The quality of drinking and running water had major influenced to human health. The use of comtanimated water could be cause of cholera, dysenteria, and typhoid outbreaks with different scales. Aside from many water-born diseases with the causes of microbilogy, chemical contamination also is a major threat for community health. So, it is necessary to strengthen control the quality of water by authorities and community

The study on the maternal risk factors affect to weight and height of their newborns among 813 newborns at Vinh Bao district, Hai phong city in 2001. Among these babies, 94 had low birth weight (<2500g), 719 with normal weight (>2500g). The results showed that mother’s height under 150 cm was highest risk factor related to weight and length of newborns, followed by mother’s weight under 45kg, mother’s head round under 54cm and placental weight under 500g. BMI of mother under 18.5 and weight increased less than 1 kg in first trimester only affected to the length of newborn babies

A study of intervention solutions for the exhaust from 4 thermo-electrical kilns, from synthetic process of in NH3 and dust due to NPK fertilizer production was carried out to evaluate the efficacy of technological improvement solutions in reducing environment pollution. Results: concentration of dust and toxic fumes was reduced, concentration of the exhaust components eliminated to environment through the chimneys of gases-made kilns reduced significantly after changing technology. NH3, CH4, H2 from producing NH3 decreased clearly, dust from producing NPK reduced 1.63-1.92 times

A retrospective study of 200 Kovacs has been applied in 2nd trimester abortion in 1997 and other 200 by MSP in 1998. -MSP could be efficacy in 2nd trimester abortion as Kovacs.-In first 48h, the natural abortion by MSP and Kovacs is the same.-The propotion of MSP abortion is higher than Kovacs, hospitalized stay length of MSP is shorter than Kovacs.-No infection in MSP trials

Cohort prospective study was carried out on 196 women with Papanicolaou (Pap) smears diagnosed as ASC, LSIL or AGC. Results: reference standard verification was available in 108 patients. The rate of DNA-aneuploidy in Pap smears increased significantly from cervical intraepithelial neoplasia (CIN) 1 (54%) and CIN2 (64.3%) to CIN3 or above (83.3%) in subsequent biopsies (p<0.05). Using ASC/LSIL/AGC as input cytological criteria and CIN2 or above as output histological diagnosis, positive predictive value (PPV) of conventional cytology and DNA-ICM was 35.2% and 65.9%, respectively (p<0.01). Negative predictive value (NPV) of DNA-ICM was 85.0%. Using CIN3 or above as output histological diagnosis, conventional cytology showed a PPV of 22.2%. PPV and NPV of DNA-ICM were 43.9% and 93.3%, respectively.

Polycystic ovarian syndrome (PCOS) was not considered as a simple disease at ovary but as a metabolic syndrome. The centre of this process is the disturbance of gonadotropin and metabolism of insulin/insulin-like growth factor 1 (IGF1). Some main symptoms: mentruation disorder, hyperandrogenaemia, obesity and hyperresistant to peripheral insulin with hyperinsulinaemia. For those patients have symptoms on skin, the local treatment is provided, other systemic treatments were used for those have metabolic diseases. Women with polycystic ovarian syndrome often are obesity. Metformin lose weight, regulate menstruation circle and increase significantly ovulation. Reducing androgen concentration can improve the symptom of acne and hypertrichosis. Infertile treatment, metformin can be effect in stimulating ovaries by clomiphen or FSH, increase the rate of having pregancy and reduce the rate of miscarriage in women with PCOS.

The study surveyed the morbidity and hospital admission of Bac Giang city population in the year 2001, especially the prevalence of cancer. 3.000 households were enrolled in the study. Data were collected and interviews were conducted. Analysis showed people had a high demand of health care in hospital, especially with cancer management. 31.1% of urban population demanded a hospital admission. In 5 year period in the city, the cancer incidence was 158.9/100.000 people in average. The highest was in 50-69 age group, and this incidence was higher in male than female

In Vinh Bao district, Hai Phong city in the year 2001, 825 female subjects aged 18-35 years old with first pregnancy or one child, without abortion or immature delivery, were divided into 2 groups according to BMI (For CED group: BMI < 18.5 and normal group: BMI  18.5). The prevalence of chronical energy deficit (CED) before pregnancy was 29%, among them, 1st grade CED 21.2%, 2nd grade 6.3%, 3rd grade 1.5%. The prevalence of common diseases (cough, fever, headache, diarrhoea…) in CED - 40.2%, higher than normal group - 26.3%. In general, for both two groups, morbidity reduced progressively in the course of pregnancy: the prevalence was 18.6% in the first trimestre, 8.8% in the second trimestre and 8.4% in the terminal 3rd trimestre. Considering body weight, in the first trimestre the weight gained by 0.48kg (CED group: 1.19lg, normal group 0.19kg), in 2nd trimestre, the weight gained 2.46kg (CED group 2.91kg, normal group 2.28kg), in the last 3rd trimestre 4.08kg (CED group 4.28kg, normal group 4.0kg).

The average incidence/case/year of Ha Bac nitrate and chemical factory during two years (2002-2003) was 1.38 incidence/case/year (2002) and 1.63 incidence/case/year (2003). The diseases were high incidence as follows: odonto-maxial-facial disease, ear-nose-throat disease. Workers with I health level and II health level were the highest: 70.33% (2002) and 65.05% (2003). The rate of workers with III health level were very high and tend to increase, remained the rate of workers with V health level.

Weight in average was 2911.4g (group of mothers with CED): 2905.6g; group of mothers without CED: 2913.8g, (boys: 2961g; girl: 2856g). Low birth weight rate was 11.6% (CED: 9.6%; normal: 12.4%); (boys: 10.4%; girls: 12.8%). Length of newborn babies in average was 48.3 cm (CED: 48.2 cm; normal: 48.4 cm), (boys: 48.6 cm; girls: 48 cm). Only 2.1% of newborn babies had length at birth lower 45 cm, nearly 98% had length at birth  45cm.
