Normal standard for ventilatory function test in adult Filipinos

To establish reference values for lung function test in Filipinos, 283 (130 males and 153 females) normal non-smoking ( Multiple linear regressions with backward elimination was done. The data obtained was regressed against independent variables of age height, weight, and body surface area for each sex. Analysis of variance (ANOVA) of the regression equations for most parameters were significant at = 0.01. In a few parameters were significance was = 0.05. Only in Raw was the regression model not significant. The coefficient of determination (R) of our regression equations were low (

The accessibility and utilization of mobile phones among TB patients: A feasibility survey for short messaging service (SMS) as a strategy to improve adherence to TB services

OBJECTIVES: To estimate the proportion of TB patients who have access to mobile phones and to describe mobile phone utilization practices of TB patients. METHODS: Six public and six private TB clinics representing the four districts of Metro Manila and one institution in Cavite were purposively selected for this cross-sectional survey conducted in 2006. Using an interviewer-administered questionnaire, patients suspected to have TB, those newly diagnosed and those currently on treatment under either DOTS or non-DOTS were interviewed. RESULTS: Of the 337 patients interviewed, 65% (95% CI 60.2 to 70.6) have access to mobile phones (45% currently own a mobile phone and 20% share a mobile phone with a household member). The mean duration of ownership was 1.8 years (SD1.7). Almost all had prepaid subscriptions (99%) and 72% had some credit/load in their mobile phones at the time of interview. Of the three existing networks, subscription to SMART was highest, followed by the Globe network. Most of them use their phones for social purposes and emergency-related communications. Most of the respondents were male (60%) in the age group of 20-39 (54%) and 40-59 years old (33%). Half of the respondents were from public TB clinics (52%). On multivariable analysis, patients consulting in private clinics [OR 2.25, 95% CI 1.36 to 3.74], belonging to the younger age of CONCLUSION: Considering the fair access (65%) to mobile phones of the patients interviewed, it is feasible to conduct a pilot intervention using SMS as a strategy to improve adherence to treatment. The intervention should consider that majority use prepaid subscriptions and that sharing of phones among household members is a common practice.
