Abstract

Background: Breast cancer can influence the quality of patient’s life. A measurement of quality of life (QOL) is important to evaluate the health services and the continuity of patient life. The Quality of Life Instrument (Quality of Life Breast Cancer Scale) by Ferrell, et al (1995) which has been translated into Indonesian as The Quality of Life Breast Cancer Instrument has not been tested its reliability.Objective: To know the instrument’s reliability and measuring agreement rating of breast cancer patient’s life quality between two raters.Method: This was an observational study using a cross-sectional study design. The subjects were 50 women with stage II-III of breast cancer at Sardjito Hospital selected using an accidental sampling technique. Data was collected through interviews using the QOL instrument guideline. Each subject was interviewed twice by nurse and midwife with 2-14 days difference between the interviews. The data were analyzed with Univariate, and Bivariate with Coefficient Kappa analysis, Intraclass Coefficient Correlation analysis, and alfa Cronbach Coefficient analysis.Results: The Kappa analysis to 46 items of quality of life questions done by nurse and midwife resulted in “good” and “very good” category. The lowest result was k=0.63 and the highest result was k=1.00. The lowest result of coefficient alpha analysis was r=0.63/0.63 while the highest was r=0.88/0.87. The lowest intraclass coefficient was r=0.93 while the highest was r=0.99.Conclusion: The quality of life breast cancer instrument could likely be adapted for breast cancer patients in Indonesia.Keywords: reliability, instrument, quality of life, breast cancer, Sardjito.

Abstract

Eating Behavior and the Prevalence of Premenstrual Syndrome in TeenagersBackground: Problems commonly encountered by teenagers in relation to menstruation are dysmenorrheal and premenstrual syndrome. Some recent studies reveal that micronutrients (calcium, magnesium and vitamin D) have an important role in causing disorder of mood and behavior during premenstruation. Teenagers generally consume foods with low nutrients and have a diet that causes lack of nutrient intake leading to menstrualdisorder.Objective: To identify the association between eating behavior and the prevalence of premenstrual syndrome in teenagers at District of Purworejo.Method: This was a case control study with quantitative approach. Subject of the study were students of SMKN 3 and SMAN I Purworejo. Analysis stage I was made to identify the prevalence of premenstrual syndrome (n=749). Analysis stage II was made to identify the association between eating behavior and the prevalence of premenstrual syndrome; the comparison between samples of cases and control was 1:1 (n=160).Result: The prevalence of premenstrual syndrome in teenagers was 24.6%. The test in eating behavior and premenstrual syndrome showed the result was statistically significant. When variable of stress was controlled, the risk for premenstrual syndrome was 2.3 times greater. The result of logistic regression analysis on nutrient intake showed that fat and potassium had the most dominant effect to the incidence of premenstrual syndrome with standardized coefficient value as much as 0.7982 and 0.7834 subsequently.Conclusion: Unhealthy eating behavior increased risk for premenstrual syndrome 2.3 times greater. Intake of fat and potassium most dominantly affected premenstrual syndrome.Keywords: eating behavior, premenstrual syndrome, teenagers

Abstract

Background: Reproductive health has not been fully incorporated into health education in the formal school system due to limited time allocation and teachers. Since media have become an inseparable part of adolescents’ life as more  than  just  their peer,  therefore, one  alternative  in  educating adolescents  on  reproductive  health  is  by using the E-file multimedia of ”The Information, Education and Communication Materials on Adolescent Reproductive Health”.Objective: To examine the effectiveness of adolescent reproductive health E-file multimedia as a method of health education in improving adolescents’ knowledge on reproductive health.Methods: The study was an experimental study designed using quasi experiment. Samples were selected by purposive sampling. Samples were 77 junior high school students. Data were analyzed using t test by applying multiple linear regressions in order to examine the difference in the average scores of adolescents’ knowledge on reproductive health.Results: The average score of health education on reproductive health using multimedia electronic file was 4.31 at deviation standard 1.32 whereas using face to face method in the classroom was 2.5 with deviation standard 1.39. Average difference in both methods was 1.8 at 95% CI (1.19 – 2.42) and p=0.00 or p<0.05.Conclusion: There was no difference between multimedia electronic file method and face to face method in improving knowledge of teenagers about reproductive health.Keywords: health education, knowledge E-file, multimedia, adolescent reproductive health.

Abstract

Background: The  report of  2002-2003  Indonesia’s  Demographic and Health Survey  (IDHS)  suggests  that  the prevalence  of  family  planning  in  Indonesia  reach  60   percent with  the  hormonal  contraceptive  increase  by  16 percent  and  the  non hormonal  contraceptive  decrease  by 7  percent. Generally,  the  choice  of contraceptives  is based  on  clear  reasons  to  regulate  the  birth  spacing or  to  limit  births. Factors  determining  the  choice  of  non hormonal contraceptives  include  physical  access  (distance),  economy  (cost),  administration  (service  resource) and  cognitive  accesses  (knowledge).Objective: To  investigate  the  relationship between  contraceptive  accesses and  the  choice of  hormonal and  non hormonal  contraceptives  in Purworejo District.Method:  This was  an observational  study with  a  case  control study  design.Subject: Samples were married women 20-35  years  of  age  that  became  the new  acceptors with  the choice  of non hormonal contraceptives  (IUD) as  the case  (133 women) and of hormonal contraceptives  (pill and  injectable) as  the  control  (133 women)  from  1 January  2004  to  31 December  2004.Data analysis: The  qualitative data  analyses used were univariable,  bivariable and multivariable. Statistical  test used  chi-square  and  logistic  regression.Results: The  bivariable  and multivariable  analyses  showed  that  there was  a  relationship  between  family planning demand  and  the  choice of  non hormonal  contraceptives. Respondent  residing  far  from  family  planning services  tended  to choose non hormonal contraceptives with a chance of 1.9  times higher  (OR=9.5;CI95%=1.16-3.19). The variable  that had  the greatest chance  to  influence  respondents  to choose non hormonal contraceptives was cost  that was  7.5  times  (OR=7.5; CI  95%  =  2.60-21.87). The  respondents  that  utilized  private  facilities tended  to  choose  non  hormonal  contraceptives.Conclusion: Respondents with  family  planning  demand  to  limit  births were  likely  to  choose  non  hormonal contraceptives. Other  factors  affecting  the  choice  of  non hormonal  contraceptives were  income.Keywords:  family  planning  accesses,  family  planning  demand,  choice  of   hormonal  and  non  hormonalcontraceptives,  case  control

Abstract

Background: Recent  controversial  reports  suggest  that  recipients  of  one dose  of DTP  vaccines had  higher mortality  than  children who  had  received  no DTP  vaccine. We   reanalyzed data  on vaccination  and  child  survival collected  from demographic  and health  surveillance  to  challenge previous  findings.Objectives: To estimate specific and non-specific effects of DTP vaccination on child mortality age 1-24 months under  routine vaccination  program  in  Indonesia.Methods: A  longitudinal  surveillance  data  provided  information  on 5647  children  below  24 months  of age who received DTP and  other vaccinations. The main  outcome measure was all-cause mortality. Background  factors associated with mortality were  collected,  such as:  sex,  birth  order, dead  sibling, mother’s  education and  family size. We assessed DTP vaccinations  as an  independent  factor with other  variables  in Cox’s  regression models with  time  dependent  covariates.Results: There  is  no  sex  differential  of mortality  among  children  in  Purworejo  even  after  considering  other factors using Cox  regression  analysis. Mortality was  lower  in  the  group  vaccinated with DTP vaccine  compared with  those  not  vaccinated,  the  relative  risk  of mortality  (RR)  being  0.56 with  95%  confidence  interval  (CI)  is 0.453–0.690. After controlling  for  the  background  factors,  recipient of DPT vaccines  continued  to  have  a  lower mortality with RR=0.74  (95% CI:  0.586–0.925). BCG  and measles  vaccines have  stronger  non-specific  effects compared  to  effects  of DTP  vaccines.Conclusion:    Through  specific  effect  against  targeted  diseases  and  a  non-specific  benefit  against  others illnesses,  the study  showed  reduced mortality among  children who  received DTP  vaccine. There  is no  reason to  change current  vaccination policy  because DTP was not  associated with  any  harmful  effect  among  girls.Keywords: non-specific  effects, DTP  Vaccine,  child  survival, Cox’s Regression

Abstract

Background: Recent  controversial  reports  suggest  that  recipients  of  one  dose  of DTP  vaccine  have  higher mortality  than  children who  have  received  no DTP  vaccine. Those  reports were mainly  derived  from African countries where mortality and malnutrion were  higher  than  Indonesia.Objectives: To  describe  specific  and  non-specific  effects  of DTP  vaccination  on  child mortality  age  1-24 months under  routine vaccination  program  in  Indonesia.Methods: During  period of  January 1  1995  to August 31,  2001  our  longitudinal  surveillance  data at  Purworejo district provided  information on 5647 children below 24 months of age who  received DTP and other vaccinations. The main  outcome measure was  all-cause mortality. Vaccination  status  on DTP, BCG,  and measles were collected  every  90 days  and  recorded  its  time  at  vaccination. Confounding  factors  associated with mortality were  also collected. This  first  report used  descriptive analysis  and a  survival curve  (Kaplan-Meier)  to  examine the  differential of mortality according  to sex  of  the  children and  among vaccinated  and  non-vaccinated  children with DTP, BCG,  and measles vaccines. The second  report will  use  survival  analysis  to  estimate specific  and non-sprecific  effects  of DTP  by  considering  time at  vaccination and  other counfounding  factors.Results: There  is no  sex differential  of mortality among  children  in Purworejo.  A  probability of  dying was  lower in  the  children vaccinated with DTP  vaccine compared with  those  not vaccinated DTP. Simmilarly,  vaccinated children with  BCG  and measles  have  lower mortality  compared  to  unvaccinated  children.  There  is  strong indication  that BCG and measles  have  stronger protected  effects  to  risk of  dying  than DTP.Conclusion:   The study showed  lower mortality among children who  received DTP, BCG, and measles vaccines compared  those unvaccinated.  There were  not enough  evidences  to  change current  vaccination policy  because DTP was not  associated with  any harmful  effect  among  girls.Keywords: non-specific  effects, DTP  vaccine–child  survival-  Kaplan Meier’s Curve

Abstract

Background: Infant mortality is a tragedy which cannot be easily forgotten by mothers and their family. Data on mortality from hospital or hospital-based cause of death was not representative. Community-based cause of death with verbal autopsy approach is a way to provide statistical data on mortality. Personnel of verbal autopsy are medical staff or skilled non-medical staff. Limited number of medical staff and midwifes has made all verbal autopsy processes impossible to be carried out by medical staff. Therefore a method of verbal autopsy needs to be developed by non medical staff. This method should be validated prior to its implementation.Objectives: The objective of the study was to identify verbal autopsy validity viewed from measurement process conducted by different measurement staff to reach final diagnose agreement on cause of infant mortality between medical and non medical staff compared to doctor’s diagnose as gold standard.Methods: The study used a diagnostic test with retrospective cohort research design. Numbers of samples were 110 cases and length of study was 3 months. Cases were taken from infant mortality which occurred in hospitals during the last 3 years with their medical records. Training was given for 1 / day to midwives and statistic officers on how to execute verbal autopsy. Questionnaires used were adapted from World Health Organization which had been translated and tested in on settings. Staff conducted measurement or interview with statistic officers and a week later with midwives.Results: Analysis result of Kappa statistical test showed that value of agreement between doctor’s diagnose and verbal autopsy by statistic officers was 0.57 with p=0.00. This meant that there was good agreement. Result of Kappa statistical test between midwifes and statistic officers was 0.63 with p=0.000. This also showed good agreement between midwife verbal autopsy and statistic officer verbal autopsy. Statistic officers could conduct verbal autopsy.Conclusion: Agreement reached between statistic officers and doctors diagnose was quite good. Statistic officers could conduct verbal autopsy.Keywords: verbal autopsy, validation, infant mortality

Abstract

Background: The 2002-2003 Indonesian Demographic and Health Survey (IDHS) data indicated an increase up to 41% in the number of children not breastfed until two years old. Previously, according to 1997 IDHS data, there were only 34% babies who were weaning before they had reached two years. This increase was in line with the increasing number of pregnant mothers utilizing health care and hormonal contraceptives.Objective: to explore the correlation between the length of breastfeeding and the behaviors of Indonesian pregnant mothers utilizing health care and hormonal contraceptives.Methodology: Using the cohort retrospective approach, the research was conducted upon 5940 mothers, who were 15 years to 49 years old. Each had at least one under-five-years-old child.  The proportional Odds Model was employed to analyze the ordinal out come of the study. The life table served to show the continuity of breastfeeding. The variables taken were the length of breastfeeding. ANC visits, contraceptive usage, ownership assets, educational level, working status, parity, residence, prelactal liquid and milk from bottles.Findings; The probability of breastfeeding up two years old between mothers with ANC visits and without ANC visits were notdifferent. The probability of breastfeeding until two years old between mothers using non-hormonal contraception was higher compared to hormonal ones. The risk of weaning before two years in mothers using hormonal contraception was higher (1.5 times) compared to those using non-hormonal contraception.Conclusion: Factors significantly correlated with breastfeeding period were women's behaviors and characteristic as well as the family's economic status, the declining median of breastfeeding period of Indonesian mothers had strong correlation with hormonal contraceptive usage and bottles milk.Keywords: breastfeeding, antenatal care, contraceptives, demography

Abstract

Background: Report of Indonesian Health and Demographic Survey (IHDS) 2002-2003 showed an increase of contraceptive use from 57% (1997) to 60% (2002-2003) among married women in Indonesia. The use of Injection method had the highest increase while Intra Uterine Device was decrease. Contraceptive method usually was used based on the reasons for controlling birth and birth spacing. The choice of contraceptive method was influenced by motivation, access and cost.Objective: The goal was to explore the determinant of IUD method use in Indonesia.Method: Data of IHDS 2002-2003 was analyzed using cross-sectional study design. Sample was married women aged 15-49 years old who use IUD method. Data was analyzed statistically using chi-square test and logistic regression at 95% significant level.Result: Logistic regression analysis showed a significant relationship between the demand of contraceptive use and IUD method use. Respondent with birth control reason had a probability of 2.8 times to use IUD (OR=2.8; CI 95%=2.45-3.13). Health service place and cost of service were also had a significant relationship with contraceptive use demand. Respondent who used government’s health facility had a probability to use IUD OR=1.9; CI 95%=1.67-2.06).Conclusion: Respondent with birth control reason tends to use IUD. Those who use government’s health facility and those who paid more than Rp200.000,00 were also tend to use IUD. Another factors influence IUD method use was age, parity, education level, economic status and residence status.Keywords: IUD, family planning, birth spacing
