Statin Efficacy and Safety for Lipid Modification in Apparently Healthy Male Military Aircrew

Introduction: Military aircrew men represent an elite group of relatively young, fit, and healthy people. The effectiveness of statin treatment in reducing low-density lipoprotein cholesterol (LDL-C) according to the current National Cholesterol Education Program (NCEP) guidelines, its safety, and compliance in this group of people has not yet been determined. Methods: We prospectively evaluated 84 military aircrew men (mean age 43 Ϯ 7 yr) with LDL-C above the current NCEP guidelines. The patients were divided into two groups according to their coronary risk factors: Group 1, LDL-C goal Ͻ 160 mg ⅐ dL Ϫ1 ; Group 2, LDL-C goal Ͻ 130 mg ⅐ dL Ϫ1 . All patients received statins in addition to therapeutic lifestyle changes and were followed for a mean of 3 Ϯ 1 yr according to a simple flow chart. Lipoprotein levels, liver function tests, creatinine phosphokinase, and subjective adverse reactions were checked periodically. Results: LDL-C significantly declined by 32% (p Ͻ 0.0001) within the first month of treatment and 99% of subjects achieved their LDL-C goal within 114 Ϯ 35 d from statin therapy initiation. The Framingham estimated 10-yr coronary risk showed a reduction at an average of 12 mo after statin therapy initiation from a baseline value of 6.54% to 3.95% (p ϭ 0.003). No subjects were grounded or disqualified from duty, there were no cardiovascular events during follow-up, and compliance to therapy was high [82/84 (98%)]. Discussion: Statin treatment in this highly select, relatively young group of aircrew men significantly and safely lowered LDL-C cholesterol levels

Factors affecting study efficiency and item non-response in health surveys in developing countries: the Jamaica national healthy lifestyle survey

BACKGROUND: Health surveys provide important information on the burden and secular trends of risk factors and disease. Several factors including survey and item non-response can affect data quality. There are few reports on efficiency, validity and the impact of item non-response, from developing countries. This report examines factors associated with item non-response and study efficiency in a national health survey in a developing Caribbean island. METHODS: A national sample of participants aged 15–74 years was selected in a multi-stage sampling design accounting for 4 health regions and 14 parishes using enumeration districts as primary sampling units. Means and proportions of the variables of interest were compared between various categories. Non-response was defined as failure to provide an analyzable response. Linear and logistic regression models accounting for sample design and post-stratification weighting were used to identify independent correlates of recruitment efficiency and item non-response. RESULTS: We recruited 2012 15–74 year-olds (66.2% females) at a response rate of 87.6% with significant variation between regions (80.9% to 97.6%; p < 0.0001). Females outnumbered males in all parishes. The majority of subjects were recruited in a single visit, 39.1% required multiple visits varying significantly by region (27.0% to 49.8% [p < 0.0001]). Average interview time was 44.3 minutes with no variation between health regions, urban-rural residence, educational level, gender and SES; but increased significantly with older age category from 42.9 minutes in the youngest to 46.0 minutes in the oldest age category. Between 15.8% and 26.8% of persons did not provide responses for the number of sexual partners in the last year. Women and urban residents provided less data than their counterparts. Highest item non-response related to income at 30% with no gender difference but independently related to educational level, employment status, age group and health region. Characteristics of non-responders vary with types of questions. CONCLUSION: Informative health surveys are possible in developing countries. While survey response rates may be satisfactory, item non-response was high in respect of income and sexual practice. In contrast to developed countries, non-response to questions on income is higher and has different correlates. These findings can inform future surveys

Changing Parent’s Mindfulness, Child Management Skills and Relationship Quality With Their Youth: Results From a Randomized Pilot Intervention Trial

We evaluated the efficacy of a mindful parenting program for changing parents’ mindfulness, child management practices, and relationships with their early adolescent youth and tested whether changes in parents’ mindfulness mediated changes in other domains. We conducted a pilot randomized trial with 65 families and tested an adapted version of the Strengthening Families Program: For Parent and Youth 10–14 that infused mindfulness principles and practices against the original program and a delayed intervention control group. Results of pre-post analyses of mother and youth-report data showed that the mindful parenting program generally demonstrated comparable effects to the original program on measures of child management practices and stronger effects on measures of mindful parenting and parent–youth relationship qualities. Moreover, mediation analyses indicated that the mindful parenting program operated indirectly on the quality of parent–youth relationships through changes in mindful parenting. Overall, the findings suggest that infusing mindful parenting activities into existing empirically validated parenting programs can enhance their effects on family risk and protection during the transition to adolescence
