Abstract
Awareness regarding incidence pattern of disease is an important issue for researchers. To
explore seasonal pattern of TB in Iran we decided to do this study.
This study have been done as an ecologic study .all notified TB cases during 1997 to 2001
have been included in this study .all data have been processed and analyzed by the Cosinor
analysis method.
We found 59756 registered TB cases during above mentioned years.
TB in this 5 year period has seasonal pattern (amplitude=11.73% ,acrophase=13 June(85.23) ,
p<0.000) .
Frequency of TB cases evaluated by sex in this model and found that there is seasonality by
sex too (p<0.000) , but different amplitudes found for female and male(13.35%, 10.5%) and
point estimate of acrophase for them were consequently 18 June and 8 June .
When we evaluate this pattern among smear positive and smear negative cases found that
smear positives have seasonal pattern (p<0.000) . Association of TB frequencies in quarters
and mean temperature of each quarter have been evaluated by ANOVA in different 4
temperature groups(p< 0.020) ,and a significant difference have been found between 10-20
and 20-30 temperature groups(p<0.051) .
According to this study there is a seasonal pattern in TB notification (incidence) in Iran which
should be notified in population based studies and surveys in this regards.
Comments:
We recommend performing more studies on patterns of pulmonary disease, other relevant
factors on TB involvement and also laboratory circulation to clarifying cause of existing
seasonality

Abstract
Background and Aim: Looking at population pyramid from the 1996 census and its estimates for the years 2003 and 2004, it is clear that the size of the elderly population will be greater in men than in women. According to Iran’s Ministry of Health, the life expectancy for women is greater than that for men. This article is devoted to the discussion and analysis of this paradox.
Materials and Methods: Analysis of the population sex ratio.
Results: Its trend- based on data generated by censuses from 1956 to 1996- indicate that a large proportion of women did not live beyond the age of 35 women were most likely to die in years 35-45 of their life. It is possible that this age group, which included many women who were still of reproductive age, suffered the effects of war and socioeconomic crises of the 1940's. The trend had improved by the time of the 1376 census and there is no singe of an increase in the sex ratio thereafter. This change is probably due to the improvement in socioeconomic status and the development of an effective health care system.
Conclusion: Since the life expectancy estimates are based on the probability of death and are thus affected by socioeconomic conditions, the apparent incompatibility between the population age pyramid and life expectancy among elderly women and men is due to higher mortality among women of reproductive age before the 1970’s.
