentó hasta el 26.9%; estadísticamente significativo (p-valor = 0,0304). En el caso del objetivo del 10% no se detectaron diferencias significativas a los 2 años (5% vs. 8%). Se detectó que a los dos años el IMC en el grupo control se redujo una media 0,9 kg/m2 y 2,4 kg/ m2 en el grupo de estudio (p-valor = 0,0237). Conclusión: el programa basado en intervención motivacional en grupo puede mejorar parámetros antropométricos y estilos de vida en pacientes obesos tratados en un centro de Atención Primaria.

[Physical fitness level and its relationship with body weight status in school children]. / Nivel de condición física y su relación con el estatus de peso corporal en escolares.

OBJECTIVE: To explore and establish possible relationships between body weight status and fitness level in a sample of primary school children. METHODS: Descriptive and cross-sectional study. A total of 216 students (125 women 8-11 years) participated in the assessment of weight, height and physical condition. The body weight status (normal-weight, overweight and obesity) was categorized according to international standards. RESULTS: males have on average higher values in the running test 4x10 meters, manual dynamometry, longitudinal jump and Course-Navette. Women show a higher tendency to exceed healthy weight. The analysis showed that a high level of fitness is directly associated with normal weight status (p <.01). CONCLUSIONS: The results of this study suggest that students who have higher fitness levels are more likely to have a body weight status within normal parameters. Programs promoting physical activity, aimed to improve fitness, and thus the body status need to be implemented. Increasing physical education time at school or conducting educational programs focused on nutrition can be effective measures to improve overall health.

Objetivo: Analizar y establecer posibles relaciones entre el estatus de peso corporal y el nivel de condición física relacionado con la salud en una muestra de escolares de Primaria. Material y Método: Estudio descriptivo-transversal. Un total de 216 escolares (125 mujeres de 8-11 años) participaron en la evaluación del peso, talla y condición física (Batería ALPHA-Fitness). El estatus de peso corporal (normo-peso, sobrepeso y obesidad) fue categorizado usando estándares internacionales. Resultados: Los varones presentan en promedio valores superiores en el test de carrera 4x10 metros, dinamometría manual, salto longitudinal y Course-Navette. Las mujeres presentan una mayor tendencia a exceder el peso saludable. El análisis de varianza mostró que un nivel alto de condición física se asocia de manera directa con un estatus de normopeso (p< ,01). Conclusiones: Los resultados del presente estudio sugieren que los escolares que poseen niveles superiores de condición física presentan una mayor tendencia a un estatus de peso corporal dentro de parámetros normales. Se precisan programas de fomento de la actividad física con el fin de mejorar la condición física y con ello el estatus corporal de los jóvenes. Incrementar las horas de Educación física escolar o llevar cabo programas educativos centrados en la nutrición pueden ser medidas eficientes para mejorar el estado de salud general.
